4.4 CURRENT LIMIT
SETTING
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.
This setting defines the maximum limit of the current 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-07 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.

NOTES!
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.
