Call example
CALL FC 24 (
FeedHold :=
SpindleHold :=
SpindleDir:=
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.
2.12.28 FC 25: MCP_IFT transfer of MCP/OP signals to interface
Description of functions
With FC MCP_IFT (T variants), the following are transferred from the machine control panel
(MCP) to the corresponding signals of the NCK/PLC interface:
• Mode groups
• Direction keys of four axes
• WCS/MCS switchover commands
• Overrides
• Key switch
In the basic program (FC 2), FC 27 transmits handwheel selections, modes and other
operation signals from the operator panel or MMC to the NCK/PLC interface in such a way
as to allow the modes to be selected from the machine control panel or the operator panel.
Transmission of MMC signals to the interface can be deactivated by setting the value
"FALSE" in the parameter in FB 1 (DB 7) "MMCToIF".
