Parameter 14-05 PWM Generation
Table 706: Parameter 14-05 PWM Generation
14-05 PWM Generation
Default value: [0] Standard
Parameter type: Option
Setup: All setups
Conversion index: -
Data type: Uint8
Change during operation: True
Use this parameter in VVC+ and U/f mode only. When running with low ratio between switch frequency and output frequency (es-
pecially close to or <10:1), it is possible to improve the resolution of the PWM modulation and optimize the output voltage.

Standard
Use this setting for standard motors.
[1]
Double update
Updates the PWM pattern twice per switch period. Select this option to achieve a more optimal sinus-
wave and slight increase of the output voltage.
