Do not remove the cover except for periodic inspections or wiring, even if the input power is not applied. Otherwise, you may access the charged circuits and get an electric shock.
Wiring and periodic inspections should be performed at least 10 minutes Improper operation may result in slight to medium personal injury or property damage. Improper operation may result in serious personal injury or death.
Otherwise, you may get an electric shock. Operate the switches with dry hands. Do not use the cable when its insulating tube is damaged. Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Do not place flammable material nearby. Otherwise, fire could occur.
Disconnect the input power if the inverter gets damaged. Otherwise, it could result in a secondary accident and fire. After the input power is applied or removed, the inverter will remain hot for a couple of minutes. Otherwise, you may get bodily injuries such as skin-burn or damage. Do not apply power to a damaged inverter or to an inverter with parts missing even if the installation is complete. Do not allow lint, paper, wood chips, dust, metallic chips or other foreign matter into the drive.
Otherwise, fire or accident could occur. E Do not stack the inverter boxes higher than the number recommended. E Install according to instructions specified in this manual. E Do not open the cover during delivery. E Do not place heavy items on the inverter. E Check the inverter mounting orientation is correct.
E Do not drop the inverter, or subject it to impact. E Follow your national electrical code for grounding. Recommended Ground impedance for V Class is below ohm and for V class is below 10 ohm. See the nameplate for the rated inverter current.
Bit 0 LV 1 0 0 1 Fault output relay operates at Low voltage trip. Bit 1 Trip 1 0 10 Fault output relay operates at any fault except Low voltage and BX inverter disable fault. Bit 2 Retry 1 10 0 Fault output relay operates when the retry number set in FU decreases to 0 by faults. When several faults occurred at the same time, Bit 0 has the first priority. This number is used in communication between inverter and communication board. This is used in communication between inverter and communication board.
Reference There are two kinds of loss of frequency reference. One is the loss of digital frequency reference and the other is of analog frequency reference. FreeRun Coast to stop 1 Inverter cuts off its output. This is the time inverter determines whether there is a frequency reference or not.
Users can use any kind of RS converters. However a converter that has built-in automatic RTS control is highly recommended. Because the specifications of converters depend on the manufacturers, please refer to the manual for detailed converter specifications.
If not, it can cause personal injury or damage other equipment. To ensure stable communication, limit the length below m.
Terminal INV. Terminal JP1 switch on the right upper side of control terminal block should be shorted using jumper to connect a terminating resistor at the end inverter connected.
But, do not connect the load until stable communication between the computer and the inverter is verified. Troubleshooting if the communication is not operating normally. Drive No. The Drive No. ENQ Drive No.
In this case, Request for Write Twice. From the second time of transmission, the exactly same data will be transmitted.

Over Voltage protection The inverter turns off its output if the DC voltage of the main circuit increases higher than the rated value when the motor decelerates or when regenerative energy flows back to the inverter due to a regenerative load.
This fault can also occur due to a surge voltage generated at the power supply system. Heat Sink Over Heat The inverter turns off its output if the heat sink over heats due to a damaged cooling fan or an alien substance in the cooling fan by detecting the temperature of the heat sink. Electronic Thermal The internal electronic thermal of the inverter determines the over heating of the motor. If the motor is overloaded the inverter turns off the output.
The inverter cannot protect the motor when driving a multi-pole motor or when driving multiple motors, so consider thermal relays or other thermal protective devices for each motor. Insufficient torque or over heating of the motor can occurs when the input voltage of the inverter drops. The inverter checks whether the phase is open by detecting the DC voltage of the main circuit. The inverter detects the output current to check the phase open of the output.
Take caution when using this function. External Fault A Use this function if the user needs to turn off the output by an external fault signal. Normal Open Contact External Fault B Use this function if the user needs to turn off the output by an external fault signal.
Fan fault The cooling fan does not rotate. Ground Fault A ground fault occurs. Inverter checks ground fault only when power is ON and run command is entered. The smallest number will be the most current fault in its memory. Check the operating information prior to fault. The auto retry number will be initialized when the user resets the inverter.
Heat Sink Overheat 1 Cooling fan is damaged or an alien substance is inserted. Electronic Thermal 1 Motor has overheated. Low Voltage Protection 1 Line voltage too low. Welding machine, motor with high starting current connected to the commercial line 3 Damaged or faulty magnetic switch at input side of inverter. Output Phase Open 1 Faulty contact on the magnetic switch at the output.
Inverter Overload 1 Load is larger than inverter rating. LED charge lamp on? Motor connected correctly? Forward and reverse signals inputted simultaneously to inverter? Inverter receiving command input frequency signal?
Operation mode FU set correctly? Command frequency set to 0? The motor rotates in opposite directions Phase sequence of output terminal U, V and W correct? The difference between the rotating speed and the reference is too big Reference frequency verified? Check the level of input signal Following parameter setting verified? Load too large? Torque Boost FU, 28 value too high? Current limit function and the stall prevention function verified? The motor current is too high Load too large?
Torque Boost Value manual too high? Is Stall prevention function FU, 60 verified? The rotating speed oscillates when the inverter is operating. The tester can display terminal is shorted for a short time and then display several mega-ohms because of the electrolytic capacitor.
If all measured values are about the same, individual modules are OK. To avoid this, it is recommended to perform routine inspections. Be sure to perform maintenance only after checking that the DC bus has discharged.
The bus capacitors in the electronic circuit can still be charged even after the power is turned off. The correct output voltage can only be measured by using a rectifier voltage meter.
Other voltage meters including digital voltage meters are likely to display incorrect values caused by the high frequency PWM output voltage of the drive. The conditions of the installation location. The conditions of the drive cooling. Abnormal vibration. Abnormal heating. If so, tighten up or replace. Any deposits inside of the drive of cooling fan?
If so, remove the deposits using air. Any abnormal contacts in the various connectors of the drives PCB? If so, check the condition of the connector in question.
