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

Thanks- The Mentor II looks like it had a facelift! Do I need anything else in between my control input and the Mentor II? N

Hello again- After speaking with Electrol, they've told me that they've had sometime problems in the past with 50Hz. I wasn't able to gain an understanding about what they actually meant. Can anyone recommend an SCR drive that will work at 50Hz ? Also- is the modern motor control VFD? Or is...

Gunner, that was ridiculously helpful, thank you! Norad

I attached the FM that came with the drive. I'm using a 1/2hp motor with it. Should I be able to adjust it for 50Hz or do I need to purchase one made specifically for 50? 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...

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...

Hello- I'm using an SCR motor controller for a brushed DC motor 0-90VDC. The input power voltage to the SCR is 240VAC and it is rated for both 50/60Hz. The control voltage is 0-10VDC from a PLC. I've tested it at 60Hz, and it seems to work fine. At 50Hz, a branch breaker to the SCR blows...
