But, the customer already HAD the Gecko 320 drives running in open loop step/servo mode, but wanted encoder feedback to the PC. Using the Gecko Interface is cheaper than replacing the drives with my PWM servo amps. And, still, you might not have totally reliable runaway detection even with that, but the saturated PID detection OUGHT to work there. > All kidding aside---thanks for an elegant solution, Jon. > Well, not really elegant, but I think it would work, and not require months of firmware design.
