I got the motor and controller installed and working on my 9x20 the other day.
The problem is the motor won't run until I turn the pot to top speed. Then I can slow it down, but if I turn the pot down too fast, the motor stops and won't go again until it's run up to full. It will run super slow and any speed in between. With the original slide pot from the treadmill, it won't start to run until it's turned up to 50%, then it can be slowed down. There are four adjustment pots on the controller. Labeled MIN MAX IR and CUR. IR and CUR have dabs of paint or glue to fix their positions. The controller is an ATR Manufacturing MC-40. It's from an old Cadence treadmil, circa 1995. Between the controller and DC motor it has a large choke coil, I assume to protect the controller from back EMF. I couldn't remove the flywheel because it's also the cooling fan and one piece with the multi groove pulley. Any way to tweak this so it'll start out slow as soon as the pot is turned off its low end? --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
