OPERATION
710-14888-00C EMX4i User Manual
59
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.
Parameters 2H and 3J
Jog Torque
control how much of the maximum available jog
torque the soft starter will apply to the motor.
NOTE
Torque settings above 50% may cause increased shaft vibration.

Inside Delta Operation
When connecting in inside delta, enter the motor full load current (FLC) for
parameter 1B. The EMX4i will automatically detect whether the motor is connected
in-line or inside delta and will calculate the correct inside delta current level.
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 2J
Stop
Time
is >0 secs.
If parameter 2J is set to 0 secs the starter performs a coast
to stop.
Jog
The starter issues a warning with the error message
Unsupported option.
DC Brake
The starter performs a coast to stop.
Soft 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, the EMX4i will not detect phase loss on T2
during run.
NOTE
If the starter is not correctly detecting the motor connection, use parameter
20F
