Incremental
In the Motor Encoder lines or Position Encoder lines field, enter the number of encoder
lines (see encoder or motor data sheet). As indicated by the counts field, the number of
encoder counts per revolution is equal to 4 x the number of lines. Enable Encoder Loss
Detection and/or Index Loss detection if desired.

A Format
In the Bits text field, enter the number of bits (see encoder data sheet). In the counts per
rev text field enter the counts per revolution (see encoder data sheet). Check Ignore
Battery Error when needed.
!
WARNING
When a battery error exists, absolute position may not be true (whether
the Ignore Battery Error option has been checked or not).
FAILURE TO HEED THIS WARNING CAN CAUSE EQUIPMENT
DAMAGE, INJURY, OR DEATH.
Analog
In Fundamental Lines, enter the number of fundamental encoder lines (see encoder or
motor data sheet). As indicated by the Fundamental Counts field, the number of
fundamental encoder counts per revolution is equal to 4 x the number of Fundamental
Lines.
Optionally modify the encoder resolution by changing the Interpolation value. The
interpolated resolution (Interpolated Counts Per Rev) is the product of Fundamental
Counts value and the Interpolation value.
