Switching frequency 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!)

high switching frequency

Åless noise development

Åimproved sine-wave simulation

Åless motor losses

Åimproved controller characteristics

Adjustment range (dep. on power circuit): 2 / 4 / 8 / 12 / 16 kHz

Factory setting: depending on power circuit

Note: ENTER-Parameter

KI speed The integral factor of the speed controller is adjusted in these parameters (see chapter

7.2 ÑStart-upì).

Adjustment range: 0...32767

Resolution: 1

Factory setting: 100

KP speed

The proportional factor of the speed controller is adjusted in these parameters (see

chapter 7.2 ÑStart-upì).

Adjustment range: 0...32767

Resolution: 1

Factory setting: 300

At switching frequencies above 4 kHz pay absolute attention to the max.

motor line length in the technical data of the chapter 2.1.
