FC 19: MCP_IFM transmission of MCP signals to interface
Description of Functions
With FC MCP_IFM (M variants), the following are transferred from the machine control panel
(MCP) to the corresponding signals of the NCK/PLC interface:
•
Mode groups
•
Axis selections
•
WCS/MCS switchover commands
•
Traversing keys
•
Overrides
•
Key switch
In the basic program (FC 2), the handwheel selections, modes and other operation signals
are transmitted 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.
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).
The following specifications apply to the feed override, axis travel keys and INC keys
depending on the active mode or on the coordinate system selected:
•
Feed override
:
–
The feed override is transferred to the interface of the selected channel and to the
interface of the axes.
–
The feed override signals are transferred in addition to interface byte "Rapid traverse"
override (DBB 5) to the NC channel if MMC signal "Feed override for rapid traverse
effective" is set (exception: Switch setting "Zero"). "Rapid traverse override effective"
is also set with this MMC signal.
•
Machine functions for INC and axis travel keys:
–
When the MCS is selected, the signals are transferred to the interface of the selected
machine axis.
–
When the WCS is selected, the signals are transferred to the geoaxis interface of the
parameterized channel.
–
When the system is switched between MCS and WCS, the active axes are generally
deselected.
The handwheel selection signals from the MMC are decoded and activated in the
machine-axis or the Geo-axis interface of the handwheel selected (only if parameter
"HWheelMMC := TRUE" in FB 1).
The LEDs on the machine control panel derived from the selections in the acknowledgment.
