Example for calling subroutine 33
3.10 Subroutine 37 - MCP_NCK (MCP and HMI signal processing)
Purpose
Subroutine 37 is used to transfer the interface signals from the MCP and HMI to the NCK
interfaces, and thus to activate the specific operating mode and control sequences. It has the
following main functions:
● Selecting specific operating mode
● Selecting override
● Transferring signals from the HMI to NCK interfaces (for instance, program control,
handwheel, etc.)
● Controlling the axis traversing signal according to the PLC machine data
