Position offsets
NC program
Linking of a logical axis to the physical ones can be modified in the running program. After suspension of axis output, the axes can be moved by another channel.
After returning to the original channel, the assumed and the actual position setpoints may deviated from one another. This position offset is displayed for the physical axis and is deleted each time the program is restarted.
Offset = command position (of active link)active position
Example: Axis 1 of 1st channel and axis 2001 of 2nd channel are linked to same physical axis. In each channel an different MDI is started and channel are suspended one after another.
Channel 1: X100 Command position | Channel 2: X-50 Command position | Real position | Offset |
0 -> 50 |
| 0 -> 50 | 0 |
| 50 -> 15 | 50 -> 15 | 0 |
50 -> 80 |
| 15 -> 45 | 35 |
| 15 -> 0 | 45 -> 30 | -30 |
