ENCODER 1 (PRIMARY FEEDBACK)
ENDAT ABSOLUTE ENCODER
The EnDat interface is a Heidenhain
interface that is similar to SSI in the use
of clock and data signals, but which also
supports analog Sin/Cos channels from
the same encoder. The number of position
data bits is programmable as is the use
of Sin/Cos channels. Use of Sin/Cos
incremental signals is optional in the EnDat
specification.

ABSOLUTE-A ENCODER
The Absolute A interface is a serial, half-duplex type that is electrically the same as RS-485.
Note the battery which must be connected. Without it, the encoder will produce a fault condition.
