do you have the electrical wiring drawings for this machine?
it would help a lot to figure out what you need to bridge out and what power you need to supply to run the servo drive / motors.
Ok i have figured out the circuit somewhat from the previous attachments. Kindly correct me if i'm wrong. Spent some time also checking the drives.

E1A, E1B are inputs from D/A +/-10V, similarly E101,102, 201,202,301,302. These go to a differential pre-amplifier. So I connected a small 1.5V battery to E1A and GND. I can connect to either right?
E2?E3? still don't know, these go to the TSS8 mounted module
RF- is Control Release, I need to provide (5V-30V), connected +24VL available on drive itself. Multimeter reads 29V

P-Eing? is this potentiometer tuning
in 3TRM2 Page 19-
Both JF's and RF are shorted? Pulse release and control release where i already gave 29V. But still nothing. Did with all three drives along with 1.5V. The switch d1 (bottom right in 1TRM3 pic attached pdf) with contacts Bb1(NC), Bb2(common), Bb3(NO) didnt enable. Tried shorting this and then also giving 29V at RF/JF still nothing, Red LED not Green :confused:
What am i missing. See attached pdf w/t pics and wiring in diagrams. Its in German though. Page 3 3TRM2 (7A1)
