2008 E4 Factory Programming Settings

Ya, if only there was a way to make it so ‘users’ didn’t have to enter the decimal value for 8 bits(11111111 = 255) but instead could enter a percentage like 100. Especially when the software is already quite clunky. :wink: More resolution with 0-255 as opposed to 0-100 I presume.

Users of this software probably don’t really mentally map the numbers to anything tangible anyways but it’s likely there’s a little 8 bit MCU inside these Controllers so everything is in the range of 0-255.

I also had forgotten that I too put together a spreadsheet of settings but was asked not to publish it to prevent Joe Sixpack from blowing up his GEM.

Post the minimum recommended field current.
Not dangerous and the only setting to make motor overheat. I think.
Can brushes cause heat? I think not. Fire yes, but not heat. :slight_smile:
Did anyone look at the settings linked to above?

I am sorry. Yes, that was a typo. It was 255 indeed.
