Hello, I have a NSK ESA Y2020 drive that appears a blown optoisolator on the quadrature encoder output. The A, B, B*, Z and Z* channels work normaly, with a zero to five volt throw, but the A* channel only has about a half volt thow. Of course this is preventing it from working properly. Can you offer an estimate? I am waiting for the drive back from the intigrator, but will be able to send the unit when it arives.Thank you in advance.Scott
