7.9.2 Absolute Encoder with Sin/Cos signals
Single-turn or Multi-turn analog (Sin/Cos) absolute encoder with a serial
interface (EnDat 2.1/2.2, Biss-B, Biss-C) . This encoder type is operated as
an analog Sin/Cos encoder. The absolute position (and some additional in-
formation) is read during initialization using the digital serial interface.
NOTICE
RS422 index channel is not available in this configuration.
TTL index is available through EncInX.
