CAN Bus communication

Communication between the inverters and the higher-level controller takes place via a CAN bus 2.0 A (high-speed). CAN 2.0 A bus supports the 11-bit identifier format ('base frame format'). The 29 bit identifier format ('Extended frame format' called CAN 2.0 B) is not supported.

There are 2 variants available for data exchange:

Mode 'Fixed CAN message configuration'

Clearly defined CAN messages are implemented for exchanging data.

Mode 'Free CAN message configuration'

The data exchange between inverter and CAN controller can be configured by the user.

Configurable signals:

Process data from the list of SERCOS parameters: Siehe 'SERCOS parameter'.
Process data from the list of special signals: Siehe 'Special Signals'.

The operation mode 'Torque control' can only be implemented with the mode 'Free CAN message configuration'.
