Actual value of the axis feed rate [mm/min].
Calculated from position encoder
Nominal value of the axis feed rate [mm/min]. Axis
feed rate calculated from the difference from the
nominal position values. The following error isn't
included.
Contouring feed rate [mm/min]
Actual position [mm]
Nominal position [mm]
Following error of the position controller [µm]
Signal 1 of the position encoder
Signal 2 of the position encoder
The signal last recorded is saved.
The PLC operands (B, W, D, I, O, T, C) are recorded.
Enter the operands in the input field next to the PLC.
