Signal : F0.4
Symbol : SPL
Description : Feed hold signal
Detail : CNC will inform the PLC that feed hold is given by user.
The F0.4 (SPL) flag is typically activated when the operator presses the feed hold button on the CNC panel to temporarily stop the machine’s motion. In response, the PLC would typically:
- Pause or hold the feed motion of the machine.
- Stop all movements related to the current machining operation (e.g., cutting, positioning).
- Allow the operator to inspect or adjust the machine settings.
- Provide the option to resume the feed or perform further actions when the operator deactivates the feed hold.

Signal : F0.0
Symbol : RWD
Description : Rewind signal
Detail : CNC will inform the PLC that reset and rewind command is given by user.
When the F0.0 (RWD) signal is activated, the PLC is expected to initiate actions that are defined for a reset and rewind operation. These actions might include:
- Clearing or resetting certain program variables or flags.
- Rewinding the process or machine to a predefined home position.
- Initiating a process restart or safe operation mode depending on the machine’s configuration.
