Machine parameters for the axes. Work sets.
I0CODDI2
Pitch between 2 variable distance-coded reference marks.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 0 to 65535.
Default value: 1001.
Associated variable: (V.)[ch].MPA.I0CODDI2[set].xn
The CNC takes this parameter into account if I0TYPE = Distance coded.
The pitch between reference marks is defined in number of waves.
Values to be assigned for Fagor encoders with distance-coded I0.
FOLLOWING ERROR.
Following error is the difference between the theoretical position and the actual (real) position
of the axis. The following error decreases when increasing the axis gain.
The more similar (identical) the following errors of interpolating axes are, the better the
machining of curved sections will be on circular interpolations.
FLWEMONITOR
Type of monitoring of the following error (axis lag).
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: OFF / Standard / Linear.
Default value: Standard.
Associated variable: (V.)[ch].MPA.FLWEMONITOR[set].xn
This parameter determines how the following error will be monitored.
• If set to "OFF", the following error is not monitored, thus no error message will be issued.
Example with a Fagor linear encoder.
