If the feedback device has memory
 Record (save) the value in the encoder memory (refs. E1 and A1 on
FXM motors and E3, A3, E4, A4 on FKM motors) by executing the
RC1 command* ·see note·
The value of the offset generated when replacing the feedback device
is now registered in parameter RP5 (FeedbackRhoCorrection
Parameter) and in the RV3 (FeedbackRhoCorrection) variable of the
drive.
If the feedback device has no memory
 Record (save) the value by executing the GC1 command. References
(ref. I0) with TTL incremental encoder.
Then, turn the disk of the feedback device (not attached to the rotor)
manually (always with the rotor locked), first having removed the
screws that hold the two disks of the feedback device. The angle to
rotate (in mechanical degrees) will be the one given by the formula:
After rotating the disk the calculated angle, tighten the holding screws
in that position. Observe that the disk attached to the shaft cannot be
moved because the rotor has been previously locked.
Execute the GC3 command again in the conditions described for this
procedure and record by executing GC1.
Verify that the value of RP5 is practically zero. If instead of zero, it
registers a value double the rotated angle, it means that it has been
rotated in the opposite direction.
Carry out the whole operation and again and now set the right rotating
direction.
Note.
*
When using a feedback device ref. E1 on the motor and a
CAPMOTOR-2 card at the drive, always follow these steps before
executing the RC1 command:
1. Execute the GC3 command, read the value of RV3 and write it
down.
2. Execute the GV11 command.
3. Now read the RV3 value again and check if it matches the value
you wrote down in step 1. If it is not the same, re-write RV3 with
the value you wrote down.
4. Execute the RC1 command to record in the encoder memory.
Note. Drive variable RV10 is also available, to FAGOR technicians only,
as useful means to adjust the rho when replacing an incremental TTL
encoder. Contact Fagor Automation if you have not been capable of
adjusting the rho following the procedure described earlier.

INFORMATION.
Observe that any feedback device shipped out of the factory already has
the RHO adjusted. Encoders that have memory carry this offset value
stored in it. Therefore, They are all properly adjusted.

Note. When taking a servomotor apart, the feedback device must be
adjusted again following the same procedure described earlier.
