Description The Initial Current 1 parameter is set as a percentage of the motor FLA parameter setting. The Initial
Current 1 parameter sets the current that is initially supplied to the motor when a start is commanded.
The initial current should be set to the level that allows the motor to begin rotating within a couple of
seconds of receiving a start command.
To adjust the initial current setting, give the starter a run command. Observe the motor to see how
long it takes before it begins rotating and then stop the unit. For every second that the motor doesn’t
rotate, increase the initial current by 20%. Typical loads require an initial current in the range of 50%
to 175%.
If the motor does not rotate within a few seconds after a start command, the initial current should be
increased. If the motor takes off too quickly after a start command, the initial current should be
decreased.
The Initial Current 1 parameter must be set to a value that is lower than the Maximum Current 1
parameter setting.
