3.14 Incremental 1 Vpp interface with commutation for synchronous and linear drives
in feed-through mode (listening-in)
3.14.1 Adapter for monitoring (listening-in) between TNC and incremental rotary encoder in synchronous
motors (e. g. ERN 1387 with AB track and CD commutation track)
Figure A Measured at the control input (25-pin speed encoder input):
Note
In the adapter ID 1075630-01 the temperature wires lead from input IN to output OUT
(PIN 5 IN / PIN 5 OUT and PIN 6 IN / PIN 6 OUT).
