Issues of driving the wound rotor motor inverter

The wound rotor motor can be used in the same way as cage-induction motors by shortening the resistor at the secondary side. More Details >>

Operation of the motor with a brake

For the general-purpose inverter, the motor stop cannot be detected accurately because the actual motor speed from a motor is not input. In general, the RUN ... More Details >>

Countermeasure against the fault occurrence

When a CC-Link communication fault occurs, the option error (OP3) occurs on the inverter and the output is shut off, and the motor starts coasting. When usin... More Details >>

No load current value of motor

No load current for each power supply voltage is as follows:- Approximately 15.5 A for 200 VAC 60 Hz- Approximately 21.7 A for 220 VAC 60 HzThe current is es... More Details >>

Torque characteristic at low speed

Torque is not guaranteed for slower than 0.5 Hz. Therefore, no data for this is published. Also, no torque is generated at 0 Hz. More Details >>

"Err" displayed at power-ON

This error is displayed when the inverter and operation panel FR-PU04 cannot communicate with each other correctly or the reset signal remains ON. Therefore,... More Details >>

Common terminals of control circuit

If you ground the common terminals of the control circuit, it is connected with the inverter's earthing and the inverter's noise may be input to the control ... More Details >>

Control circuit power supply

If the MC on the input side is shut off using the fault output of the FR-E500, the inverter's fault records are left in the faults history. More Details >>

Trace function

The ST1 is a setting file and the TR1 is a waveform file. More Details >>
