Variant 1: Motor calculation
l
Enter the motor data
The motor data relevant to the calculation must be entered 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

l
Calculation of: current, speed and position control parameters

All existing motor parameters are overwritten.
Calculated values

Flux settings (including for torque constant)
l
Control settings for current controller:
The current controller is dimensioned dependent on the switching frequency
setting.
l
Speed controller and position controller gain:
In this, a moderately rigid mechanism and a 1:1 moment of inertia adjustment
from the load to the motor are to be assumed.
