SFA-5000 • SFA-10000 CANopen®

100C-00 Guard time

: interval between two RTR messages.

Node life time

maximum time available for the encoder to receive an
RTR message.

Node life time

100C-00 Guard time



100D-00 Life time factor

“Node guarding” is enabled if

Node life time



If the Slave does not receive an RTR message before the

Node life time

has

expired, it warns activating a “Life Guarding Event”. Furthermore the red LED
starts flashing so indicating the Node guarding error (see on page 34),

1001-00

Error register

and

1003 Predefined error field

objects are updated and an

error message is sent.
To reset the error send a

Reset node

command.
