Feedback:
Selecting Fagor feedback knowing the name or model of the linear encoder.
Select axis.
Select type of linear encoder, type of signal and type of
reference pulse.
To validate the data for that axis.
Custom feedback selection:
Use this screen to set the characteristics of the encoder.
They are parameters for each axis.
The sections to be set are:
1- Type of axis: Linear or rotary.
1.1- LINEAR: It requests the resolution of the linear
encoder.
1.2- ROTARY: It requests the number of pulses/turn of the encoder and the leadscrew pitch in
mm, inches
or turns per inch.
2- Type of encoder signal: TTL, 1 Vpp or SSI.
2.1- TTL: It requests the resolution of the linear
encoder or Nr of pulses of the encoder.
The following table shows the resolutions
of FAGOR TTL linear encoders.
2.2- 1Vpp: The TTL MULTIPLICATION and
SINUSOIDAL MULTIPLICATION boxes are activated.
* TTL multiplication. Options: 0.5, 1, 2, 4. The factory setting is 4 and it is the one normally used
with FAGOR linear encoders.
* Sinusoidal multiplication. Options: 1, 5, 10, 20, 25, 50. One or the other is used depending on
the resolution to be obtained if the feedback signal is 1Vpp or TTL with distance-coded
reference marks.
Example: We wish to install a FAGOR GP linear encoder (1 Vpp and 20-micron-pitch graduated
glass) with 1 micron resolution:
Therefore, a 1-micron resolution, would require a sinusoidal multiplying factor of 5.
If the feedback signal is TTL with NO distance-coded reference marks, like GX, FT, SY etc. the value
for this parameter will be "1".
