Select the start ramp time (B).

The start ramp defines how long the soft starter will

take to increase voltage from the initial start voltage to

full voltage.

The start ramp time does not control the time the

motor will take to reach full speed.

1. Set the start ramp time to 20 seconds.

2. Set the initial start voltage as required for the

application.

3. Attach a current monitoring device to output T1.

4. Start the motor under normal load conditions.

Record the time required for the measured current

to fall to (or below) the motor's rated full load

current (t

) then stop the motor.

5. Set start ramp time = t

NOTE

The start ramp time must be long enough

for the motor to reach full speed before the

soft starter enters bypass mode.

Select the soft stop ramp time (C).

Soft stop extends the time soft starter takes to reduce

voltage to zero.

The ramp time does not control the time the motor will

take to stop completely.
