Variant 1: Motor calculation
Enter motor data
The motor data relevant to the calculation must be entered from the data
sheet.
Click on “Start calculation”.
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.
The calculation process can be monitored in the
Moog D
RIVE
A
DMINISTRATOR
via the menu, View, Messages.
Calculation of the working point: Flux
P 462 - MOT_FluxNom
,
P 340 - CON_
FM_Imag
.
Calculation of: Current, speed, and position control parameters
NOTE
All existing motor parameters are overwritten.
Calculated values
Flux settings (including for torque constant)
Control settings for current controller:
The current controller is dimensioned dependent on the switching frequency
setting.
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.
