II - 3<br />
Encoders and Measured Value Display<br />
This chapter describes all operating parameters which you must set<br />
for the encoders and measured value display. Most entries can be<br />
found in the operating instructions for your encoder.<br />
Chapter II - 2 contains a list of operating parameters in which you<br />
can record your entries.<br />
• Adapting the encoder<br />
- Encoder output signals 16 µA or 40 µA<br />
- Reference marks on the encoder:<br />
distance-coded or one reference mark<br />
- Deactivation of reference mark evaluation<br />
- Definition of the coordinate axes<br />
- Counting direction of the encoder signals<br />
- Encoder monitoring<br />
- Linear axis-error compensation<br />
• Selection of display step<br />
• Setting the measured-value display<br />
- Designations of the coordinate axes<br />
- Unit of measurement<br />
- Display of rotary axes<br />
- Angle display<br />
- Axis combination<br />
- Radius/diameter display<br />
Adapting the encoders<br />
Encoder output signal: P81.*<br />
Encoder with 16 µA output signal: P81.* = 0<br />
Encoder with 40 µA output signal: P81.* = 1<br />
The position feedback encoders on the machine may have one<br />
reference mark or several distance-coded reference marks.<br />
Reference marks on the encoder: P43.*<br />
One reference mark (none): P43.* = 0<br />
Distance-coded reference marks (500 • TP): P43.* = 500<br />
Distance-coded reference marks (1000 • TP): P43.* = 1000<br />
Distance-coded reference marks (2000 • TP): P43.* = 2000<br />
Distance-coded reference marks (5000 • TP): P43.* = 5000<br />
Reference mark evaluation can be deactivated separately for<br />
each axis. Note that the datum points for those axes are then<br />
no longer stored in non-volatile memory.<br />
Reference mark evaluation: P44.*<br />
Evaluate reference marks (yes): P44.* = 0<br />
Do not evaluate reference marks (no): P44.* = 1<br />
