Figure 12. Adjust Time and Torque
How to Adjust Time and Torque, Figure 12
Control of the motor torque is achieved by acting on the motor
voltage.The motor speed depends on the torque produced by
the motor and the load on the motor shaft. A motor with little or
no load will reach full speed before the voltage has reached its
maximum value.
NOTE: The soft start controller will read time and torque set-

tings in the OFF state. Repeated starts may trip the
motor protection relay. DO NOT set the rotary
switches in between positions. This corrupts the time
and torque adjustment. Use screwdriver 2 mm x
0.5 mm.
Setting/Adjustment
Set the Ramp-Up switch to maximum.
Set the Ramp-Down switch to minimum.
Set the Initial Torque switch to minimum.
Apply control signal for a few seconds. If the load does not
rotate immediately, increment the Initial Torque and try
again. Repeat until the load starts to rotate immediately on
startup.
Adjust Ramp-Up time to the estimated start time (the
scale is in seconds) and start the motor.
Decrease the Ramp-Up time until mechanical surge is
observed during start.
Increase the time one step to eliminate the surge.

Kick Start/Break Loose
If it is not possible to reach a time sufficient for the application,
it may be necessary to kick start the load.

Setting/Adjustment
Set the Ramp-Up switch to maximum.
Set the Ramp-Down switch to minimum.
Set the Initial Torque switch to minimum kick
start torque.
Apply control signal for a few seconds. If the load stops
right after the 200ms “kick”, increment the Initial Torque
and try again. Repeat until the load continues to rotate
after the “kick”.
Adjust Ramp-Up time to the desired start time (the scale is
in seconds) and start the motor.
Setting/Adjustment
Set the Ramp-Down switch to maximum.
Switch off the control voltage and observe any mechanical
surges on the load. If there are none, decrement Ramp-
Down switch and try again. Repeat until mechanical surge
on the load is observed.
Increase the time one step to eliminate the surge.
