Special features of modulo rotary axes
Modulo rotary axes can approach the position in both directions. The shortest path (DC) is not
observed during the travel.
Features of spindles
A spindle changes to the positioning mode on actuating the "Position travel in JOG" function.
The closed loop position control is active and the axis can be traversed to the position.
If no zero mark is detected the alarm message in the axis operation is output:
Alarm 17810 "Channel %1 Axis %2 not referenced"
As a spindle must also be a modulo rotary axis at all times, the same conditions apply for
direction observation as for modulo rotary axes (refer to the paragraph "Features of modulo
rotary axes")

Parameter setting

Consideration of axial frames and tool length compensation
The consideration of axial frames and, if an axis is configured as geometry axis, the tool length
compensation, depends on the setting of bit 1 in the machine data:
MD10735 $MN_JOG_MODE_MASK (settings for the JOG mode)
Bit
1
Retraction in the opposite direction
The behavior when retracting from a position in the opposite direction depends on the setting
of bit 2 in the machine data:
MD10735 $MN_JOG_MODE_MASK (settings for the JOG mode)
Bit
2
Position to be approached
The position to be approached is entered in the setting data:
