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.

12.12.2 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)
