Figure 10-21 Example for speed ranges for automatic gear stage selection (M40)
Speeds for conventional operation
The speeds of the spindle in conventional mode are entered in the machine data:
• MD32010 JOG_VELO_RAPID (rapid traverse in jog mode)
• MD32020 JOG_VELO (JOG axis velocity)
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.
