Kenny,
I found this in the manual for the drive. The drive has a "0" position marker pulse it outputs, but the pulse comes out on a separate terminal then the main channel a/b. As far as I can tell, the signal is not included on channel a/b. Is the Galil looking for this index pulse on the A/B channel?
BTW, I am using SFD feedback as mentioned below.
From the Danaher S200 Drive Manual ""The CH Z Output is only available when using SFD
Feedback. These two terminals function as a differential,
TTL marker pulse. The output pulse occurs once per
motor shaft revolution, starting at feedback device
position = 0. Its width is one line width or two quadrature
encoder widths. The CH Z uses the same differential
driver as described for CH A and CH B.""
Could this "Z Channel" be connected into the Galil? How?
Thanks
