Slave axis
Configuration of salve axis
For gantry slave axes, bit 0x00020000 must be set in axis mode (P-AXIS-00015).
The following must also be configured for the slave axis:
- Axis number of master axis (P-AXIS-00070)
- Offset to master axis (P-AXIS-00073)
- Permitted resettable gantry error (P-AXIS-00072)
- Permitted non-resettable gantry error (P-AXIS-00071)
- Velocity to clear the position difference to the master axis (P-AXIS-00075)
A gantry slave axis may not be assigned to any NC channel (P-CHAN-00006, P-CHAN-00035).
Make sure that the following parameters for master and slave axes are identical:
- Modulo mode (P-AXIS-00018, P-AXIS-00015 Bit 0x00000004)
- Modulo range (P-AXIS-00126, P-AXIS-00127)
- Maximum acceleration (P-AXIS-00008)
- Emergency stop delay (P-AXIS-00003)
- CNC-controlled error reaction (P-AXIS-00254)
- Homing type (P-AXIS-00299)
- Delay after PLC watchdog error (P-AXIS-00367)
If these parameters are different, a warning is output at controller start-up and the master axis values are adopted.
Other axis parameters can be set in the slave axis as required.
