DETAILED PARAMETER DESCRIPTION
P11- Calculation
example for
setting of current
limitation
IN of the switch = 170A
IN of the motor = 140A
ILIM=250% of the IN of the motor
2.5x 140A =350A
P11=205% of the IN of the switch =2.5x IN of the motor.
2) Within the motor delta connection
 To limit the current at 2.5 x IN of the motor:
1) Standard Connection
