RoboteQ AX2850 user manual Activating the Accessory Outputs

R/C Operation

Notes:

If you attempt to calibrate the joysticks while the radio is off or not connected to the con- troller, the calibration data will not change and the previously stored information will con- tinue to be used.

If calibration is performed with only one R/C channel connected to the controller, then only the joystick that is active will be calibrated. The other channel will keep its original settings.

A minimum amount of travel is required between the min, max and center joystick posi- tions. If, while calibrating, the joystick has not been moved far enough from either side of the center position, the controller will automatically include a minimum of travel to ensure proper and safe operation. In most cases, this creates no undesired effect to the driving characteristics of the robot.

R/C calibration only applies to the channel 1 and channel 2 inputs. The accessory activation channel (channel 3) is preset at the factory and cannot be changed.

Important Notice

To ensure that only stable pulses are present, the R/C transmitter and radio must be

On before entering joystick calibration.

Activating the Accessory Outputs

The AX2550 has a general purpose output that may be turned on and off using a third R/C channel on the radio.

Output C is a buffered output capable of driving a 2A device at up to 24V. Details on how to wire this output to user accessories can be found at “Connecting Sensors and Actuators to Input/Outputs” on page 55.

The output is activated by pushing the joystick to the maximum position. The output turns back off when the joystick is returned to the center position.

Note: Channel 3 is not available on the controllers equipped with encoder inputs.
