Procedure
Procedure for position travel in JOG:
1. Selection of JOG mode
2. Specification of the position to be approached
3. Enabling the "Position travel in JOG" function
4. Traversing of the machine axis with traverse keys or handwheel
Specification of the position to be approached
The position to be approached is entered in the setting data:
SD43320 $SA_JOG_POSITION (JOG position)
Activating the function
The PLC sets the interface signal after the "Position travel in JOG" function has been selected:
DB31, ... DBX13.3 (JOG travel to position)
The NC confirms the activation with the interface signal as soon as the function is effective:
DB31, ... DBX75.6 (JOG JOG travel to position active)
Note
Activation is not possible:
● during an NCK reset
● In case of impending emergency stop
● During processing of an ASUP
● if the "approaching fixed point JOG" function is already activated
No alarm message occurs. Delayed activation takes place after closure or after
acknowledgement of the active function.
Sequence
Approaching the position is started with the traverse keys or the handwheel.
The axis traverses until it comes to an automatic standstill at the position to be approached.
When the position is reached with "Exact stop fine", the following NC/PLC interface signal is
output:
DB31, ... DBX75.7 (JOG position reached)
Approach a different position
If the content of the setting data SD43320 is changed while approaching a position, then the
axis movement is canceled and the following alarm is output:
