I'm working with a KLS7218M controller. I've wired the contoller to a 48 volt source and to the electric motor. The controller drives the motor as expected with default settings, but my computer will not recognize the controller so I cannot program it
Specifically, I have downloaded and installed the SM-4A to USB Converter driver from Kellycontroller.com, and downloaded the KMC user app. I connect the controller to my computer via an SM-4A to USB adapter cable. I run the KMC user app, select "yes" to confirm that the motor is not running, and then receive the "Controller no power or RS232 cable disconnect error." I have seen this error referenced in several places, including in Joe Yamazaki's youtube video: https://www.youtube.com/watch?v=bIWAlT1sgEk. The only advice I have seen is to cycle the power to the controller and keep trying until it connects. I have tried ~dozen times without success.
I have also tried uninstalling and reinstalling the SM-4A to USB Converter driver, installing the RS232 to USB drivers, changing the SM-4A to USB cable, and disconnecting the U, V and W leads from the controller to the motor. None of these steps have affected the software errors. I have measured voltage between the black and read pins in the SM-4A controller and see over five volts.
Does anyone have advice on how to get past the "controller no power" error?
Thank you!
