7.7. Jog Operation
Jog runs the motor at reduced speed, to allow alignment of the load or to assist servicing. The motor can be
jogged in either forward or reverse direction.
The maximum available torque for jog forward is approximately 50%~75% of motor full load torque (FLT)
depending on the motor. The torque when the motor is jogged in reverse is approximately 25% to 50% of FLT.
Parameter 15F Jog Torque controls how much of the maximum available jog torque the soft starter will apply to
the motor.
NOTE
Setting parameter 15F above 50% may cause increased shaft vibration.

To activate jog operation, use a programmable input (parameter 6D). If any other command is received when
jogging the starter will stop and await a new command.
NOTE
Soft start and soft stop are not available during jog operation.
Jog is only available for the primary motor.
CAUTION
Slow speed running is not intended for continuous operation due to reduced motor cooling.
Jog operation causes the motor to heat faster than the rate calculated by the motor thermal model.
If you are using jog, install a motor thermistor or allow sufficient restart delay (parameter 5A)
7.8. 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 ≤ 600 VAC.
