Module bus fault description
The module bus master sends all occurring fault messages to the connected module bus stations (slaves) using the module bus. The faults are divided into 3 categories (warning, standard fault, critical fault). There are 2 fault transmission modes (normal, warning) available, see chapter "Module bus – fault transmission". In the case of system states that may destroy or damage the axis system, it is important that the output stages of the drives can be inhibited quickly. For this purpose, the module bus offers emergency shutdown, see chapter Module bus – emergency shutdown. If necessary, the module bus communication in the device can be partially deactivated. This means the module bus data in the device is not evaluated, the module bus communication however proceeds if module bus stations are connected to each other. For safety reasons, the device responds to the emergency shutdown.
