How to change the PWM frequency in MotionLab3?
In order to change the PWM frequency to use for commutation, you need to use the following register: 0x521 - Power stage frequency. It can take the following values which related to the different PWM frequencies available:
0 → 10 kHz
1 → 20 kHz
2 → 50 kHz
3 → 100 kHz
This register can be modified in either the Drive Explorer or Control widgets inside the MotionLab3 GUI.
