Parameter Reference
Parameter Name
No.
PMAC Back Emf Const KE
0560
Set the motor's Back EMF line to line, rms value (Ke, Volts rms per 1000 rpm)
PMAC Winding
0561
Resistance
Set the motor's resistance, line to line at 25 °C.
PMAC Winding
0562
Inductance
Set the motor's inductance line to line at maximum current. This parameter is used within the current loop and is related to the overall
proportional gain.
PMAC Torque Const KT
0563
Torque constant (Kt, Nm/A rms).
This parameter is used to compute the current demand given a torque demand :
Torque demand = KT x Current demand
PMAC Motor Inertia
0564
Rotor inertia of motor.
PMAC Therm Time Const
0565
Copper Thermal Time constant(s). If not known set to 300s.
This parameter is used for the motor thermal protection : Refer to Motor Load module.
It represents the time needed to reach 63% of the rated load of the motor if 100% of the rated current is applied to the motor (typical
time constant of a first order low pass filter).
