8.2.2.1 Status bit "HomPosAvailable"
Bit 13 ("HomPosAvailable") in the MCK status word 1 shows that the reference position has been
detected and is known in the drive.
An available reference information (bit 13 = "1") and thus a valid measuring system is required for
the following functions:
• Positioning in the "Positioning
" operating mode in the following (C01300/1...15) positioning
modes:
• 1: absolute (beeline)
• 4: absolute (Cw)
• 5: absolute (Ccw)
• 8: absolute (shortest path) to TP
• 11: absolute (Cw) to TP
• 12: absolute (Ccw) to TP
• Response to set software limit positions
• Stopping on breakpoints in the "Manual jog
" operating mode
• Traversing of a sequence profile with absolute measuring reference in the "Homing
" mode after
homing is completed
Resetting the reference information
The following events reset bit 13 ("HomPosAvailable") in the MCK status word 1:
• Setting bit 10 ("HomResetPos") in the MCK control word 1
• Overtravelling the 32-bit position display area at the limit ±2147483647 increments when the
cycle (C1201/1
) = "0 units".
• Change of the position encoder selection in C00490
• Change of the cycle in C1201/1
• Writing on the machine parameters if bit 1 ("delete reference when machine data is changed")
is set in C2652
.
• Machine parameters are cycle (C1201/1
), gearbox factors (C1202/1...2, C1203/1...2) and feed
constant (C1204
).
• The mere writing of these parameters (even when the previous value is used) causes the
reference to be deleted!
• Encoder error when a position encoder is used at the multi-encoder interface
• Resolver error when a resolver is used as position encoder
• Mains recovery at a cycle set unlike "0 units" in C1201/1
and if the position difference at
reference recovery is higher than 1000 cycles.
