What does 'EEPROM fail' mean on my Nidec Digistart D4?
An 'EEPROM fail' error on the Nidec Controller indicates that an error occurred while loading data from the EEPROM to RAM when the keypad powered up. If the problem persists, contact your local distributor.
Why is there a current imbalance in my Nidec Digistart D4 Controller?
Current imbalance in the Nidec Controller can stem from several issues related to the motor, environment, or installation: * An imbalance in the incoming mains voltage. * A problem with the motor windings. * A light load on the motor. * A phase loss on input terminals L1, L2 or L3 during Run mode. * A failed SCR (diagnose by replacing the SCR and checking the starter's performance). Related parameters: 5A, 5B, 6C.
What does 'Depth Sensor' mean on my Nidec Controller?
The smart card has detected a fault with the depth sensor.
