System variables

After a block search, the coupling status and associated axis positions can be adjusted
subsequently by means of a system ASUB (asynchronous subroutine) "PROGEVENT.SPF".
System variables $P_SEARCH_MASL_C, $P_SEARCH_MASL_D and $AA_MASL_STAT are
available for this purpose; they can be used to alter the positional offset between the coupled
axes and the coupling status:
Identifier
$P_SEARCH_MASLC[slave axis identifier]
$P_SEARCH_MASLD[slave axis identifier]
$AA_MASL_STAT[slave axis identifier]

TE3: Speed/torque coupling, master-slave
Description
Leading axis for speed setpoint coupling
Leading axis for torque distribution
Connection of torque control output
Activate torque compensatory control
Gain factor of torque compensatory controller
Reset time for torque compensatory controller
Limitation of torque compensatory control
Permanent master-slave coupling
Coupling characteristics of a spindle
Master-slave tension torque
Torque weighting of the slave axis
Master-slave velocity tolerance "coarse"
Master-slave velocity tolerance "fine"
Invert master-slave direction of travel
Meaning
This variable registers a change in the coupling state during the
SERUPRO block search.
This variable indicates the positional offset between the slave
and master axes at the instant the coupling was closed.
This variable indicates the current coupling state.
Value ≠ 0: "Master-slave coupling active"
In this case, it contains the current machine number of the
master axis and, if the NCU link is active (several operating panel
fronts and NCUs), also the NCU No. at the hundreds position.
Example: 201 for Axis 1 on NCU2.
