Default Controller Configuration

Version 1.9b of the AX2550 software is configured with the factory defaults shown in the table below. Although Roboteq strives to keep the same parameters and values from one version to the next, changes may occur from one revision to the next. Make sure that you have the matching manual and software versions. These may be retrieved from the Roboteq web site. See “Configuring the Controller using the Switches” on page 171 of the User Manual for a complete configuration parameter list and their possible values.

TABLE 2. AX2550 Default Settings

Parameter	Default Values		Letter
Input Command mode:	(0)	= R/C Radio mode	I

Motor Control mode	(0)	= Separate A, B, speed control, open loop	C

Amp limit	(5)	= 105A	A

Acceleration	(2)	= medium-slow	S

Input switch function	(3)	= no action	U

Joystick Deadband	(2)	= 16%	d

Exponentiation on channel 1	(0)	= Linear (no exponentiation)	E

Exponentiation on channel 2	(0)	= Linear (no exponentiation)	F

Left / Right Adjust	(7)	= no adjustment	L

Any one of the parameters listed in Table 2, and others not listed, can easily be changed either using the controller’s buttons or the PC with the Roboteq Configuration Utility. See “Using the Roborun Configuration Utility” on page 177.

The example below shows how to use the buttons to select and change the Motor Control mode from “separate” to “mixed”. See “Configuring the Controller using the Switches” on page 171 of the User’s Manual for a complete list of all the AX2550’s parameters and their meanings.
