2.4.11 Positions in the coordinate system
The setpoint positions in the coordinate system can be read via the following system
variables. The actual values can be displayed in the WCS, SZS, BZS or MCS via the PLC.
There is a softkey for actual-value display in MCS/WCS. Machine manufacturers can define
on the PLC side, which coordinate system corresponds to the workpiece coordinate system
on their machines. The HMI requests the appropriate actual values from the NCK.
$AA_IM[axis]
The setpoints in the machine coordinate system can be read for each axis using the
variables $AA_IM[axis].
$AA_IEN[axis]
The setpoints in the settable zero system (SZS) can be read for each axis using the
variables $AA_IEN[axis].
$AA_IBN[axis]
The setpoints in the basic zero system (BZS) can be read using the variable $AA_IBN[axis].
$AA_IW[axis]
The setpoints in the workpiece coordinate system (WCS) can be read using the variable
$AA_IW[axis].
