Options 0“Disabled”
1“Reduce CLim”
2 “Reduce PWM”
3 “Both-PWM 1st” (Default)
A496 [IR Voltage Drop] Related Parameter(s): P040
Value of volts dropped across the resistance of the motor stator (autotune) for induction motor.
Values Default: Based on Drive Rating
Min/Max: 0.0/600.0VAC
Display: 0.1VAC
A497 [Flux Current Ref] Related Parameter(s): P040
This is the current necessary for full motor flux. The value should be set to the full speed no-load current of the motor.
Values Default: Based on Drive Rating
Min/Max: 0.00/(Drive Rated Amps x 1.4)
Display: 0.01 A
A498 [Motor Rr]
PowerFlex 525 only.
Rotor resistance of induction motor. The value of this parameter will populate when a full rotate tune is performed.
Values Default: Based on Drive Rating
Min/Max: 0.00/655.35 ohm
Display: 0.01 ohm
PF 525
A499 [Motor Lm]
PowerFlex 525 only.
Mutual Inductance of induction motor. The value of this parameter will populate when a full rotate tune is performed.
