Current Limit Setting - WEG SSW-08 Manual Del Usuario

NOTE!
The Initial Voltage trimpot has an initial voltage setting function only when the kind of
control is programmed to start with a voltage ramp.

4.4 CURRENT LIMIT SETTING

This setting defines the maximum limit of the current from phases R and S during motor starting
in percentage of the nominal current of the Soft-Starter.
If the current limit is reached during the start of the motor, Soft-Starter SSW-08 will maintain the
current at this limit until the motor reaches nominal speed.
If the current limit is not reached, the motor will start immediately.
The current limitation should be set to a level that the motor acceleration can be observed,
otherwise the motor will not start.
NOTE!
If at the end of the acceleration ramp (set at the Trimpot Acceleration Time), full voltage
is not reached, a start timeout Fault will be shown. This fault is indicated through the
Fault LED flashing twice with the Ready LED on.
The trimpot Current Limit has a Current Limit setting function only when the kind of
control is programmed to start with a Current Limit.
