$AC_TRAFO_PARSET
Transformation data set number
INT
Description:
$AC_TRAFO_PARSET
The variable contains the value 0 if no kinematic transformation is active.
If a conventionally defined transformation (i.e. not using kinematic chains) is active, the variable contains the number of the current trans-
formation data set.
Note the special meaning with a parameterized persistent transformation
(Bit 1 of $MC_TRAFO_MODE_MASK is set to 1):
With TRACON, the number of the data set of the first chained transformation
is returned.
If only the persistent transformation is active, 0 is returned.
If a transformation defined with kinematic chains is active, the variable contains the number of the $NT data set with an offset of 1000; this
means that the first transformation returns the value 1001.

Variable $AC_FIFO1[n] is a stack with first in first out characteristics. This stack memory can be used for cyclic measuring operations.
$MC_NUM_AC_FIFO is used to define the number of FIFO variables $AC_FIFO1 - $AC_FIFO10.
The elements of the stack memory are saved in R variables. The length of all FIFO variables is configured with $MC_LEN_AC_FIFO.
$MC_START_AC_FIFO is used to specify the number of the start R variable, from which the FIFO elements are stored.
R variables assigned to FIFO areas should not be written elsewhere.
The number of R variables must be set in machine data $MC_MM_NUM_R_PARAM such that all FIFO variables can be accommodated:

$A_DLB [n]
Link variable byte
INT
Description:
Variable $A_DLB[n] enables reading and writing of a data byte (8 bits) which can be transmitted to other channels or NCUs across the NCU link.
$MC_MM_NUM_LINKVAR_ELEMENTS is used to define the number of elements available to the user for programming link variables ($A_DLx).
The negative value range of this variable applies to write operations only. The variable can thus store negative values. Only the corresponding
positive value can be read back.
Index 1:
The dimension is configured via $MC_MM_SIZEOF_LINKVAR_DATA.

DOUBLE
Description:
$AC_TIMES
Time from block start (REAL) in seconds (excluding times for internally generated intermediate blocks).
Each programmed block can be divided into a sequence of sub-blocks for sequential processing.
$AC_TIMES is set to zero o_n_l_y during the 1st cycle of the 1st block in the sequence. It is then incremented in seconds. The variable therefore
allows time measurements to be taken over the whole block sequence.
The variable can be accessed only from synchronized actions.

$AC_TIMER [1]
User timer
DOUBLE
Description:
Array variable $AC_TIMER[n] is an application-related timer. The time in seconds is counted in multiples of an interpolation cycle.
The timer is started by assigning a value:
$AC_TIMER[n]=<start value>
The timers can be stopped by assigning a negative value:
$AC_TIMER[n]=-1
The current timer count can be read while the time variable is running or stopped. When the time variable is stopped by assigning -1, the last
count value remains stored in the variable and can continue to be read.
Index 1:
The dimension is defined via $MC_MM_NUM_AC_TIMER.

$AC_OVR
Path override can be specified via synchronized action
DOUBLE
Description:
The variable $AC_OVR determines the path override specifiable via synchronized action. The path override must be set by assigning a value
cyclically to $AC_OVR in each interpolation cycle. Otherwise $AC_OVR is reset to 100%.
The total path override can be read via $AC_TOTAL_OVR.
The total path override without the programmable override (e.g. OVR = 10) is limited to the maximum value defined by the machine data
$MN_OVR_FACTOR_LIMIT_BIN or $MN_OVR_FACTOR_FEEDRATE[30]. Values less than 0 are not allowed.

$AC_PLC_OVR
PLC override
DOUBLE
Description:
The variable $AC_PLC_OVR determines the path override defined by the PLC. This is the feedrate override that is set via the Machine Control
Panel.
The rapid traverse override (settable on the Machine Control Panel) is effective with G0 blocks. If the rapid traverse reduction has been activated
via the operator interface, then, with G0 blocks, $SC_OVR_RAPID_FACTOR is also taken into account multiplicatively.

$AC_TOTAL_OVR
Overall path override
DOUBLE
Description:
The variable $AC_TOTAL_OVR supplies the total path override. The value is calculated from the override from the PLC, the synchronized action
override ($AC_OVR) and the programmable override (e.g. OVR = 10).
$AC_TOTAL_OVR = $AC_PLC_OVR * $AC_OVR * OVR /10000.

$AC_VC
Additive path feed override
DOUBLE
Description:
$AC_VC
Additive path feed override for synchronized actions
The override value must be rewritten in every Ipo cycle or else a value of 0 is applied.
The override value is ignored with an override of 0. Otherwise, the override value is applied independently of the override.
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 maximum feedrate is
limited by $MN_OVR_FACTOR_LIMIT_BIN, $MN_OVR_FACTOR_FEEDRATE[0-30] and $MN_PERMANENT_FEED[0-3] (see machine data).
The override value is not included in the calculation in the case of G0, G33, G331, G332 and G63.
The variable can be accessed only from synchronized actions.

$AC_REQUIRED_PARTS
Definition of the number of required workpieces
DOUBLE
Description:
$AC_REQUIRED_PARTS can be used to define the number of workpieces
which, when reached, causes the number of actual workpieces $AC_ACTUAL_PARTS
to be reset (workpiece target).
Channel MD 27880 $MC_PART_COUNTER can be used to activate the
display alarm "workpiece target reached" and channel VDI signal "workpiece target reached":
Bit 0 = 1: $AC_REQUIRED_PARTS counter is active
Further meaning of bit 1 only when bit 0 = 1:
Bit 1 = 0: Alarm/VDI output when $AC_ACTUAL_PARTS matches $AC_REQUIRED_PARTS
Bit 1 = 1: Alarm/VDI output when $AC_SPECIAL_PARTS matches $AC_REQUIRED_PARTS
Use in NC program:
$AC_REQUIRED_PARTS = ACTUAL_LOS

Bit 4 = 1: $AC_TOTAL_PARTS counter is active
Further meaning of bits 5-6 only when bit 4 = 1:
Bit 5 = 0: The $AC_TOTAL_PARTS counter is incremented by 1 on a VDI output of M02/M30
Bit 5 = 1: The $AC_TOTAL_PARTS counter is incremented by 1 when the M command from MD PART_COUNTER_MCODE[0] is output.
Bit 6 = 0: $AC_TOTAL_PARTS active even during program test/block search
Bit 6 = 1: No processing of $AC_TOTAL_PARTS during program test/block search
Use in NC program:
IF $AC_TOTAL_PARTS> SERVICE_COUNT GOTOF MARK_END

$AC_ACTUAL_PARTS
Number of workpieces currently machined
DOUBLE
Description:
The $AC_ACTUAL_PARTS counter records the number of all workpieces machined since the start time.
When the workpiece target is reached ($AC_REQUIRED_PARTS), the counter is automatically reset ($AC_REQUIRED_PARTS not equal to 0).
The counter is incremented by 1 when the MC command defined in channel MD 27882$MC_PART_COUNTER_MCODE[1] is output to the PLC.
The counter is automatically reset only when the control boots with default values.
Channel MD 27880 $MC_PART_COUNTER can be used to activate the timer:
Bit 4 = 1: $AC_TOTAL_PARTS counter is active
Further meaning of bits 5-6 only when bit 4 = 1:
