NC Commissioning with HMI Advanced
11.5 Axes and spindles
Speeds for conventional operation
The speeds of the spindle in conventional mode are entered in the following machine data:
● MD32010 $MA_JOG_VELO_RAPID (rapid traverse in jog mode)
● MD32020 $MA_JOG_VELO (axis velocity in JOG mode)
The direction of rotation is specified via the appropriate directional keys for the spindle on the
MCP.
Direction of rotation
The direction of rotation of a spindle corresponds to the traversing direction of an axis.
Setpoint matching
The speeds must be transferred with standardized values for the drive controller. The values
are scaled in the NC using the selected load gear and the appropriate drive parameter.
