Hi All,
I am converting a Deckel mill to EMC using the Mesa 7I37 TA, 5I23, 7I33 TA and AMT-2 encoders. The motors are DC brush type with a Siemens control.
I have a problem with the 7I33T card connections to my Amp. I have four input wires to the Amp
Earth wire
Wire from a relay
Two wires from the old controller. One of these wires must go to the +- 10V (pin 10 on the 7I33Tcard) where do I connect the other wire from the controller? Are the GND wires on this card all common? (Pins 9,11,21,23) Someone suggested I earth that wire, just want to be sure before I damage something.
Regards
