C043 (C086, C129) Current Limit While accelerating
C043 (Motor 1)
C086 (Motor 2)
C129 (Motor 3)
Range
0 ÷ 400 (*)
0: Disabled
1.0% ÷ Min[Ipeak inverter/Imot, 400.0%]
Default
150%
Level
BASIC (C043); ADVANCED (C086, C129)
Address
1043, 1086, 1129
Control
IFD
Function
This parameter defines the current limit while accelerating; it is expressed as a
percentage of the rated current of the selected motor.
No limit is applied if this parameter is set to 0: Disabled.
(*) The maximum allowable value depends on the drive size.
C044 (C087, C130) Current Limit at Constant Rpm
C044 (Motor 1)
C087 (Motor 2)
C130 (Motor 3)
Range
0 ÷ 400 (*)
0: Disabled
1.0% ÷ Min[[Ipeak inverter/Imot, 400.0%]
Default
150%
Level
BASIC (C044); ADVANCED (C087, C130)
Address
1044, 1087, 1130
Control
IFD
Function
This parameter defines the current limit at constant rpm; it is expressed as a
percentage of the rated current of the selected motor.
No limit is applied if this parameter is set to 0: Disabled.
(*) The maximum allowable value depends on the drive size.
C045 (C088, C131) Current Limit while Decelerating
C045 (Motor 1)
C088 (Motor 2)
C131 (Motor 3)
Range

Address
1045, 1088, 1131
Control
IFD
Function
This parameter defines the current limit while decelerating; it is expressed as a
percentage of the rated current of the selected motor.
No limit is applied if this parameter is set to 0: Disabled.
(*) The maximum allowable value depends on the drive size.
C046 (C089, C132) Current Limit Decrease in Field weakening
C046 (Motor 1)
C089 (Motor 2)
C132 (Motor 3)
Range
0 ÷ 1
0: Disabled
1: Enabled
Default
0
0: Disabled
Level
ADVANCED
Address
1046, 1089, 1132
Control
IFD
Function
This parameter enables the current limit decrease function in field weakening.
The current limit is multiplied by the ratio between the motor rated torque and the
frequency forced to the drive:
limit = current limit being used * (Fmot/ Fout).
