On the CC 422 higher PWM frequencies (> 5000 Hz) can be set for controller groups with
PWM frequency
MP 2180.x. This means, that not all PWM outputs of a controller group can be used.
With the respective configuration individual PWM outputs are not active!
Different PWM frequencies in MP 2180.x can be assigned also to the CC 424 (B).
There are three fundamental PWM frequencies: 3333 Hz, 4000 Hz and 5000 Hz. A control loop
can be operated at the fundamental PWM frequency or at double (6666 Hz, 8000 Hz und 10000
Hz) this frequency.
If a control loop is operated at double the fundamental PWM frequency, the current controller
cycle time is halved. However, this is possible only with double-speed control loops.
With the respective configuration individual PWM outputs are not active!

Note
The connectors as of X57 can be assigned as of MP 120.6 (7th axis), but not those before!
Note
On the CC 424 (B) with 8 and with 14 control loops, X57/X80 und X58/X81 are still located
on the main DCB.
