8.1: CAN Network
A CANopen network can support up to 127 nodes. Each node must have a unique and
valid seven-bit address (Node ID) in the range of 1-127. (Address 0 should only be used
when the amplifier is serving as a CME 2 serial port multi-drop gateway.)
Configure a CAN interface
Verify that the CAN network has been cabled and terminated as per amplifier documents.
Click CAN Configuration to open the CAN Configuration screen. (If CAN is
not the Position Loop Input, choose AmplifierNetwork Configuration instead.)
Choose network type (CAN or DeviceNet). This is optional for some drives.
Choose a Bit Rate and choose any combination of address sources (Switch, Inputs, and
Programmed Value). The address is the sum of the values from these sources.
For each source selected, perform the additional steps described below.
Verify the S1 switch setting. (Assigns values for Bit 0 – Bit 3 of CAN address.)
Enter Number of Inputs. Choose an input to represent each CAN address bit.
Enter the Programmed Value.
Click Save & Reset to save changes to amplifier flash, close the screen, and reset the
amplifier. Click Save & Close to save changes to amplifier flash without resetting.
NOTE: Address and bit rate changes take effect only after power-up or reset.
