Initial Start Time
Select the Initial Start 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 Initial Start Time does not control the time the motor will
take to reach full speed.
1.
Set the Initial Start 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
1
) then stop
the motor.
5.
Set Initial Start Time = t
1
.
NOTE
The Initial Start Time must be long enough for the motor to
reach full speed before the soft starter enters bypass mode.
Soft Stop Time
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.
