Hi all,

OK, next problem for all you clever people out there. After setting the default parameters from Grin for a GMAC motor using a 52v battery then running the AutoTune feature in Phaserunner I'm getting the following error:



A bit worrying for a brand new setup - or is it? Should I be concerned? I've only run this & tested outside briefly but the motor seems pretty juddery with both throttle & PAS, but I've not touched anything in Cycle Analyst yet as I wanted to be sure that there were no problems with my sensors before attempting any fine tuning.

Is there a problem with either my GMAC or Phaserunner do you think?

did you set the shunt the shunt to 1.000 ohm in the ca3?
have you tried autotune without ca3 connected

Hi goatman,

Yes, shunt is set to 1ohm in CA3. I've been doing some more testing, both outside & on rollers & both the PAS & Throttle seem very erratic - speeding up briefly for no reason & I've only been able to stop it by using the ebrake to kill the motor. Changing the motor position sensor type from (1)hall start & sensorless run to (2) sensorless seems to have improved things slightly, but it still seems to have a mind of it's own on occasion.

I've not tried Autotune without CA3 connected yet, I'll try it & let you know the results. Thanks for the suggestion.

Regards.

OK, tried autotune without CA3 attached & got the same error message. Looks like I got a dud GMAC eh? I've emailed Grin, I know they're off the scale busy, but hopefully I'll hear something from them in a day or two.

What a bummer.

i have one that wont turn off, and the transition from sensorless to sensored its rough, somethings going on with them or maybe the L10 connector????
