Description

Output and Synchronization

The M and H functions are enabled for each CNC channel in the channel parameter list via their synchronization methods. For safety reasons, M and H functions cannot be used in the CNC program if a synchronization method is not specified (in this case, the CNC generates the message 20157).

There are the following possibilities of output to the PLC:

• No output
• Output before motion
• Output after event
• Output after motion

Output to the PLC (HLI) can take place in different ranges of the interface:

• Output in the channel range
• Output in the axis range

The following possibilities of synchronization with a motion to be executed are available:

• No synchronization
• Synchronization before motion
• Synchronization after motion
• Synchronization at the transition to the next motion block with machining feed rate ('late' synchronization implicit)
• Synchronization in the case of an explicit request ('late' synchronization explicit)
• Synchronization during a motion block (example: push-cut edge shaping)
