Note
If a Power Module Blocksize is connected to a Control Unit, the sampling times of all vector
drives are set according to the rules for Power Modules Blocksize (only 250 µs or 500 µs
possible).

Setting the pulse frequency

The sampling times for the following functions are set by selecting the appropriate values in
p0112 for the closed-loop control configuration in µs and are copied to p0115[0...6]
depending on the performance levels required:
● Current controller (p0115[0])
● Speed controller (p0115[1])
● Flux controller (p0115[2])
● Setpoint channel (p0115[3])
● Position controller (p0115[4])
● Positioner (p0115[5])
● Technology controller (p0115[6])
The performance levels range from xLow to xHigh. Details of how to set the sampling times
are given in the SINAMICS S120/S150 List Manual.
