Absolute interfaces

Encoders that have a 'C' or a 'Q' in their names use an absolute interface (EnDat or SSI).

There are EnDat encoders with and without incremental A/B sinusoidal signals.
The order designation indicates whether an encoder outputs incremental signals:

EnDat 21

without incremental signals

EnDat 22

without incremental signals

EnDat 01

with incremental signals A/B 1 Vpp

EnDat 02

with incremental signals A/B 1 Vpp

EnDat Hx

with incremental signals HTL (as of 2014)

EnDat Tx

with incremental signals TTL (as of 2014)

x designates: a = 2-fold interpolation

b = without interpolation
c = scanning signals x2
