Variables
Descriptions
$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
$TC_DP24[Tool number, 1] Tool's dimension:
0: normal
1: oversize
$TC_DP25[Tool number, 1]
