Mapping Alltrax SPM400
My cart is a 2001/2002 Series TXT 36V. 20 Inch tall tires, 6:1 rear end, high speed D&D Motor, HD F&R, 1/0 Gauge cables, 400/1000 SD Solenoid, and Leaf Lithium battery pack.
Replacing my burnt Alltrax AXE 4855 with Alltrax SPM400 this week. I use the cart for golf. Have high speed motor and 6:1 gear because my house is a long way from clubhouse and wanted the speed. I didn't mess with the AXE programming when I installed it 4 years ago, but it seems like the SPM will be easier in that respect. Any suggestions on if I should change settings (more torque/acceleration to start, etc.) for my usage? Thanks |

Re: Mapping Alltrax SPM400
you mean a SPM 48500 right?

Re: Mapping Alltrax SPM400
Let's put this into perspective.
Your cart's mechanical torque loss is about 60%. (About minus 10% for the 20" tire height and about minus 50% for the 6:1 gears.) You have a high speed motor. (Which by design, sacrifices low end torque for higher speed. Could be 15% or more torque loss at low end.) You replaced a 500A controller that failed with a 400A controller. (A 20% reduction in torque.) Now you want to know if the are any user programmable settings in a SPN48400 that will give you more torque and acceleration off the line. (Which are basically one and the same.) The answer is maybe, but not much. That set-up (Tires height - Gears - Motor) is going to be slower than molasses in January off the line. Suggest you contact Alltrax and D&D for their recommendations as to what the SPM setting should be. |

He's also lighter with that lithium pack.

Re: Mapping Alltrax SPM400
Johnnie is painting a pretty grim picture. I know there are some suppliers out there saying a SPM400 is equal to the old AXE500 and costs less money. They make a lot of sales this way. I understand their argument. While peak is 10% less, the sustained output is actually greater from the 400 than the 500. But that's a 1 hour test and what we are talking about here is off the line power.
Interestingly enough there are torque and voltage curves available for customization in the SPM software. |

Re: Mapping Alltrax SPM400
Since the Alltrax can accept up to 60v max why don't you run 7 Leaf modules in series for 53v nominal (58.8v max)?

Re: Mapping Alltrax SPM400
I would only talk to AllTrax about adjusting the settings. In my conversations with folks at D&D they are not a fan of adjusting things at all, they like to see a linear curve / default setting.
