1. Jog Forward
2. Jog Reverse
3. Normal Operation
To activate jog operation, use a programmable input (Par. 3-3). If any other command is received when jogging, the starter will stop and await a new
command.
NB!
Jog is only available for the primary motor. Soft start and soft stop are not available during jog operation.
Slow speed running is not intended for continuous operation due to reduced motor cooling. Jog changes the motor's heating profile
and reduced the accuracy of the motor thermal model. Do not rely on motor overload protection to protection to protect the motor
during jog operation.
5.6 Inside Delta Operation
AAC, Jog and Brake functions are not supported in inside delta (six-wire) operation. If these functions are programmed when the starter is connected
inside delta the behaviour is as given below:
AAC Start
The starter performs a Constant Current Start.
AAC Stop
The starter performs a TVR Soft Stop if Stop Time is >0 secs. If Stop Time is set to 9 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.
NB!
When connected in inside delta, current imbalance is the only phase loss protection that is active during run. Do not disable current
imbalance protection during inside delta operation.
Inside delta operation is only possible with mains voltage
≤
600 VAC.
