Programmable Parameters List | RoboteQ AX2850 guide

Configuring the Controller using the Switches

the controller. All parameters, including Joystick limits, will be reset to their default values shown in the “Programmable Parameters List” on page 174

Exiting the Parameter Setting Mode

Exiting the Programming Mode can be done only by pressing the Reset button or powering down the controller. The new parameters will be the ones in use after the controller is reset or first powered up.

Programmable Parameters List

The following table shows the AX2550’s controller parameters in the order they appear during programming, as well as their valid values.

Important Notice

The parameter table below is guaranteed to be accurate only if the controller soft- ware version number matches the one of this manual. See “Obtaining the Control- ler’s Software Revision Number” on page 23 for instructions on how to find this number.

This manual is for software version 1.9b

If the controller has a more current software revision, please download an updated version of this manual from the Roboteq web site at www.Roboteq.com.
