lagPeak Peak of current following error. The maximum peak of 
the following error is determined and displayed here.

targetPos Absolute target position of the axis
totalDistance Total travel of the axis
motorTemperature Motor temperature in degrees Celsius
utilization Utilization of axis in %
rpfOffset Coordinate system offset between switch-on position 
and reference point
spindleTurns. Spindle revolutions – the value of the active spindle is 
calculated.
ModCounter Only available for modulo axes. The counter is updated 
with each zero crossover of the current nominal 
position value of a modulo axis. All positions leaving the 
IPO (display, PLC, etc.) are calculated from the current 
position (0 to 359.9999 degrees) + moduloCounter * 
360. The counter can be set, cleared, stopped and 
restarted from the geometry module. The modulo 
counter is saved cyclically in SRAM and restored during 
control startup. 
ModCounterAct Only available for modulo axes. The counter is updated 
with each zero crossover of the current actual position 
value of a modulo axis. All positions leaving the IPO 
(display, PLC, etc.) are calculated from the current 
position (0 to 359.9999 degrees) + moduloCounter * 
360. The counter can be set, cleared, stopped and 
restarted from the geometry module.
absNomPosOfFilt1 Absolute nominal position before the nominal position 
value filter (see configuration data System/CfgFilter)
absNomPosOfFilt2 Absolute nominal position before the nominal position 
value filter (see configuration data System/CfgFilter)
absNomPosBase Nominal position without compensation of virtual axes
lastIpoPos Last interpolated nominal value of interpolator
syncPosDiff Position difference during spindle synchronism (for 
slave spindle)
absTouchPos Absolute actual position provided by measuring system
virtStartPos Starting position of virtual axis (reference position). 
Basis for determining the relative virtual offset.
requestedPos Position commanded by HMI for returning to the 
contour
absProgFeed Currently programmed speed
