10 Lost Communication Trip
Supervised Parameter:
The
0777 Comms Supervised
parameter indicates that the CANopen network participation is supervised
by another CANopen device.
The Supervised parameter value is set to TRUE when either:
The heartbeat consumer and Heartbeat producer is enabled and error free.
Node guarding is enabled and error free.
Comms Break Trip
The drive will trip when there is a loss of communications between the master and the drive.
A COMMS BREAK trip will occur if the
0777 Comms Supervised
parameter transitions from TRUE to
FALSE and the drive is in the operational state.
The trip may be disabled by clearing the respective bit in the parameter
0870 Enable Trips Lo
. The
parameter Enable Trip Lo is a 32-bit word, the bit number 27 is used to disable or to enable the trip.

indicates ‘PROCESS_ACTIVE’ when the CANopen communication is
active. The table below describes how the comms state relates to the CANopen network:
