Parameter 14-05 PWM Generation
Table 706: Parameter 14-05 PWM Generation
14-05 PWM Generation
Default value: [0] Standard
Conversion index: -
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.

5.14.2 14-1* Mains On/Off
The following parameter is only available in FC 302:
-
Parameter 14-16 Kin. Back-up Gain
Parameters for configuring mains failure monitoring and handling. If a mains failure appears, the drive tries to continue in a control-
led way until the power in the DC link is exhausted.
Parameter 14-10 Mains Failure

Description
No change of the acoustic motor switching noise.
Select to reduce the acoustic noise from the motor.
Parameter type: Option
Data type: Uint8
Description
Use this setting for standard motors.
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.
Parameter type: Option
Data type: Uint8
