Basic CANopen
What are the advantages of distributed control?
Less wiring, management and monitoring of amplifier status. Overall reduced cost of ownership after everything is assembled. Less EMI.
What is the function of the 120 Ohm resistors?
To maintain the line impedance and noise immunity.
How long does it take to send a PDO message when the baud rate is 500,000 b/s?
About 5 kbps x 100 = 200 µs
What is the binary interpreter method?
The storage and execution of Elmo commands on PDO2.
What will be the COB-ID if I want to send a message to the drive by the binary interpreter to node ID 93?
0x35D
What is the meaning of the message with COB-ID 0xAF?
Node ID 47 sends an emergency message.
How the does heartbeat mechanism carry out its function?
It pings/polls the CAN bus for the status of Node IDs
Which type of messages require an acknowledgement?
Confirmed messages, usually SDOs
What will be the boot up message for node ID 83?
0x753 – an error message
