Cannot Run Motor Backwards

5 years 7 months ago #29533230 by GranMan
I recently acquired an SBL1360. The driver has been updated to the most recent available firmware and I am running the latest version of Roborun+ on the computer from which I control it.

I have a 3 phase,12 pole pair, BLDC motor which I am attempting to make run. It is important to my project than the motor can run forward and backwards comparably well. I am using closed loop speed mode with the 3 built-in hall sensors in the motor. When I run the motor for positive motor command values (drag the slider to the right), the motor starts and stops properly, reaching correct speeds with reasonable currents. However, when I send negative motor command values (slider to the left of 0), the motor stalls and the controller seems to dump current (in excess of 5 amps when the same speed setting in the other direction consumed less than a single amp) and stall.

Why can I not run my motor equally well forwards as backwards?

Why does Roboteq not give you any support???

Does it work well in open loop mode? Are the hall-sensors counting the right way if you turn the motor manually? So they count up and down if you spin the wheels by hand?
