I have an Optima 2080 which I am just putting together and learning to use. I have connected a brushless servo amplifier that uses standard +/- 10v analog signal for control. The only two wires connected to the amplifier from the control are the +/-10v, and the AMPEN (inhibit on the amplifier) wire. It seems to work just fine, and I can control it from the terminal program after tuning it, but if I give the MO command the motor just takes off running at max speed and wont stop until I give an SH command or reset.

I am not using an interconnect module, just wiring directly from the 100pin port.

Any ideas?

Thanks

Never mind... I connected the signal ground back to the controler and the AMPEN signal now works. I had originaly disconnected it because it had caused the amplifier to fault when I first connected it to the controller, and then worked fine without it. I guess the controller must have had the MO command active at that time without my knowledge.

the thread is not viewable. Is it because it is too old? How can I read it?
