10.5 Frames
The following current system frames exist:
• $P_SETFRAME
In the part program, the variable $P_SETFRAME can be used to read and write the current system frame for
PRESET and scratching. The variable returns a zero frame if the system frame is not configured through
MD28082.
• $P_EXTFRAME
In the part program, the variable $P_EXTFRAME can be used to read and write the current system frame for
the zero offset external. The variable returns a zero frame if the system frame is not configured through
MD28082.
• $P_PARTFRAME
In the part program, the variable $P_PARTFRAME can be used to read and write the current system frame for
TCARR and PAROT for toolholders with orientation capability. The variable returns a zero frame if the system
frame is not configured through MD28082.
• $P_TOOLFRAME
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.
• $P_WPFRAME
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.
• $P_CYCFRAME
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.
• $P_TRAFRAME
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.
• $P_ISO1FRAME, $P_ISO2FRAME, $P_ISO3FRAME, $P_ISO4FRAME
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.
• $P_RELFRAME
In the part program, the variable $P_RELFRAME can be used to read and write the current system frame for
relative coordinate systems. The variable returns a zero frame if the system frame is not configured through
MD28082.
