Inverter and peripheral devices Three-phase AC power supply Use within the permissible power supply specifications of the inverter. Moulded case circuit breaker MCCB or earth leakage circuit breaker ELB , fuse The breaker must be selected carefully since an in-rush current flows in the inverter at power on.
Magnetic contactor MC Install the magnetic contactor to ensure safety. Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter life to be shorten. The inverter may be damaged if you do not use reactors.
Select the reactor according to the model. Install a noise filter to reduce the electromagnetic noise generated from the inverter.
Effective in the range from about 1MHz to 10MHz. When more wires are passed through, a more effective result can be obtained. A wire should be wound four turns or more. Braking capability can be improved. A wire should be wound four turns at a maximum. Install this as required. Earth Ground Devices connected to the output Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the output side of the inverter.
When installing a moulded case circuit breaker on the output side of the inverter, contact each manufacturer for selection of the moulded case circuit breaker.
Earth Ground To prevent an electric shock, always earth ground the motor and inverter. For reduction of induction noise from the power line of the inverter, it is recommended to wire the earth ground cable by returning it to the earth ground terminal of the inverter.
NOTE The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure. Refer to page 8 Wrong wiring might lead to damage of the inverter.
The control signal lines must be kept fully away from the main circuit to protect them from noise. Refer to page 14 Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side. This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are connected, immediately remove them. Refer to page Refer to the instruction manual of each option and peripheral devices for details of peripheral devices.
Check the inverter type of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity. Refer to the following list and prepare appropriate peripheral devices: Motor Inverter Type. Select an MCCB according to the power supply capacity. Install one MCCB per inverter. Magnetic contactor is selected based on the AC-1 class. The electrical durability of magnetic contactor is , times.
When the magnetic contactor is used for emergency stop during motor driving, the electrical durability is 25 times. When using the MC for emergency stop during motor driving or using on the motor side during commercial-power supply operation, select the MC with class AC-3 rated current for the motor rated current. NOTE When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the inverter type and cable and reactor according to the motor output.
When the breaker on the inverter primary side trips, check for the wiring fault short circuit , damage to internal parts of the inverter, etc. The screws cannot be removed.
Installation hook. Reinstallation Example of FR-D 1 Insert the two fixed hooks on the lower side of the front cover into the sockets of the inverter. NOTE Fully make sure that the front cover has been reinstalled securely. The same serial number is printed on the capacity plate of the front cover and the rating plate of the inverter.
Since these plates have the same serial numbers, always reinstall the removed cover onto the original inverter. Hold the side of the wiring cover, and pull it downward for removal. To reinstall, fit the cover to the inverter along the guides. Also pull the wiring cover downward with holding a frontal part of the wiring cover. See below diagram for wiring cover of FR-D Hold the dent of the wiring cover marked with an arrow with thumb and the side with other fingers and pull downward for removal.
The cover can be removed easily by pulling it toward you. When an inverter panel is to be designed and manufactured, heat generated by contained equipment, etc. The inverter unit uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the inverter in the ambient environment that completely satisfies the equipment specifications.
As the inverter installation environment should satisfy the standard specifications indicated in the following table, operation in any place that does not meet these conditions not only deteriorates the performance and life of the inverter, but also causes a failure.
Refer to the following points and take adequate measures. Environmental standard specifications of inverter Item Surrounding air temperature Ambient humidity Atmosphere Maximum altitude Vibration. Always operate the inverter within this temperature range. Operation outside this range will considerably shorten the service lives of the semiconductors, parts, capacitors and others. Take the following measures so that the surrounding air temperature of the inverter falls within the specified range.
Refer to page 10 Install the panel in an air-conditioned electrical chamber. Block direct sunlight. Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source. Ventilate the area around the panel well. Do not power off the inverter. Keep the start signal of the inverter off. Avoid installing the inverter near the air outlet of an air conditioner. Too high humidity will pose problems of reduced insulation and metal corrosion.
On the other hand, too low humidity may produce a spatial electrical breakdown. Take dry air into the enclosure from outside. Provide a space heater in the enclosure. Condensation causes such faults as reduced insulation and corrosion. Take the measures against high humidity in 1. Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due to moisture absorption of accumulated dust and dirt, and in-enclosure temperature rise due to clogged filter.
In the atmosphere where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in a short time. Since oil mist will cause similar conditions, it is necessary to take adequate measures. Countermeasures Place in a totally enclosed enclosure. Take measures if the in-enclosure temperature rises.
Refer to page 10 Purge air. Pump clean air from outside to make the in-enclosure pressure higher than the outside-air pressure. If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the relays and switches will result in poor contact.
In such places, take the measures given in Section 3. As the inverter is non-explosion proof, it must be contained in an explosion proof enclosure. In places where explosion may be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and has passed the specified tests.
This makes the enclosure itself expensive including the test charges. The best way is to avoid installation in such places and install the inverter in a non-hazardous place. Use the inverter at the altitude of within m If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric strength.
Maximum m The vibration resistance of the inverter is up to 5. Vibration or impact, if less than the specified value, applied for a long time may make the mechanism loose or cause poor contact to the connectors.
Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break. Countermeasures Provide the panel with rubber vibration isolators. Strengthen the structure to prevent the enclosure from resonance. Install the enclosure away from sources of vibration.
From the enclosure that contains the inverter, the heat of the inverter and other equipment transformers, lamps, resistors, etc. The cooling systems are classified as follows in terms of the cooling calculation method. Cooling System. Installation of the inverter Enclosure surface mounting Remove the front cover and wiring cover to fix the inverter to the surface.
FR-D to NOTE When encasing multiple inverters, install them in parallel as a cooling measure. Install the inverter vertically. To ensure ease of heat dissipation and maintenance, leave at least the shown clearances around the inverter.
At least the following clearances are required under the inverter as a wiring space, and above the inverter as a heat dissipation space. Surrounding air temperature and humidity. When surrounding air temperature exceeds 40 C F , clearances between the inverters should be 1cm 0. Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be heat resistant.
When multiple inverters are placed in the same enclosure, generally arrange them horizontally as shown in the right figure a. When it is inevitable to arrange them vertically to minimize space, take such measures as to provide guides since heat from the bottom inverters can increase the temperatures in the top inverters, causing inverter failures.
When mounting multiple inverters, fully take caution not to make the surrounding air temperature of the inverter higher than the permissible value by providing ventilation and increasing the enclosure size. Heat generated in the inverter is blown up from the bottom of the unit as warm air by the cooling fan. When installing a ventilation fan for that heat, determine the place of ventilation fan installation after fully considering an air flow.
Air passes through areas of low resistance. Make an airway and airflow plates to expose the inverter to cool air. Always read the instructions before using the equipment. Control input signals No voltage input allowed Forward Terminal functions vary rotation start with the input terminal Reverse assignment Pr.
Terminal 10 and terminal 2 are used as PTC input terminal Pr. Connected to terminal SD inside of the inverter. NOTE To prevent a malfunction caused by noise, separate the signal cables more than 10cm 3. Also separate the main circuit wire of the input side and the output side. After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in an enclosure etc. The output of the single-phase power input specification is three-phase V. Phase need not be matched. Never connect the power cable to the U, V, W of the inverter.
Doing so will damage the inverter. Connect the motor to U, V, W. Turning on the forward rotation switch signal at this time rotates the motor counterclockwise when viewed from the load shaft. If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency.
The following table indicates a selection example for the wiring length of 20m The cable size is that of the cable HIV cable V class 2 vinyl-insulated cable etc. Assumes that the surrounding air temperature is 50C F or less and the wiring distance is 20m The recommended cable size is that of the cable THHW cable with continuous maximum permissible temperature of 75C F.
Assumes that the surrounding air temperature is 40C F or less and the wiring distance is 20m Selection example for use mainly in the United States. The recommended cable size is that of the cable THHW cable with continuous maximum permissible temperature of 70C F. Selection example for use mainly in Europe.
NOTE Tighten the terminal screw to the specified torque. A screw that has been tightened too loosely can cause a short circuit or malfunction. A screw that has been tightened too tightly can cause a short circuit or malfunction due to the unit breakage.
Use crimping terminals with insulation sleeve to wire the power supply and motor. Earthing Grounding precautions Always earth ground the motor and inverter. An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to manufacture an insulating material that can shut off a leakage current completely, and actually, a slight current flow into the case.
The purpose of earthing grounding the case of an electrical apparatus is to prevent operator from getting an electric shock from this leakage current when touching it. To avoid the influence of external noises, this earthing grounding is important to audio equipment, sensors, computers and other apparatuses that handle low-level signals or operate very fast.
Therefore, these two types should be discriminated clearly, and the following work must be done to prevent the leakage current having the inverter's high frequency components from entering the malfunction prevention type earthing grounding : a Where possible, use independent earthing grounding for the inverter. If independent earthing grounding I is impossible, use joint earthing grounding II where the inverter is connected with the other equipment at an earthing grounding point.
Joint earthing grounding as in III must be avoided as the inverter is connected with the other equipment by a common earth ground cable. Also a leakage current including many high frequency components flows in the earth ground cables of the inverter and inverter-driven motor.
Therefore, they must use the independent earthing grounding method and be separated from the earthing grounding of equipment sensitive to the aforementioned noises.
In a tall building, it will be a good policy to use the noise malfunction prevention type earthing grounding with steel frames and carry out electric shock prevention type earthing grounding in the independent earthing grounding method. Earthing Grounding must conform to the requirements of national and local safety regulations and electrical codes. Use an neutral-point earthed grounded power supply for V class inverter in compliance with EN standard. The earth ground cable should be of not less than the size indicated in the table on the previous page The overall wiring length for connection of a single motor or multiple motors should be within the value in the table below.
When driving a V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.
Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast response current limit function, or stall prevention function or a malfunction or fault of the equipment connected on the inverter output side.
If malfunction of fast-response current limit function occurs, disable this function. If malfunction of stall prevention function occurs, increase the stall level. Refer to page 79 for Pr. When using the automatic restart after instantaneous power failure function with wiring length exceeding below, select without frequency search Pr. Control circuit terminal indicates that terminal functions can be selected using Pr. Description Turn on the STF signal to start forward rotation and turn it off to stop.

Output frequency initial Analog signal output The output signal is setting proportional to the magnitude of the corresponding monitoring item. Inverter output shutoff When using the safety stop function, remove this shorting wire, and connect to a safety relay module. Line 2. Changing the control logic The input signals are set to sink logic SINK when shipped from the factory.
To change the control logic, the jumper connector above the control terminal must be moved to the other position. Change the jumper connector position before switching power on. The capacity plate is placed on the front cover and the rating plate is on the inverter. The sink-source logic change-over jumper connector must be fitted in only one of those positions.
If it is fitted in both positions at the same time, the inverter may be damaged. Control circuit specifications 1 Sink logic type and source logic type In sink logic, a signal switches on when a current flows from the corresponding signal input terminal. Terminal SD is common to the contact input signals. Terminal SE is common to the open collector output signals.

Binary code 12 max FFFH. Convert connectors to e-CON. Power supply voltage: 24VDC. Power consumption: 25W. Weight kg Size WxHxD mmx90x Decreasing current may increase the life.
However, decreasing current will result in insufficient torque and the inverter may not start. Therefore, choose the inverter which has enough allowance for current up to 2 rank larger in capacity. Use shield cables as signal cables. When the wiring is incorrect and if there is a bypass operation circuit as shown right, the inverter will be damaged due to arcs generated at the time of switch-over or chattering caused by a sequence error.
However, a fault output signal may not be output at an inverter fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures best quality products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to machine when the inverter fails for some reason and at the same time consider the system configuration where failsafe from outside the inverter, without using the inverter, is enabled even if the inverter fails.
For example, when the inverter CPU fails, even if the interlock is provided using the inverter fault signal, start signal and RUN signal, there is a case where a fault signal is not output and RUN signal is kept output even if an inverter fault occurs. Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the backup system such as checking up as below according to the level of importance of the system.
Note that the motor current runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if the start signal turns OFF. For the logic check, configure a sequence considering the inverter deceleration time. In addition, it is recommended to check the three-phase current when using the current detector.
Inverter Controller System failure To the alarm detection sensor Sensor speed, temperature, air volume, etc.
