40i TS - v1205 - Installation/Operation - (21/29)
2.3- SSI: It is the protocol used to communicate with
absolute encoders. This protocol is configured with the
following parameters:
* Resolution: Only requested if the axis is linear. The
resolution to be used with FAGOR absolute linear
encoders is 0.0001 mm.
*Number of bits: It sets the digital communication
between the encoder and the DRO. The factory setting and the one used with absolute linear
encoders are 32 bits.
Reference
This window sets the parameters related to home search
and the type of reference mark of the encoder. This
configuration must be set for each axis.
* User offset: Offset of the reference point with respect
to the reference zero of the feedback device, independent
for each axis.
Usually, the machine reference zero (reference mark of
the linear encoder) does not coincide with the absolute zero to be used. Therefore, this parameter
must be assigned the value of the distance from the machine zero point to the feedback reference
point.
Factory setting: 0.
This value will be in mm or inches depending on whether the DRO units have been set in "mm" or
"INCH".
* Mandatory Home search. When set to YES, every time
the DRO is turned on, it forces a home search. It is
recommended to set it to YES when the DRO uses
positioning
error
compensation
because
if
the
compensated axis is not homed, the compensation will
not be applied.
* Type: It sets the reference system of the linear encoder:
NONE, NORMAL (INCREMENTAL) or DISTANCE-
CODED.
When selecting DISTANCE-CODED, you must set the
engraving pitch of the linear encoder (20 µm, 40 µm
or 100 µm) and the external multiplying factor (1, 5,
10, 25 or 50).
Exit and save data.

Compensation:
Choose the type of compensation to be used.
1- NONE.
2- LINEAR.
Choose LINEAR from the list, press Enter to validate it.
Press Edit to enter the compensation value. The following window is opened:
Even when working in inches, this value must always be in mm.
Enter the linear compensation value and press Enter.
3- MULTI POINT.
Choose MULTI-POINT from the list and press Enter to validate it.
