![]() Well I can't be certain but I have seen enough to know that unless you have a good tune between drive and motor then you are not going to get a good tune between the IP-A and the drive. I thought the axis using the 20 year old servo card was going to be the issue, not this one with the modern drive! ![]() The motor screw ratio is 1:1.5, 6mm pitch b/screw, but it is a proven system from the previous control incarnation. By that I mean I can twist the ballscrew pulley from 11 o'clock to 2 o'clock with little resistance. After auto tuning several times the best I can achieve still leaves very slight ocilation/hunting and next to no rigidity. It's an Axor MCS 110 6/12amp.Īfter wiring it in I'm struggling with the tuning config. Today I received a new servo drive for the X axis as the old amp died. Smooth, no hunting, repeats accurately, everything is great. Last night I very quickly tuned the Z axis which is being driven off the existing servo amplifier 100v DC. I've used a CSMIO A type to drive the existing hardware, brushed DC servo motors with encoder feedback going straight to the CS module. I've started another thread talking about retro fitting a ROMI lathe with mach3, which had Bridgeport EZ PATH on.
