    What is the difference between tachometer input and 0-10V (or 05V) input. Can I use the tach input in the same way? Thank you for replies- N

The seller of the drive told me it was rated 50/60 but they just told me they cannot test it at 50 because they don't have...

    SCR motor control

    Thanks. Unfortunately there is no M to FR. It is circa early 1990s so probably analogue. I don't actually know how it works. The only ramping available are potentiometers on the board. I can write ramping into software. There is also a pot for IR Comp. Any idea what that is? Any thoughts on...
