Power-On Position Recovery
Position-Trac
Certain ACU-RITE encoders, such as the ENC 150, contain closely-spaced reference marks that enable the display to show the correct position after a power interruption. The readout will indicate when power has been lost, and will prompt you to move each axis until a reference mark is located. By traversing the reference marks once in each axis, you will re-establish the display position relative to the last known zero. The most you will ever have to move an axis is about one inch. You must move in a positive count direction. A flashing decimal point will indicate that the last position has not been recalled.
If you use an encoder that does not have the Position-Trac feature, the procedure for recovering your position is slightly different. Reference marks on these encoders are about 8” apart. You must find a convenient reference mark and then use the same mark every time.
1.Move near the desired reference mark.
2. Press and hold the INCRABS key until the decimal point starts to flash.
3.Move slowly past the reference mark until the readout recalls its position. You must move in a positive direction.
