PNO Parameter Descriptions
0563
PMAC Torque Const KT
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
0564
PMAC Motor Inertia
Rotor inertia of motor.
0565
PMAC Therm Time Const
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).
1387
PMAC Base Volt
Rated motor rated voltage in Volt rms
