13.13.22 FC 18: SpinCtrl spindle control
Function
FC SpinCtrl can be used to control spindles and axes from the PLC.

This block supports the following functions:
• Position spindle
• Rotate spindle
• Oscillate spindle
• Indexing axes
• Positioning axes
Each function is activated by the positive edge of the appropriate initiation signal (start, stop). This signal must
remain in the logic "1" state until the function has been acknowledged positively or negatively by InPos="1" or
Error = "1". The output parameters are deleted when the relevant trigger signal is reset and the function
terminated.
To be able to control an axis or spindle via the PLC, it must be activated for the PLC. This can, for example, be
achieved by calling the FC "SpinCtrl" with activation of the "Start" or "Stop" parameter. In this case, the FC
"SpinCtrl" requests control over the spindle/axis from the NC.
