The integral factor of the speed controller is adjusted in these parameters (see chapter
7.2 ÑStart-upì).

Factory setting:
The switching frequency with which the power modules are clocked can be changed
depending on the application. The employed power stage determines the maximum
switching frequency as well as the factory setting (see manual: part2). Refer to following
list to learn about influences and effects of the switching frequency.
low switching frequency
Åless inverter heating
Åless discharge current
Åless switching losses
Åless radio interferences
Åimproved concentricity with low speed
(only controlled!)
Adjustment range (dep. on power circuit): 2 / 4 / 8 / 12 / 16 kHz
Factory setting:
Note:
At switching frequencies above 4 kHz pay absolute attention to the max.
motor line length in the technical data of the chapter 2.1.
