Speed setpoint matching

In the case of speed setpoint comparison, the NC is informed, which speed setpoint
corresponds to which motor speed in the drive, for parameterizing the axial control and
monitoring. Speed setpoint matching can be performed automatically or manually.
Automatic adjustment
It is possible to perform automatic speed setpoint adjustment if the drive supports acyclic
services on the PROFIBUS-DP (standard for SINAMICS).
Acyclic services on the PROFIBUS-DP are supported
if in the following machine data the value "0" is entered:
● MD32250 RATED_OUTVAL (rated output voltage) [%]
During start-up of the NCK, speed setpoint matching between the NCK and the drive is then
performed automatically.
The SINAMICS parameter "Reference speed" p2000 may not be changed during operation
of the control with the drive.
Note
If automatic speed setpoint matching fails for one axis, the following message is output on a
traverse request for this axis:
• Message: "Wait, axis enable missing"
This axis and any axes that interpolate with it are not traversed.
Manual comparison
The speed setpoint alignment (interface normalization) is specified in the following machine
data:
● MD32250 RATED_OUTVAL (rated output voltage) [%]
● MD32260 RATED_VELO (rated motor speed)
If a non-zero value is entered into the following machine data, the NCK assumes that speed
setpoint matching will be performed manually.
● MD32250 RATED_OUTVAL (rated output voltage) [%]
Note
The maximum upper limit for the speed setpoint is set in machine data
• MD36210 CTRLOUT_LIMIT (maximum speed setpoint) [%]
