Resetting the inverter (Reset)

After you have located and corrected the cause of a shutdown you need to reset the inverter so that
normal operation can continue. In addition to clearing the error history, executing a RESET also clears
the stored record of the number of restart attempts and the stored values registered for the electronic
thermal overload relay.
Three different ways to reset the inverter are available:
● Reset by pressing the STOP/RESET key on the parameter unit.
After a fault occurred (a protective function is activated to trip the inverter) you can reset the
inverter by pressing the STOP/RESET key.
● Reset by switching the power supply to the inverter off and on again.
● Reset with an external RESET signal
You can reset by briefly (but at least 0.1s) connecting terminals RES and SD (sink logic) or RES and
PC (source logic). Never make a permanent connection between the RES terminal and the SD or
PC terminal!
