Parameter Setting - Siemens SINUMERIK 840D Function Manual

● For active tool radius compensation and internal machining: Positions too close to center of
circle
● For active tool radius compensation and circle segment machining: Positions too close to
segment borders
Changes to the setting data
Changes in the function-relevant setting data SD42690 to SD42694 that are made during an
active JOG motion only take effect after ending the active JOG motion by triggering a new JOG
motion.
Note
To ensure that changes in the setting data take effect more quickly, the machine operator can
proceed as follows:
1. Cancel the current traverse movement with residual distance deletion.
2. Change setting data.
3. Restart the JOG motion.
Abort/deactivation
If during a JOG motion the function "Circular travel in JOG" is deactivated (DB21, ... DBX30.6
= 0), then the JOG motion is canceled and an alarm is output.
Note
To avoid the alarm message, the machine user should proceed as follows:
1. Cancel the current traverse movement with residual distance deletion.
2. Deactivating the function after axis standstill.

Parameter setting

Traversing direction of the second geometry axis
The traversing direction of the second geometry axis can be set via the following machine data:

Value Meaning
0 Traversing of the 2nd geometry axis of the active plane to plus increases the radius,
traversing to minus decreases the radius. The traversing movement is independent of
0
whether internal or external machining is active.
