Device Reactions - Power Supply

Overview

Diagnostic messages triggered by a power supply have an additional device reaction. In the following table, the device reactions are sorted according to their priority (from High to Low).

  • Informing message to PacDrive controller.

  • The program can be used for controlled, synchronous shutdown.

  • If the PacDrive controller does not trigger any reaction in the drive, a diagnostic message with the device reaction AP, BP1, or BP2 may occur.

Message

For this device reaction there is no diagnostic message defined by default.

The device reaction can be reconfigured using the function FC_DiagConfigSet2 or FC_DiagConfigSubClassGroupSet. The priority of the configured device reaction must always be equal to or greater than the priority of the minimum device reaction. The minimum device reactions are indicated in the respective diagnostic message and in the overview table.
