6 Technical data
Digital incremental encoders
Digital incremental encoders with RS422-compatible A/B/N signals with a line count of up
to 16,384 lines can be connected (e.g. ERN 420). In addition, Hall generator signals with a
TTL level for determining the commutation position can also be connected.
