2.12.22 FC 19: MCP_IFM transmission of MCP 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
Axis selections
WCS/MCS switchover commands
Traversing keys
Overrides
Key-operated switch
In the basic program (FC 2) handwheel selections, modes and other operating signals are
transferred from the operator panel front (HMI) to the NCK/PLC interface so that the modes
support selection from the MCP or HMI.
Transfer of MMC 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 to the NC channel in addition to the "Rapid
traverse override" (DBB 5) interface byte if the "Feed override for rapid traverse
effective" HMI signal is set (exception: Switch setting "Zero"). "Rapid traverse override
effective" is also set with this HMI 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 of the HMI are decoded and activated in the associated
machine-axis interface or geo axis interface of the relevant handwheel (only if FB 1
parameter "HWheelMMC : = TRUE").
The LEDs on the machine control panel derived from the selections in the acknowledgment.
Feedrate and spindle Start/Stop are not transferred to the interface, but output modally as a
"FeedHold" or "SpindleHold" signal. The user can link these signals to other signals leading
to a feed or spindle stop (this can be implemented, e.g., using the appropriate input signals
in FC 10: AL_MSG). The associated LEDs are activated at the same time.
If the machine control panel fails, the signals it outputs are preset to zero; this also applies to
"FeedHold" and "SpindleHold" output signals.
