・In order to start the shockless PID, normal operation is
performed with the base frequency × [AH-76] as the
target frequency from the start of operation to the set
time of [AH-80].
・The acceleration time at soft start can be set with
[AH-78].
・When an error is judged, the operation changes
depending on the setting of [AH-81] PID soft start
error detection enable.
- If [AH-81] is 00, nothing is done.
- If [AH-81] is 01, the abnormal state will trip with
[E120] PID start error after the set time of [AH-80]
has elapsed.
- If [AH-81] is 02, the output terminal 093[SSE] PID
soft start error signal turns ON after the abnormal
state has passed for the [AH-80] setting time.
- Output terminal 093[SSE] signal is turned ON while
the inverter is in running.
