UTOMATIC
RESTART
,
TRIAL
TIME
The Automatic restart function restarts the inverter when the faults have dis-
appeared and the waiting time has elapsed.
The time count starts from the first autorestart. If the number of faults occurring
during the trial time exceeds three, the fault state becomes active. Otherwise
the fault is cleared after the trial time has elapsed and the next fault starts the
trial time count again. See Figure 9.13.
If a single fault remains during the trial time, a fault state is true.

9.10 PI CONTROL PARAMETERS (CONTROL PANEL: MENU PAR -> P12)
12.2 PI
CONTROLLER
GAIN
This parameter defines the gain of the PI controller. If the value of the param-
eter is set to 100% a change of 10% in the error value causes the controller
output to change by 10%.
12.3
PI
CONTROLLER
I-
TIME
This parameter defines the integration time of the PI controller. If this param-
eter is set to 1,00 second the controller output is changed by a value corre-
sponding to the output caused from the gain every second. (Gain*Error)/s.
