HOW TO PICK A MOTION CONTROL BOARD

OK thats good so L5 need not be connected since all the channels get
their line sync from the control transformer that runs the +- 15V supply

But I'm stumped. I will look at the manual if I get a chance
tomorrow and see if any other obvious things to check jump out at me.
Wonder is theres a full schematic available anywhere?

I haven't been able to find a full schematic, but I will try to get a hold of Indramat tomorrow and see if they have anything.



Here's the service manual to the machine. Page 33 "Servo Amplifier Interface" to Page 44 has schematics. I found these today, but I'm not sure they are helpful.

I'll keep looking too. Also I'm not sure, but could a limit switch or E-Switch cause this inactivity?

OK so a looking at (pdf) page 39, is CR2 (servo power contactor) on? If you have Estop or other faults this may be off

I looked tonight and the E-Stop button was pushed in, so I pulled it out and tried to power on the drive again, nothing changed. I measured voltage on U1, U2, V1, V2 where CR2 says it connects to the 3TRM2, those terminals had no voltage on them. I traced the wires back to what I think is CR2 and there seems to be some issue here. I get power on one side of this device, but not on the other, plus there are two small wires connected to it like some sort of control. If I push the relay in, the power distributes down to the U1, U2, V1, V2, but gives me no ready lights or anything.


I added a picture of what I think CR2 is, I followed the wires from U1,U2,V1,V2 here. It is the black device. There is power on the right side and nothing on the left, unless you push the middle of it in.

cr2 is a power contactor relay ,the small wires you see are infact the coil of the relay , i'd check any estop circuits or limit switches , guards etc , open doors .
have you found a full wiring diagram as yet ?

I'll look into the E-Stop circuits tonight, I think page 40 has it.

I haven't found a full schematic on the 3TRM2 yet.
