7 Preparing the field devices
7.1 Installing field devices
Install the field devices according to the data given in the device-specific mounting instructions.
Make sure that ...
• the CANopen installation complies with your overview screen.
• all devices are supported by the control technology system on the Logic bus and Motion bus.
• in the case of devices with several CAN interfaces, the correct interfaces are connected to the
fieldbus.
• a terminating resistor is connected to the first and last node.
• the fieldbus is not unintentionally interrupted in switchable CAN connectors.
7.2 Setting node addresses and baud rate
• Set the specified node address and baud rate on the field devices via DIP switch (if available on
the device), or via parameter/code.
• Mark the devices the settings of which you have changed in your overview screen.
• Attach address labels to the devices.

Note!
• Each node address must be unambiguous and may only be assigned once in the
CANopen network.
• The baud rate must be set identically for all nodes.
• Observe the connection between bus cable length and baud rate.
 Bus cable length ( 22)
Configuration via the »WebConfig«/»EASY Starter« for the Lenze Controller/IPC
If the baud rate has been changed via the »WebConfig«, the Lenze Controller/IPC needs
to be restarted afterwards. Then an online connection to the CAN nodes can be
established with the »EASY Starter«.

Information on the DIP switch settings can be found in the documentation for the field
devices.
