Assignment of control and status bits for CNC based homing (P-AXIS-00387)
To execute cnc controlled homing with drive support two control and status bits are necessary each. Its can be used the real time control and status bits in the drive control and status word or alternatively bits in the signal status and signal control word.
Variable name | Type | Permissible range | Axis type | Dimension |
cnc_homing_rt_bit_layout | UNS16 | 1 <cnc_homing_rt_bit_layout <16 | T, R | ---- |
