Beispiel:
given: fDIG.SET
max
= 100 kHz
nmax= 3000 rpm
required: encoder constant C026
encoder setting C027
100 kHz = 100.000 increments/s
3000 rpm = 50rps
C 026 =
100.000 increments / s
50 / s
= 2000 increments/revolution
Selectable are 512, 1024, 2048, 4096 increments/revolution
C026 = 2048 is chosen
C027 = 2048/2000 = 1,024
C027 = 1,024 is to adjust.
3.2. Input of motor nameplate data
To calculate the excitation and torque generating components of
the current vector, it is necessary to enter the motor nameplate
data correctly.
This is only possible if the controller is inhibited, i.e. RFR ENABLE
open, or the STP key pressed.
•
C081 Rated motor power
This parameter is only required for automation module
applications to calculate the absolute reference for the torque.
The rated motor power of the Lenze servo motor, which is best
adapted to the axis module, is factory-set.
