Controller Pro Software
Alltrax Motor Controllers:
Communications Software
The Programmable Alltrax Electric Motor Controllers such as the AXE
(Series wound motors) and the DCX (Shunt wound motors) include an
RS232 communications port. This port can be used to adjust user
settings such as throttle type, power settings, and speed settings. It can
also be used to monitor operation of the controller real time.
The program runs on Microsoft Windows(TM) based machines, laptops or
desktops using simple user friendly controls. Alltrax provides this
software down-loadable free of charge (cables not included). Controller
Pro software has not been run on MAC(TM) based machines.
A kit can be purchased from Alltrax which includes:
- Communications cable - RS232 to USB adapter
- CD-R with Controller PRO operators manual, tech-notes, and the
Controller PRO software program
- Wall wart (120 VAC 60Hz transformer) supplies 15-20 VoltsDC to
power the logic for programming. (International 220VAC 50Hz
input to 15-20 VoltsDC transformers also available)
- Instruction Manual & Technical notes (Available from web site)
- Free technical support

AXE and DCX Models Only - Prevent motor controller from providing power if throttle is applied prior to Key Switch Turned on
|
|
|
AXE "P" and DCX models ONLY with A2 terminal lug. Provides Plug Braking proportional to throttle position reaching ful "Plugging" (Dynamic Motor Braking) when throttle below 25%.
|
|
|
Provides higher seed when not in current limit and throttle is at 100%
|
|
|
ACXE and DCX Models Only - Limits vehicle speed in reverse based on 50% of forward "Top Speed" setting.
|
|
MAX OUTPUT CURRENT (0-100%)
|
|
0-100% adjustment limits max current supplied to motor. Used to limit power. (The 400A controller set to 50%=200Amp max)
|
|
|
Sets the under voltage where the unit limits power and eventually shuts off. Prevents battery damage
|
|
|
Sets the over voltage shutoff for the controller during excessive regen or overcharging to prevent damage
|
|
THROTTLE UP RATE (1-15, Default 4)
|
|
Determines the rate of controller output power based on an INCREASE in throttle input. Setting 1=slow, 15=Fast.
|
|
THROTTLE DOWN RATE (1-15 Default 4)
|
|
Determines the rate of controller output power based on an DECREASE in throttle input. Setting 1=slow, 15=Fast
|
|
|
>AXE "P" Models - Adjusts the amount of Plug Brake Current as a percentage of 100A of brake current
>DCX Models - Regeneration Feature is a percentage of possible current available
|
|
|
Sets the top speed as a percentage of top-speed

The AXE and DCX are user programmable controllers with the RS232 port available to
the user.
The NCX and NPX Controllers are cost effective Stock Replacement controllers that are
factory programmed only. However, they include many of the same features listed
below (just not accessible in the field).
Did you know?
> The ALLTRAX
Controllers can be
programmed on your
bench using a small
power supply? This
makes life easy when
installing new units in
your cars application.
Did you know?
> Controller-Pro can
function like a DATA
LOGGER? Connect your
laptop and set the
"Monitor" to save real
time data to your hard
drive.
The Controller Pro software is broken into three tabs, Control / Throttle / Monitor. The
controller must powered up before the screens will supply data. For more details on
supplying power - see the [Download Drawing] link shown above.

Corrects Throttle Glitch caused by noisy communications cables
|
The Controller Pro software Build 39, Ver 2.2 will properly read and write the throttle curve
In some cases, noise from communications cables from the various computers, laptops, and desktops were found to create noise in the throttle table. This version 39 requires the controller to resend the throttle and verify it is correct
Please download and replace your Controller Pro update to include the new Model number
