Activating Brake Release or Separate Motor Excitation

The controller may be configured so that the Output C will turn On whenever one of the two motors is running. This feature is typically used to activate the mechanical brake release sometimes found on motors for personal mobility systems. Likewise, this output can be used to turn on or off the winding that creates the armature’s magnetic field in a separate excitation motor. This function is disabled by default and may be configured using the Roborun PC utility. See “Loading, Changing Controller Parameters” on page 181. See “Connecting devices to Output C” on page 59 for details on how to connect to the output.

Emergency Shut Down Using Controller Switches

In case of emergency, it is possibly to cause the controller to cut off the power to the motors by depressing the Program and Set buttons simultaneously as shown in the figure below. The controller will stop immediately without delay.

Emergency Stop using External Switch

An external switch can be added to the AX2550 to allow the operator to stop the control- ler’s output in case of emergency. This controller input can be configured as the “Inverted” detection instead of Emergency Stop. The factory default for this input is “No Action”.
