11.1 General information
For many years, the system bus (CAN) based on the CANopen communication profile has been
integrated in Lenze inverters. Due to the lower number of data objects available, the functionality
and compatibility of the previous system bus are lower as compared to CANopen. For parameter
setting, two parameter data channels are always available to the user while CANopen provides only
one active parameter channel.
The system bus (CANopen) of the Inverter Drives 8400 is a further development of the system bus
(CAN) including the following properties:
• Full compatibility with CANopen DS301 V4.02.
• Support of the "Heartbeat" NMT slave function (DS301 V4.02)
• 1 or 2 parameterisable parameter data channels for transmitting SDOs (Service Data Objects)
• Up to four parameterisable process data channels (dependent on the device version) for
transmitting PDOs (Process Data Objects)
• All process data channels are functionally equivalent
• Monitoring of the receive PDOs for data reception
• Adjustable error response to ...
• physical CAN errors (frame, bit, ACK error)
• bus-stop, bus working
•absent PDOs
• Telegram counters for SDOs and PDOs
• Bus status diagnostics
• Boot-up telegram generation
• Emergency telegram generation
• Reset node telegram generation (for master configuration)
• Sync telegram generation and response to sync telegrams:
• Data transmission/reception
• Device-internal time base synchronisation
• Abort codes
• All CAN on board functions can be parameterised via codes
• Object directory (all mandatory functions, optional functions, indexes)
