FUNCTION:
The phase CT ratio supplied with the starter must be entered here. Enter only primary amperes. A 5 A second-
ary is assumed.
MOTOR TYPE:
Collector-Ring and Brushless

This setpoint is the motor-nameplate, full load current. It is related to the AC CT RTG setpoint. The minimum and
maximum current is determined by the formula below. Changes to the AC CT RTG setpoint may cause this set-
point to become invalid (out of range).

MOTOR TYPE:
Collector-Ring and Brushless
NOTE:
The value entered here affects the valid range of the motor locked rotor current (LR AMPS) setpoint.
LR AMPS:
ENTER to modify
FUNCTION:
This setpoint represents the motor locked rotor current and is related to the FL AMPS setpoint. The minimum
and maximum current is determined by the formula below. Changes to the AC CT RTG and/or the FL AMPS set-
points may cause this setpoint to become invalid (out of range).
minimum LR AMPS = 2 × FL AMPS, maximum LR AMPS = 12 × FL AMPS
