OPERATION

Power On Position Recovery
With the 100S there are two means of position recovery, Position Recall
and Reference Mark Evaluation.

Position Recall

When this feature is active (see setup parameters) the last displayed posi-
tion is stored in memory when power is lost or turned off. When power is
restored, the stored position is recalled and displayed.
Note: Any movement that occurs while power is off will be lost.
Whenever power has been off it is recommended that you re-
establish workpiece datums using the Reference Mark
Evaluation procedure below).

Reference Mark Evaluation

encoders contain internal reference marks, approximately 4"
ENC 125
apart along the length of the encoder. These marks enable you to easily
re-locate your correct position after a power interruption. You relocate
your position, relative to the last established datums, by traversing across
one reference mark on each encoder. You must find a convenient refer-
ence mark on each encoder prior to establishing your datums, and then
use those same marks during the evaluation procedure, after a power
interruption, to re-establish your position relative to your datums.
To perform Reference Mark Evaluation:
• Move near the appropriate reference mark.
• Press and hold the
displays start to flash
• Move slowly past the reference mark until the readout recalls its
position.
• Repeat for each axis.
