hi last time i did wired motor drive was in 2004, i forgot things. i need look not from drive side -pin but from 7i33 side. 7i33 pin amp P3 (connector) 2 ENCA0 1 3 / ENCA0 2 4 GND 7;1;18; 5 ENCB0 3 6 /ENCB0 4 8 IDX0 5 9 /IDX0 6 11 AOUT0 23 13 ENA0 17 /////////////////////////////////////////////////////////////////////// if new drive has same pin then it can be used. i took this print from documentation, part where talk about useful hardware. i am right? it was 15 years ago, there was part where hardware like servo motor, drive , boards etc had table with corresponding pins. question: does that part of documentation still exist and does new hardware were added ..... ? it can be very helpful . probably new mfg of new hardware need to add /manage that part.
