Error E 8141 on a Lexium32 servo drive

Description: CANopen: CAN controller is in 'bus-off' state

Cause: Too many error frames have been detected, CAN devices with different baud rates.

Correctives: Check CAN bus installation. Most of the time, the problem is because cables and junction boxes that are not CANopen rated are used. Make sure that the network has two 120 ohm terminating resistors at both ends of the network. If the length of the network is long verify that the baud rate supports that length:

Speed in bit/s  - Maximum Cable Length
1 Mbit/s - 20 m (65 ft)
800 kbit/s - 40 m (131 ft)
500 kbit/s - 100 m (328 ft)
250 kbit/s - 250 m (820 ft)
125 kbit/s - 500 m (1640 ft)
50 kbit/s - 1000 m (3280 ft)
