Setting The Sampling Times - Siemens SINAMICS S120 Function Manual

Basic information about the drive system
12.12 System sampling times
For p0092 = 1, the sampling times are pre-assigned so that isochronous operation together
with a control is possible. If isochronous operation is not possible due to incorrect sampling
time settings, then an appropriate message is output (A01223, A01224). Before the
automatic configuration, parameter p0092 must be set to "1" in order that the sampling times
are appropriately pre-set.
Note
Any change to the preset sampling times should only be performed by experts.

Setting the sampling times

Introduction
Setting the sampling times via p0112
The sampling times for:
● 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])
are set by selecting the appropriate values in p0112 for the closed-loop control configuration
and are copied to p0115[0...6] depending on the performance levels required. The
performance levels range from xLow to xHigh.
The sampling times are shown in the following table.
Table 12-22 For Active Infeed, the sampling time is set using p0112 (p0112 = 1 not for p0092 = 1)
p0112 p0115[0]
1: xLow 400
2: Low 250
3: Standard 125
4: High 125
5: xHigh 125
