23.6 Activating a coupling

23.6 Activating a coupling
The type of activation for a master-slave coupling is defined in the following machine data:
MD37262 MS_COUPLING_ALWAYS_ACTIVE
Depending on the machine configuration, a distinction is made between a permanent and a
temporary master-slave coupling.
Only a temporary master-slave coupling (MD37262 = 0) that has been configured can be
closed and disconnected using the axial PLC interface signal "Master/slave on"
(V380x 5000.7) or within a part program using the following commands:
● MASLON(slave axis1)
● MASLOF(slave axis1)
The setpoint status of the coupling always corresponds to the last specification made.
The current coupling status can be read out in the slave axis via PLC interface signal
"Master/slave coupling active" (V390x 5000.7).
In the part program and from the synchronized actions, the current coupling status can be
output via the system variable of the slave axis $AA_MASL_STAT.
Spindle coupling
The MASLOFS(Slv1) instruction can be used to disconnect the coupling in the same way as
MASLOF and decelerate the slave spindle automatically.
Note
A permanent coupling (MD37262 = 1) does not require explicit activation.
Control system response
The control response to POWER ON, operating mode changes, RESET, block searches,
and REPOS is as follows:
● A master-slave coupling activated via the PLC or
