In the part program, the variable $P_TOOLFRAME can be used to read and write the
current system frame for TOROT and TOFRAME. The variable returns a zero frame if the
system frame is not configured through MD28082.
In the part program, the variable $P_WPFRAME can be used to read and write the
current system frame for setting workpiece reference points. The variable returns a zero
frame if the system frame is not configured through MD28082.
In the part program, the variable $P_CYCFRAME can be used to read and write the
current system frame for cycles. The variable returns a zero frame if the system frame is
not configured through MD28082.
In the part program, the variable $P_TRAFRAME can be used to read and write the
current system frame for transformations. The variable returns a zero frame if the system
frame is not configured through MD28082.
One can read and write the current system frames for special ISO language commands
in the parts program through the variables. The variable returns a zero frame if the
system frame is not configured through MD28082.
The currently resulting frame that is defined by the ENS-(ACS) coordinate system, can be
read and written through the $P_ACSFRAME variable.
For MD24030 $MC_FRAME_ACS_SET = 0, the frame is calculated as follows:
$P_ACSFRAME =
For MD24030 $MC_FRAME_ACS_SET = 1, the frame is calculated as follows:
$P_ACSFRAME =
$P_PARTFRAME : $P_SETFRAME : $P_EXTFRAME :
$P_ISO1FRAME : $P_ISO2FRAME : $P_ISO3FRAME :
$P_ACTBFRAME : $P_IFRAME :
$P_TOOLFRAME : $P_WPFRAME
$P_PARTFRAME : $P_SETFRAME : $P_EXTFRAME :
$P_ISO1FRAME : $P_ISO2FRAME : $P_ISO3FRAME :
$P_ACTBFRAME : $P_IFRAME :
$P_TOOLFRAME : $P_WPFRAME : $P_TRAFRAME:
$P_PFRAME : $P_ISO4FRAME
