Inside Delta Operation
Adaptive Control, Jog, Brake and PowerThrough functions are not supported with inside delta (six-wire) operation. If these functions
are programmed when the starter is connected inside delta the behaviour is as given below:
Adaptive Control Start
The starter performs a constant current start.
Adaptive Control Stop
The starter performs a TVR soft stop if parameter 2I Stop Time is >0 secs. If parameter 2I is set to
0 secs the starter performs a coast to stop.
Jog
The starter issues a warning with the error message Unsupported Option.
Brake
The starter performs a coast to stop.
PowerThrough
The starter trips with the error message Lx-Tx Shorted.
NOTE
When connected in inside delta, current imbalance is the only phase loss protection that is active during run. Do not
disable current imbalance protection (parameter 4A) during inside delta operation.
CAUTION
Inside delta operation is only possible with mains voltage
d
600 VAC.
