The values are expressed in the internal measurement unit: mm/10, mm/100, μm, μm/10 or μm/100 for linear axes
(see 4.8) and deg/10000 for rotary axes.
The absolute value contained in a word gives the maximum backlash on the corresponding axis. The sign determines
the direction of backlash correction.
Value > 0: Positive correction applied when the axis moves in the positive direction.
Value < 0: Negative correction applied when the axis moves in the positive direction.
UNI-TE request (see UNI-TE Protocol User’s Manual)
The backlash error compensation can be modified by a UNI-TE request. A reset (CNC reset) resets the CNC to the
state specified by P18.
