Response On Activation/Deactivation - Siemens SINUMERIK 840D sl Function Manual

$AA_MASL_STAT[<slave axis>]
Value
> 0
NC/PLC interface signal
The current coupling state of a slave axis can be read using the following axis-specific NC/PLC
interface signal:
DB31, ... DBX96.7 (master/slave coupling active)
Setpoint state
Requests to switch on/off a master-slave coupling (NC/PLC interface signal and/or program
commands) that consecutively follow one another mutually overwrite one another. The
effective setpoint state results from the last chronological request (see Section "Response on
activation/deactivation (Page 617)").

Response on activation/deactivation

On/off at standstill (axis)
A request to switch on/off the coupling only becomes effective when the master and slave axis
are at a standstill (zero speed):
DB31, ... DBX61.4 == 1 (axis/spindle stationary)
In this case, the coupled axes must be in the closed-loop controlled mode.
