AX2500/2850 Motor Controller User’s Manual 51
AX2500/2850’s Inputs and Outputs
AX2500/2850’s Inputs and Outputs
In addition to the RS232 and R/C channel communication lines, the AX2500/2850 includes
several inputs and outputs for various sensors and actuators. Depending on the selected
operating mode, some of these I/Os provide feedback and/or safety information to the con-
troller.
When the controller operates in modes that do not use these I/O, these signals become
available for user application. Below is a summary of the available signals and the modes in
which they are used by the controller or available to the user.
