System variable list
System variable
Description
$AA_FIX_POINT_SELECTED [<Axis>]
Number of fixed point to be approached
$AA_FIX_POINT_ACT [<Axis>] Number of the fixed point on which the axis is currently
located
$P_PROG_EVENT Event-driven program call active
$P_SEARCH_S
Search run: speed, cutting rate
$P_SEARCH_SDIR Block search: programmed direction of spindle rotation in
part program
$P_SEARCH_SGEAR
Search run: Gear stage M code
$P_SEARCH_SPOS
Search run: Spindle position, path
$P_SEARCH_SPOSMODE
Search run: Position approach mode
$AA_ENC_COMP_MIN
EEC table: Starting position
$AA_ENC_COMP_MAX
EEC table: End position
$AA_ENC_COMP
EEC table: Compensation value
$AN_CEC[<t>,<N>] Compensation value for interpolation point <N> of com-
pensation table [<t>]
$AN_CEC_INPUT_AXIS[<t>]
Basic axis
$AN_CEC_OUTPUT_AXIS[<t>]
Compensation axis
$AN_CEC_STEP[<t>]
Interpolation point distance
$AN_CEC_MIN[<t>] Initial position
$AN_CEC_MAX[<t>]
End position
$AN_CEC_DIRECTION[<t>]
Direction-dependent compensation
$AN_CEC_IS_MODULO[<t>]
Compensation with modulo function
$AC_MEA[1]
Query measurement job status signal
$AA_MM[axis] Access to measured value in the machine coordinate
system (MCS)
$AA_MW[axis] Access to measured value in the workpiece coordinate
system
$C_T
Cycle parameter for address T
$P_ISTEST
Program testing status; boolean variable
$P_SEARCH
Program searching status; boolean variable
$P_SEARCHL
Program searching status; real numbers: 1-, 2-, 3-
$P_TOOLNO
Tool number in the spindle turret
$P_TOOLP
Programming tool number
$C_T Programming tool number
$P_TOOLP is inactive when the program code T calls a
tool changing cycle that is defined with MD10717. The tool
number is then represented with "$C_T".
$TC_DP1[Tool number, 1]
Tool type
$TC_DP3[Tool number, 1]
Tool's geometrical parameter: tool length 1
$TC_DP6[Tool number, 1]
Tool's geometrical parameter: tool radius
$TC_DP12[Tool number, 1] Tool wear: the direction of length 1
$TC_DP15[Tool number, 1]
Tool wear: the direction of radius
