I have two new Votol EM150s here but cant either to show any life. I am running on 48v.
I cant connect to PC, have tried two different PCs. Have tried two different cables to the PC.
All I get is showing connected but then "Communication abnormal no response"
I have the B+ and B- connected and the elock connected.

When connected to the motor, throttle output is showing correct to the ccontroller but no response form motor
It seems the controller is dead but this applied to both these controllers.
Any one can help? Driving me nuts.
Appreciate any help.
