Description

For a CAN network with several drives connected, there is an option for using a serial connection to one of the devices (master) to communicate with all the other amplifiers. To do this, the SCAN command is initiated on the master device, which performs an automatic detection of all the drivess that are connected. The response to the SCAN command contains the total number and a list of the addresses of all the drive devices that have been detected.
The time taken to carry out this command is strongly dependent on the baud rate (CBAUD) that is has been set for CAN, and is in the range from 1 second (at 1 Mbaud/1 Mbps) to 37 seconds (at 10Kbaud/10 kbps).
With drive 400, the communication is not done via CAN, but via an internal serial link. The behaivior is the same.
