Speed setpoint output
Control direction and travel direction of the feed axes
You must determine the travel direction of the feed axis before starting work.
Control direction
Before the position control is started up, the speed controller and current controller of the
drive must be started up and optimized.
Travel direction
Machine data:
MD32100 $MA_AX_MOTION_DIR (travel direction)
can be used to reverse the direction of movement of the axis,
without affecting the control direction of the position control.
Speed setpoint adjustment
SINUMERIK 840D/810D
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. This comparison is carried out automatically.
SINUMERIK 840D with PROFIBUS DP
It is necessary to change machine data:
MD32250 $MA_RATED_OUTVAL[n] (rated output voltage)
from 80% to 0%, corresponding to value "0", for PROFIBUS DP drives with automatic
comparison of speed setpoint scaling.
This value must also be set in the case of adjustment in the NC.
Alternatively for PROFIBUS-DP drives, manual speed setpoint comparison is also possible.
•
Manual comparison
A value other than zero is entered in machine data:
MD32250 $MA_RATED_OUTVAL.
