The switching frequency for SLSM-PSM remains fixed at 8 kHz. However, the customer should be able to choose between an 8-kHz 3-switch configuration and an 8-kHz 2-switch configuration.
Description of the behavior:
The deceleration to a standstill does not function properly in SLSM-PSM. The motor begins to oscillate at approximately 3.7 Hz.
Changing the switching frequency from 8 kHz to 2 kHz and back causes interference when switching from the fundamental wave model to HF mode.
