When the axes reach the positioning window, markers M2008 to M2010 are set.
MP1030
Positioning window
Entry range: 0.001 to 2.000 [mm]
MP1030.0 Axis X
MP1030.1 Axis Y
MP1030.2 Axis Z
Encoder monitoring
Monitoring of the encoder signals must be activated with MP31.
If the signal amplitude is faulty the following error messages can appear:
ENCODER <axis> DEFECT If the signal amplitude is no longer being evaluated
AMPL <axis> TOO SMALL If the signal amplitude is too small
OVERLOAD <axis> If the signal amplitude is too large
MP31
Monitoring of the amplitude of the encoder signals
Input values: 0 to 7
Bit 0 Axis X +0 = no monitoring
+1 = monitoring active
Bit 1 Axis Y +0 = no monitoring
+2 = monitoring active
Bit 2 Axis Z +0 = no monitoring
+4 = monitoring active
