18.1 PROGRAMMING THE MECHANICAL LOCKING SYS-
TEM.
The locking procedure is a 3−step procedure:
1) Position the spindle at the desired degree by using the function Mx19 Q..
2) Deactivate the servo−mechanism of the motor S1 or S4 by using the func-
tion M800 P1=−..., before engaging the lock.
3) Engage the compressed air lock by using the functions M831 or M841.
Note:
The spindle has to be de−servoed to prevent stress forces on the motor
if the toothed disk has not been correctly adjusted. If these stress
forces are too high, a NC alarm may be triggered.

Line 7/10: Mandatory timeout of 0.5 sec. to allow the lock to be correctly
engaged.
Line 2/4: Timeouts to be programmed according to the kind of machine.
