Modulo rotary axis/spindle: programmed positions must be in the modulo range.
Otherwise an alarm is output.
Bit 0 = 1:
When programming positions outside the modulo range, an alarm is not signaled. The
position is modulo-converted internally.
Example: B-5 has the same significance as B355, POS[A]=730 is identical to POS[A]=10
and SPOS=-360 behaves the same as SPOS=0 (modulo range 360 degrees)
Bit 1 = 0:
Determination of reference point position of rotary, distance-coded encoders analog
(1:1) in relation to the mechanical absolute position.
Bit 1 = 1:
Determination of reference point position of rotary, distance-coded encoders within
the configured modulo range.
For rotary axes with MD30310 $MA_ROT_IS_MODULO=0, which use rotary, distance-coded
encoder MD34200 $MA_ENC_REFP_MODE=3, the reference point position is determined in
response to MD30330 $MA_MODULO_RANGE and MD30340 $MA_MODULO_RANGE_START. This is
automatically adapted to the traversing limits of the modulo range. For rotary axes
with
MD30310 $MA_ROT_IS_MODULO=1,
this bit has no significance, as the reference point
position is always determined within the modulo range.
Bit 2 = 0:
Modulo rotary axis positioned at G90 with AC as default.
Bit 2 = 1:
Modulo rotary axis positioned at G90 with DC as default (shortest path).
Bit 3 = 0:
For spindle/axis disable $VA_IM, $VA_IM1, $VA_IM2 supply the setpoint value.
Bit 3 = 1:
For spindle/axis disable $VA_IM, $VA_IM1, $VA_IM2 supply the actual value.
Bit 4 = 0:
Synchronous spindle coupling, slave spindle: cancellation of feedrate enable will
brake the coupled group.
Bit 4 = 1:
Slave spindle: Feedrate enable only applies to the interpolation portion of the
overlaid motion (SPOS, etc.) and has no impact on the coupling.
Bit 5 = 0:
Synchronous spindle coupling, slave spindle: Position control, feedforward control,
and parameter block are set in response to the master spindle.
Bit 5 = 1:
Synchronous spindle coupling: The parameters of the slave spindle are set as they
would be without coupling.
Bit 6 = 0:
Programming of FA, OVRA, ACC, and VELOLIM is applied separately to spindle and axis
modes. The assignment is made by the programmed axis or spindle identifier.
Bit 6 = 1:
Programming of FA, OVRA, ACC, and VELOLIM is applied jointly to spindle and axis modes,
irrespective of the programmed identifier.
Bit 7 = 0:
Synchronous spindle, correct synchronism error: Correction value $AA_COUP_CORR[Sn] is
continuously calculated as long as the NC/PLC interface signal DB380x DBX5007.6
(Correct synchronism) is set and setpoint-related synchronism is present.
Bit 7 = 1:
Synchronous spindle, correct synchronism error: Correction value $AA_COUP_CORR[Sn] is
calculated only at the moment the NC/PLC interface signal DB380x DBX5007.6 (Correct
synchronism) is set from 0 to 1.
