Auxiliary spindle controlled by PLC
7.10 Auxiliary spindle controlled by PLC
With this feature, the PLC can temporarily control the auxiliary spindle.
To do that, follow these steps:
1. Indicate from the PLC at the logic CNC input "SANALOAS" (R509) the amount of velocity
command to be applied to the drive for the auxiliary spindle.
On the other hand, set logic CNC input "PLCCNTAS" (M5056) high to indicate to the CNC that
from then on, it is going to be up to the PLC to control the velocity command output for the auxiliary
spindle.
2. From then on, the CNC outputs the velocity command voltage indicated by the PLC for the
auxiliary spindle as indicated at the CNC logic input "SANALOAS" (R509).
If the PLC changes the value of the "SANALOAS" input, the CNC will update its velocity
command output.
3. Once the operation has concluded, the control of the auxiliary spindle must be returned to the
CNC. To do that, the logic CNC input "PLCCNTAS" (M5056) must be set low.
