Local variable definition
Inputs
Any one of the hardware limit switches is active (NO)
1)
2)
NO: Normally Open
NC: Normally Closed
1)
This input can come from signal OVlmt of subroutine 40, and triggers emergency stop when the hardware limit appears.
2)
Before the drive system disables the control enable signal, the PLC detects the spindle stop signal from NCK to ensure
that the spindle has stopped.
NC being in the cyclic state and able to enable the drive
Relevant PLC machine data
14512 [18].4
Spindle has an external stop signal
Spindle has no external stop signal
14512 [21].1
Set I0.0 to I2.7/Q0.0 to Q1.7 as the standard I/O wiring in the default PLC
Set I6.0 to I8.7/Q4.0 to Q5.7 as the standard I/O wiring in the default PLC
Example for calling subroutine 33
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
