SE1 fault (SE1:Contactor Feed-back Faults)
There are 3 possible fault conditions.
Case 1: The motor contactor was closed (Contactor feedback input was on) before the contactor close
command was output.
Case 2: The motor contactor cannot be closed within the contactor close delay time.
Case 3: The motor contactor is opened during inverter run.
Case 4: The contactor confirmation input was enabled before the contactor close output was set.
 Changing the PG direction
A digital input can be used to change over the PG feedback signal direction. Therefore one of the parameters
H1- must be set to 89.
The PG direction is clockwise (CW) when the input is open and counterclockwise (CCW) when the input is
closed. The parameter F1-05 has no effect if this function is activated.
