$AA_VC [31]
Additive axial feedrate override
DOUBLE
Description:
$AA_VC[X]
Additive axial feedrate override for motion-synchronous actions.
The override value must be rewritten in every Ipo cycle or else a value of 0 is applied.
A setting of 0 makes the override inoperative and is not applied to the override value.
The total feedrate cannot be made negative by an override value.
An upper limit is applied to ensure that the maximum axis velocities and acceleration rates cannot be exceeded.
The calculation of other feed components is not affected by $AA_VC.
The override values defined by machine data: $MN_OVR_FACTOR_LIMIT_BIN, $MN_OVR_FACTOR_FEEDRATE[30],
$MN_OVR_FACTOR_AX_SPEED[30] and $MN_OVR_FACTOR_SPIND_SPEED cannot
be exceeded. The additive feedrate override is limited such that the resultant feedrate does not exceed the maximum override
value of the programmed feedrate.
The variable can be accessed only from synchronized actions.

$AA_STAT [31]
Axis status
INT
Description:
The axial variable $AA_STAT[<axis>] determines the axis status. The status "Exact stop fine" is derived from the servo status. See also $AA_IN-
POS_STAT[<axis>]. The following values are possible:
0: No axis status available
1: Traversing movement pending
2: Axis has reached IPO end
3: Axis in position (exact stop coarse)
4: Axis in position (exact stop fine)
Note:
With a position default setting for an axis / spindle, the variable can still indicate the statuses 'Exact stop coarse / fine' during block change
although the axis / spindle is starting to traverse.
Remedy: Also query $AC_TIMEC.

$AA_LEAD_P_TURN [31]
Modulo compensation of the lead value
DOUBLE
Description:
$AA_LEAD_P_TURN[LW]
Current master value positional component
lost as a result of modulo reduction.
The actual master value position
(used internally by the control)
is $AA_LEAD_P[LW] + $AA_LEAD_P_TURN[LW]
If LW is a modulo axis, $AA_LEAD_P_TURN is an
integral multiple of $MA_MODULO_RANGE.
If LW is not a modulo axis, $AA_LEAD_P_TURN is always 0.
Example_1:
$MA_MODULO_RANGE[LW]=360
$AA_LEAD_P[LW]
=290
$AA_LEAD_P_TURN[LW] =720
The actual master value position
(used internally by the control) is 1010.
Example_2:
$MA_MODULO_RANGE[LW]=360
$AA_LEAD_P[LW]
=290
$AA_LEAD_P_TURN[LW] =-360
The actual master value position
(used internally by the control) is -70.

$AC_RPVALID [31]
Repos position valid
BOOL
Description:
$AC_RPVALID[X]
$AC_RPVALID[axis identifier] returns TRUE if a valid Repos position, which can be interrogated with $AC_RETPOINT[axis identifier], is available
for this axis.
Valid Repos positions are generally available while system and user ASUBs are being processed. However, this is not the case in the following
situations:
- The ASUB activates a modified radius when tool radius compensation is active. $AC_RPVALID then returns FALSE for geometry axes while the
ASUB is running. The newly calculated Repos positions only become available with the approach blocks generated by the REPOS command.
- The end position of the axis was last specified by the main run (FC18, synchronized actions, reciprocation, transfer from another channel after
axis replacement).

$AA_DTSB [31]
Distance from start of motion in BCS
DOUBLE
Description:
Axial variable $AA_DTSB[ax] determines the axial distance (with algebraic sign) from the start of motion in the basic coordinate system for
positioning and synchronized axes. The programmed position is the only factor used to calculate the distance. If the axis is a coupled axis, the
position component derived from the axis coupling is not considered.

$AA_COUP_CORR [31]
Generic coupling: Compensation value for 'Correct syn-
DOUBLE
chronism difference'
Description:
The variable $AA_COUP_CORR[Sn] with spindle Sn (n: spindle number), example S2: spindle 2 or C: axis C
serves to execute the "Correct synchronism error" functionality, and provides the compensation value for the position offset for generic
couplings with CPFRS="MCS" (or CPSETTYPE="COUP").
For the duration (MD 30455 MISC_FUNCTION_MASK, bit 7) of the activation of the NC/PLC interface signal <Synchronlauf_nachfuehren/>
(Correct synchronism error) for the following spindle in active coupling, the actual values of this spindle are compared with the setpoint values.
The difference is the compensation value that can be read with the system variables $AA_COUP_CORR.
If the compensation value is known, this value can also be written directly into the system variable. The NC/PLC interface signal <Synchron-
lauf_nachfuehren/> (Correct synchronism error) should not be set in this case. The variable becomes effective only if a CP coupling has been
activated for the spindle with CPSETTYPE="COUP" or CPFRS="MCS". If the axis is not a configured spindle, the writing is ignored.
In the coupling module, the variable $AA_COUP_CORR is considered, and it corrects the setpoint values.
The compensation value is automatically deleted for reference point approach and zero mark synchronization of spindles. The system variable
then returns the value 'zero'.
Depending on the application, the compensation value can also be deleted at an earlier point in time by writing the value '0' to the variables.

$AA_INPOS_STAT [31]
State of the programmed position
INT
Description:
The variable $AA_INPOS_STAT[<axis>] returns the status of a programmed axis position. The indexing position is used for indexing axes. In the
case of spindles, $AA_INPOS_STAT refers to the spindle position of SPOS/SPOSA/M19. In speed control mode M3/M4/M5/SPCOF and after M70
value 0 is always read.
$AA_INPOS_STAT always refers to the programmed position. The programmed position cannot be reached if end positions change during
interpolation (delete distance-to-go, NC Stop, REPOS). At zero speed, the variable then gives the value 0.
Axis positions can be programmed through the part program, synchonized actions, FC18 or as indexing positions.
The variable returns the following values:
0: No status available (axis / spindle outside the programmed position)
1: Awaiting traversing movement
2: Position reached via setpoint
3: Position reached via 'Exact stop coarse'
4: Position reached via 'Exact stop fine'
Note 1: The status referring to the programmed position is independent of the operating mode (AUTOMATIC, JOG, MDI, ...)
Note 2: If additional position components (e.g. following axis couplings, corrections, compensations etc.) are inserted, then the programmed
position is no longer identical with the machine axis position. During the period of additional traversings, exact stop signals are deleted, and
the status can fall to the value 1.
Note 3: When approaching a position with tight exact stop limits, overshooting can cause the status to drop briefly again in relation to the
dynamics of an axis / spindle.
Note 4: Function-dependent, the signals 'Spindle in position' and 'Indexing axis in position' are output on the axial VDI interface.
Note 5: When determining the status of a path axis with G643/G644/G645, the variable $AA_INPOS_STAT can remain at the value '1' on account
of smoothing behavior during the path motion. Remedy: Use variable $AA_STAT (however the variable $AA_STAT does not check whether a
programmed position has been reached).

$AA_DEPAXO [31]
Dependence on other axes
INT
Description:
The variable $AA_DEPAXO[AX] returns an axis code for the stated axis AX, which contains all machine axes with a mechanical dependence on
the stated axis.
A dependency is produced by:
Active coupling modules, the following axis is dependent on the leading axis
Active transformations, output axes of the transformation are dependent
on the input axes of the transformation
Closed gantry groupings, the slave axes are dependent
on the master axis
The given axis itself is also returned in the axis code
The axis code indicates how the machine data $MC_AXCONF_MACHAX_USED refers not directly to the machine axes but to the logical NCK
machine axis image ($MN_AXCONF_LOGIC_MACHAX_TAB).
Bit 0 = 0 There is no dependence on the logical machine axis AX1
Bit 0 = 1 There is a dependence on the logical machine axis AX1
Bit 1 = 0 There is no dependence on the logical machine axis AX2
Bit 1 = 1 There is a dependence on the logical machine axis AX2
and so on.

INT
Description:
$AA_FIX_POINT_SELECTED[<Axis>]
0: No fixed point selected
> 0: Number of the selected fixed point
Via the NC/PLC interface signal <Aktiviere_Festpunktfahren_inJOG/> (Activate fixed point approach in JOG) you can activate the fixed point
approach in the operating mode JOG.
Bits 0-2 indicate the number of the fixed point to be approached.
Activation is confirmed via the NC/PLC interface signal <Festpunktfahren_in_JOG_aktiv/> (Fixed point approach in JOG active). The bits indicate
the number of the fixed point being approached.

$AA_BRAKE_CONDB [31]
Context-sensitive conditions for interpolator stop in the
INT
BCS
Description:
The axial variable $AA_BRAKE_CONDB[ax] indicates the braking requests (conditions) pending on the axis / spindle to the interpolator stop. A
braking request consists of a collision direction referring to a coordinate axis in the BCS, and a braking priority referring to the machining level.
If the axis / spindle receives a new braking request due to these conditions, bit 0 is set in $AA_BRAKE_STATE[X] (in the next IPO cycle).
Bits 0 to 3 show the highest braking priority in positive direction:
0x0: No pending braking request
0x1: Priority 1 includes all positioning actions (G0, POS, SPOS)
0x2: Priority 2 includes DYNNORM and all movements of priority 1
0x3: Priority 3 includes DYNPOS and all movements of priorities 1 to 2
0x4: Priority 4 includes DYNROUGH and all movements of priorities 1 to 3
0x5: Priority 5 includes DYNSEMIFIN and all movements of priorities 1 to 4
0x6: Priority 6 includes all movements (incl. DYNFINISH). The request can also be triggered by a CP SW Limit Stop.
0x7: Priority 7 includes all movements. The request was triggered by the NC/PLC interface signal <VorschubHalt-SpindelHalt/> (Feed stop /
spindle stop). Brakes are always applied independently of the movement direction.
0xD: Priority 13 includes all movements. Axial braking is executed using the Emergency Stop braking ramp.
In bits 16 to 19 the highest braking priority is shown in negative direction:
0x0 to 0xD: Same significance as with bits 0 to 3
All other bits are reserved and not set.
When displaying the value of the variables in hexadecimal format, the fifth digit from the right indicates the braking priority in negative
direction and the digit on the right the braking priority in positive direction.
