The integral factor of the speed controller is adjusted in these parameters
(see chapter 5 „Adjustment instruction speed controller").

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
• less inverter heating
• less discharge current
• less switching losses
• less radio interferences
Adjustment range (dep. on power circuit):
Factory setting
Note:
At switching frequencies above 4 kHz pay absolute attention
to the max. motor line length in the technical data of the power
circuit manual (Part 2).
