Call example
CALL FC 24 (
With these parameter settings, the signals are sent to the 1st mode group, the 1st channel
and all axes. In addition, the spindle override is transferred to the 4th axis/spindle interface.
The feed hold signal is passed to bit memory 22.0 and the spindle stop signal to data block
DB2, data bit 151.0. The spindle direction feedback signal supplied via parameter
"SpindleDir" can be used as a direction input for an additional FC 18 call.
2.12.26 FC 25: MCP_IFT transfer of MCP/OP signals to interface
Description of Functions
With the FC MCP_IFM (M-variant) from the machine control panel a range of 19 inch e.g.
MCP 483 are transferred to the corresponding signals of the NCK-/PLC-interface:
• Mode groups
• Direction keys of four axes
• WCS/MCS switchover commands
• Overrides
• Key-operated switch
In the basic program (FC 2), handwheel selections, modes and other operating signals
continue to be transferred from the operator panel front or HMI to the NCK/PLC interface so
that the modes support selection from the MCP or HMI.
Transfer of HMI signals to the interface can be deactivated by setting the value of the
parameter "MMCToIF" to "FALSE" in FB 1 (DB 7).
