Maximum Current 1 CFN 04
LCD Display
Range 100 – 800 % of FLA (Default: 600%)
Description The Maximum Current 1 parameter is set as a percentage of the Motor FLA (QST 01) parameter setting and
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
maximum current.

Description
The Ramp Time 2 parameter sets the time it takes for the starter to allow the current to go from the initial
current to the maximum current when the second ramp is active. Refer to the Ramp Time 1 (QST 08 / CFN
02) for description of operation.
