Table 233: Option:
[0]
Ran3
3 kHz true random PWM (white noise modulation).
[1]
Ran5
5 kHz true random PWM (white noise modulation).
[2]
2.0 kHz
Select 2.0 kHz as the inverter switching frequency.
[3]
3.0 kHz
Select 3.0 kHz as the inverter switching frequency.
[4]
4.0 kHz
Select 4.0 kHz as the inverter switching frequency.
[5]
5.0 kHz
Select 5.0 kHz as the inverter switching frequency.
[6]
6.0 kHz
Select 6.0 kHz as the inverter switching frequency.
[7]
8.0 kHz

14-03 Overmodulation
Default value: [0] Off
Parameter type: Option
2-setup: All setups
Conversion index: -
Data type: u_int8
Change during operation: False
Table 234: Option:
[0]
Off
Select no overmodulation of the output voltage to avoid torque ripple on the motor shaft.
[1]
On
Select [1] On to obtain extra DC-link voltage and torque on the motor shaft.
14-07 Dead Time Compensation Level
Default value: Configuration dependent
Parameter type: Range
2-setup: All setups
Conversion index: 0
Data type: u_int8
Change during operation: False
Level of applied dead-time compensation in percentage. A high level (>90%) optimizes the dynamic motor response. A level 50–
90% is suitable for both motortorque- ripple minimization and motor dynamics. A 0 level turns off the dead-time compensation.
Table 235: Range:
Min: 0
Max: 100
Default value: Configuration dependent
14-08 Damping Gain Factor
Default value: Configuration dependent
Parameter type: Range
2-setup: All setups
Conversion index: 0
Data type: u_int8
Change during operation: True
Set the damping factor for DC-link voltage compensation. See parameter 14-51 DC-Link Voltage Compensation.
Table 236: Range:
Min: 0%
Max: 100%
Default value: Configuration dependent
