Coupling cascading

Coupling cascades
The coupling modules can be connected in series. The following axis/spindle of a coupling
module then becomes the leading axis/spindle of another coupling module. This results in a
coupling cascade.

CPMALARM is a bit-coded CP keyword for suppressing special coupling-
related alarm outputs.
The bit combination operators B_OR, B_AND, B_NOT, and B_XOR can be
used to set individual bits.
Bit Value Meaning
0 = 1 Alarm 16772 is suppressed.
1 = 1 Alarm 16773 is suppressed.
2 = 1 Alarm 16774 is suppressed.
3 = 1 Alarm 22012 is suppressed.
4 = 1 Alarm 22013 is suppressed.
5 = 1 Alarm 22014 is suppressed.
6 = 1 Alarm 22015 is suppressed.
7 = 1 Alarm 22016 is suppressed.
8 = 1 Alarm 22025 is suppressed.
9 = 1 Alarm 22026 is suppressed.
10 = 1 Alarm 22040 is suppressed for the cyclic check in
case of previously activated position control for fol‐
lowing and leading spindles.
11 = 1 Alarm 16771 is suppressed.
12 - 31 Reserved.
The default values correspond to the settings in the machine data:
● MD11410 $MN_SUPPRESS_ALARM_MASK (mask for suppressing
special alarm outputs)
● MD11415 $MN_SUPPRESS_ALARM_MASK_2 (suppress alarm
outputs)
Comment
; The 22025 and 22026 alarms are suppressed for the cou-
pling of the X2 following axis.
