Description The Maximum Current 1 parameter is set as a percentage of the motor FLA parameter setting. The
Maximum Current 1 parameter performs two functions. It sets the current level for the end of the
ramp profile. It also sets the maximum current that is allowed to reach the motor after the ramp is
completed.
If the ramp time expires before the motor has reached full speed, the starter holds the current at the
maximum current level until the UTS timer expires, the motor reaches full speed, or the overload
trips.
Typically, the maximum current is set to 600% unless the power system or load dictates the setting of
a lower maximum current.
