Alarms
Alarm 20062, "Axis already active", is triggered in the case of geometry-axis manual travel
under the following conditions:
● The axis is already being traversed in JOG mode via the axial PLC interface.
● A frame for a rotated coordinate system is already active and another geometry axis in
If the axis is not defined as a geometry axis, alarm 20060, "Axis cannot be traversed as a
geometry axis", is output if you attempt to traverse it as a geometry axis in JOG mode.

Special features of spindle manual travel

Spindle manual travel
Spindles can also be traversed manually in JOG mode. Essentially, the same conditions
apply as for manual travel of axes. Spindles can be traversed in JOG mode using the
traversing keys continuously or incrementally, in jog or continuous mode, or using the
handwheel. The function is selected and activated via the axis-/spindle-specific PLC
interface in the same way as for the machine axes. The axis-specific machine data also
apply to the spindles.
Spindle mode
Spindle manual travel is possible in positioning mode (spindle is in position control) or in
open-loop control mode.
JOG velocity
The velocity used for spindle manual travel can be defined as follows:
● Using general setting data
or
● Using machine data
The maximum speeds for the active gear stage also apply when spindles are traversed in
JOG mode.
