Wiring 30A8 Drive to 7I77 Daughtercard was created by wilderben
I'm wiring a CNC mill with the components on the attached diagram below:
I'm having trouble matching the wires coming out of the 30A8 Drive to the 7I77 Daughtercard.
(See the diagram below)
Can anyone help me?

basic drive connections are:
TB5 GND to REF-
TB5 ANALOG OUT to REF+
TB5 ENABLE+ to INHIBIT
TB5 ENABLE- to GND
The analog input connections assume that the drives signal ground is common with the 7I77 ground.
You will need to set the drive for 'pull-to-ground for enable'
From AMC manual:
Inhibit Input Check inhibit input for correct polarity (that is, pull‐to‐ground to inhibit or pull‐to‐ground to enable). Inhibit configuration depends either on the DIP switch settings or a 0 ohm SMT resistor marked on the board. Also, keep in mind that noise on the inhibit line could be a cause for a false inhibit signal being given to the drive.
With no tachometer you will need to set your drive for torque mode
(There is another possibility which is to use a spare 7I77 analog output to simulate the tachometer and run the drive in velocity mode, but this is more involved)
