Variant 1: Motor calculation
l
Enter the motor data
The motor data relevant to the calculation must be entered manually from the
data sheet.
l
Click on “Start calculation”.
l
If the moment of inertia of the motor
P 461 - Mot_J
is not known, a value
roughly corresponding to the motor's moment of inertia must be applied.
l
The calculation process can be monitored in the Moog D

Calculation of operating point: Flux
P 462 - MOT_FLUXNom
l
Calculation of: current, speed and position control parameters

All existing motor parameters are overwritten.
Calculated values
l
Flux settings (including for torque constant)
l
Control settings for current controller: the current controller is dimensioned
based on the actual switching frequency set.
l
Speed controller and position controller gain: here a moderately stiff
mechanism and mass inertia matching from load to motor with a ratio of 1:1 is
to be assumed.
l
V/F characteristic
