Controller hardware suggestions for first DIY build

I would probably get Longs Motor DM542A drives

I just ordered 4ea of these to use with my 7I76E card. DM542A

I will use my G540 with something else, I need to get my table running with LinuxCNC soon in order to begin working with the pneumatic actuators. Do you have any wiring diagrams for this stepper and the 7I76E?

Its very easy. Just connect the 4 step and direction wires. and the 48v power and shielded wires to the motor. Connect the shield to the cabinet frame ground and leave shield at the motor end unconnected.

DO NOT attach any wires to the DM542 enable connector.

Are you describing the wires between the DM542A and the motor?

Which wires run between the DM542A and 7I76E and which wires run between the motor and the DM542A?

48v to DM542A . Connect the motor to the driver using a seperate shielded cable to each motor and the shield connected as I mentioned. Size the wires to carry the current given the length.

Then its just a matter of connecting +step & -step and +dir & -dir on the 7i76e to the DM542a. Hook up + to + and - to - for the step and direction signals

Do not use the DM542a ENA signal at all.

When you say '24V logic power' do you mean power from the PSU that supplies 24V to my Field Power and also supplies the board with power? Should I connect the Mesa DIN rail common halves to the + and - coming from the field power terminal? or straight to the 24V PSU?
