Abstract
A safety-rated industrial device, such as a motor drive, is provided with a safety subsystem that is initially bypassed as a factory default mode. While the safety subsystem is disabled, the device operates as a standard non-safety device, allowing users to perform operations with the device (e.g., turning a motor in the case of motor drives) without requiring safety input devices or a safety controller to be connected to the device. The device continues to operate as a standard non-safety device until a proper safety configuration is applied to the device, whereby the device's safety subsystem is retentatively enabled and the device begins operating as a safety-rated device. While the safety subsystem is enabled, certain device operations that were permitted during standard mode independently of an attached safety controller or safety input devices are made contingent on the monitored status of an associated safety system.
