MD21158 $MC_JOG_JERK_ORI [<orientation axis>]
For MD21158 to take effect, the channel-specific jerk limitation for the manual traversing of
orientation axes must be enabled via the following machine data:
MD21159 $MC_JOG_JERK_ORI_ENABLE == TRUE
Alarms
Alarm 20060
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 manually traverse it as a geometry axis in JOG mode.
Alarm 20062
Alarm 20062, "Axis already active", is triggered in the case that a geometry axis/orientation
axis is manually traversed 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 this
coordinate system is traversed in JOG mode with the traversing keys.

Approaching a fixed point in JOG
4.9.1
Function
The machine user can use the "Approaching fixed point in JOG" function to approach axis
positions defined through machine data by actuating the traverse keys of the machine control
table. The traveling axis comes to a standstill automatically on reaching the defined fixed point.
Note
Approaching a fixed point with G75
The process for approaching defined fixed points can also be activated from the part program
using the G75 command.
For more information on fixed point approach with G75 please refer to:

Programming Manual, Fundamentals; Section: "Additional commands" > "Approach fixed point
(G75)".
Applications
Typical applications are, for example:
● Approaching a basic position before starting an NC program.
● Travel towards tool change points, loading points and pallet change points.
