installed tooling is clear of all obstructions.
Remote Brake Release Feature
You can also configure the XIO Input 6.2 (pin 18) to act as an alternate hardware brake release
input. The setting is available on the Robot page in the ACE software. The parameter is
Remote Brake Release Input. When enabled (True), activating XIO Input 6.2 is identical to
pressing the brake button on the status display. The input status will still reflect in the IO
