CAN bus communication

What does 34 mean?

A message sent over the CAN bus was not acknowledged by another device on the network. This typically points to a communication issue, such as an incorrectly configured device, a disconnected bus, or a fault in the CAN network's physical layer. Loss of communication can prevent proper control and monitoring of the drive.
