After changing frequency on Shihlin AC drive, the value will be saved on EEPROM, since EEPROM has access limitation (around 100,000 times), in order to extend its life, the value will be saved in RAM first, then write to EEPROM after 30 seconds. If having needs to shut down the AC drive right after frequency setup, using H1009 instead of H1002 is suggested. Find quick answers in the Shihlin Electric FAQ—selection, wiring and troubleshooting for circuit breakers, magnetic contactors, AC drives, servo, HMI and PLC control.
