Functional Description

Information on the Module Bus

The module bus establishes the exchange of signals between the

inverters or converters or from the inverters to the supply unit.

Independent of the master communication, this allows the devices to

exchange information on internal status variables of the drive system and

error situations without delay. Axis drives and supply units can therefore

react in a coordinated way.

The module bus transmits the following information:

• With regard to the supply unit:

• supply unit ready for operation

• ready for power output

• DC bus voltage in or outside of allowed range of values

• warning against overload of supply unit

• signal for resetting supply errors

• With regard to inverters or converters

• inverters or converters ready for operation

The status information transmitted by inverter (IV), supply unit (SU) or

converter (CV) to the module bus has a hierarchical order.

Fig. 6-57: Module bus status information and hierarchy

If several parts of status information from one or several module bus

nodes are present at the same time, the status information highest in

hierarchy determines the signal status of the module bus.

Error messages of supply unit output via:

• display of supply unit

- and -

• inverter or converter connected at module bus (collective error
