Frequency setting

Ensure that the inverter is in the PU operation mode and stopped, change the following parameters: 1. Read Pr.923 (Built-in frequency setting potentiometer g... More Details >>

Priority of multi-speed setting and frequency setting signals

For frequency setting, multi-speed setting is prioritized over current input. Therefore, when the multi-speed signal is input, the inverter switch to multi-s... More Details >>

Inverter control power supply

The FR-E540 uses common input for the control power supply and main circuit power supply. (It has only one power supply input terminal.) Therefore, you canno... More Details >>

Output specification between FM and SD

The output signal across FM and SD is pulse output. The output frequency and number of pulses of the output signal across FM and SD are proportional. However... More Details >>

Remote operation of the inverter

The wiring length of the start signal (STF etc.) is 30 m or less. The circuit voltage of the control input signals (terminal STF etc.) is 24 VDC and the volt... 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 >>

Monitor

The output current monitor of the inverter displays the output current effective value of the three phases measured by the current sensor. It does not displa... More Details >>

Operation panel and FR-PA07

Since the operation panel and PU connector cannot be specified for command source at the same time, they cannot be used together. More Details >>

RS-485 communication

It is available since June, 2007. The model is FR-E7TR. More Details >>

Stop-on-contact control

When the brake sequence function is enabled, the RT signal is disabled and the stop-on-contact control cannot be performed. More Details >>
