HEIDENHAIN MANUALPLUS 620 - 6.19.3 PWM frequencies with the CC 61 xx

1048 HEIDENHAIN Technical Manual MANUALplus 620
6.19.3 PWM frequencies with the CC 61xx
In MP_ampPwmFreq, you assign different PWM frequencies to the CC 61xx
controller groups.
There are three fundamental PWM frequencies: 3.333 kHz, 4 kHz and 5 kHz.
A control loop is operated at the fundamental PWM frequency or at double the
fundamental PWM frequency (6.666 kHz, 8 kHz, 10 kHz).
The same PWM frequency must be assigned to both PWM outputs of a
controller group with MP_ampPwmFreq. Otherwise, the DSP error message
C440 PWM frequency <axis> incorrect will appear.
 Controller group 1: X51, X52
 Controller group 2: X53, X54
 Controller group 3: X55, X56
