REMARKS
• If the reset signal (RES) is provided during operation, the inverter shuts off its output while it is reset, the internal thermal
integrated value of the electronic thermal relay function and the number of retries are reset, and the motor coasts.
• The Pr. 75 value can be set any time. This value does not return to the initial value if parameter (all) clear is executed.

Alternatively, you can make a restart by making a power-on reset or resetting the inverter using the reset terminal of
the inverter.
REMARKS
• If the reset signal (RES) is provided during operation, the inverter shuts off its output while it is reset, the data of the
electronic thermal relay function and the number of retries are reset, and the motor coasts.
• To make a restart, confirm that the PU is connected and then reset the inverter.
• The Pr. 75 value can be set any time. This value does not return to the initial value if parameter (all) clear is executed.
• When the motor is stopped from the PU, PS is displayed. An alarm output is not provided.
• Since PS is not an inverter error, the inverter can not be reset with
Do not reset the inverter with the start signal input.
Doing so will start the inverter immediately after it has recovered from the error, causing hazard.
