P7 Maximum Motor Current 1 QST 07, CFN 04
LED Display LCD Display
Range 100 – 800 % of FLA (Default 600%)
Description The Maximum Motor Current 1 parameter is set as a percentage of the Motor FLA (P1 / QST 01) parameter
setting. This 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 either 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
or higher maximum current.
