Speed setpoint smoothing
Signal state 0 or
edge change
1 → 0
No smoothing of the speed setpoint value is requested by the PLC.
Application
example(s)
With this interface signal, speed setpoint smoothing can - for example - be activated from the PLC
user program for a spindle during speed control to achieve smooth torque output. Speed setpoint
smoothing can therefore be deactivated when the spindle is in positioning mode.

Drive parameter set selection A, B, C
Edge evaluation: no Signal(s) updated: cyclic
Meaning With bit combinations A, B and C it is possible to select 8 different drive parameter sets for the
digital drives SIMODRIVE 611D/611U/SINUMERIK 810D.

The switchable drive parameters are as follows:
• Current setpoint filters (low-pass, band-stop); for adaptation to the mechanics
• Motor speed normalization
• Speed controller parameters
• Speed setpoint filter
• Speed monitoring data
As soon as the new drive parameter becomes effective, the drive signals this to the PLC using the
interface signals:
