Cause:

E-18: Analog input disconnecting fault occurs when the input on the II terminal falls lower
than the values set in Parameter F633 [II analog input disconnection detection level]

Clearing:

broken at any point during the run.
Verify that you are seeing a DC input current that is larger than the value in F633.

consider adjusting F633 above this minimum level.

Inspect the motor and driven equipment for issues prior to clearing any faults.

• The [STOP/RESET] button on the AS3 keypad was pressed twice in quick succession
• Activate a digital input that has been programmed to “Reset” function
• Set the tyP (F007) Parameter to: 4: Clear past trips

Discussion
