Figure 6.7 CANopen Error indicator
When the Error indicator is off the drive is CAN bus is working with no problems. When the number of error
frames on the CAN bus has reached the warning level there is one short flash with a one second pause on the Error
indicator. When the controller suspects it is the source of the error frames it goes bus off automatically. This is
indicated by the Error indicator on continuously.
In case of a guard event or a heartbeat event the Error indicator is flashing twice with a one second pause.
When a Synchronisation message hasn't been received in time this is indicated with a triple flash and a one second
pause.
