11.6.4 System variables
11.6.4.1 Main run variables for motion-synchronous actions
Main run variable_read
The following variables are provided for main run variable_read:
$A_IN[<arith. expression>] digital input (Boolean)
$A_OUT[<arith. expression>] digital output (Boolean)
$A_INA[<arith. expression>] analog input (Boolean)
$A_OUTA[<arith. expression>] analog output (Boolean)
$A_INCO[<arith. expression>] comparator inputs (Boolean)
$AA_IW[<axial expression>] actual position PCS axis (real)
$AA_IB[<axial expression>] actual position BCS axis (real)
$AA_IM[<axial expression>] Actual position MCS axis (IPO setpoints) (real)
With $AA_IM[S1] setpoints for spindles can be
evaluated. Modulo calculation is used for spindles
and rotary axes, depending on machine data
$MA_ROT_IS_MODULO and
$MA_DISPLAY_IS_MODULO.
$AA_OSCILL_BREAK_POS1 Breaking position after external oscillation reversal
when approaching reversal point 1
$AA_OSCILL_BREAK_POS2 Breaking position after external oscillation reversal
when approaching reversal point 2
$AC_TIME Time from the start of the block (real) in seconds
(including the times for the internally generated
intermediate blocks)
$AC_TIMES Time from the start of the block (real) in seconds
(without times for the internally generated
intermediate blocks)
$AC_TIMEC Time from the start of the block (real) in IPO steps
(including steps for the internally generated
intermediate blocks)
$AC_TIMESC Time from the start of the block (real) in IPO steps
(without steps for the internally generated
intermediate blocks)
$AC_DTBB Distance from beginning of block in BCS
(Distance to begin, baseCoor) (real)
