Description:
MD34110 $MA_REFP_CYCLE_NR = 0 -----> axis-specific referencing
Axis-specific referencing is started separately for each machine axis with
the NC/PLC interface signal DB380x DBX4.7 / 4.6 (Plus/minus travel keys).
Up to 8 axes (840D) can be referenced simultaneously.
The following alternatives are provided for referencing the machine axes in a
specific sequence:
• The operator has to observe the correct sequence on startup.
• The PLC checks the sequence on startup or defines the sequence itself.
• The channel-specific referencing function is used.
MD34110 $MA_REFP_CYCLE_NR = 1 -----> channel-specific referencing
Channel-specific referencing is started with the NC/PLC interface signal
DB3200 DBX1.0 (Activate referencing). The control acknowledges a successful
start with the NC/PLC interface signal DB3300 DBX1.0 (Referencing active).
Each machine axis assigned to the channel can be referenced with channel-spe-
cific referencing (this is achieved internally on the control by simulating
the plus/minus traversing keys). The axis-specific MD34110 $MA_REFP_CYCLE_NR
can be used to define the sequence in which the machine axes are referenced:
-1 means:
The machine axis is not started by channel-specific referencing, and NC start
is possible without referencing this axis.
0 means:
The machine axis is not started by channel-specific referencing, and NC start
is not possible without referencing this axis.
1 means:
The machine axis is started by channel-specific referencing.
2 means:
The machine axis is started by channel-specific referencing if all machine
axes identified by a 1 in MD34110 $MA_REFP_CYCLE_NR are referenced.
3 means:
The machine axis is started by channel-specific referencing if all machine
axes identified by a 2 in MD34110 $MA_REFP_CYCLE_NR are referenced.
4 to 8 :
As above for further machine axes.
Setting the channel-specific MD20700 $MC_REF_NC_START_LOCK (NC start disable
without reference point) to zero has the effect of entering -1 for all the
axes of a channel.
