02.2004 Communication / CBC CANopen Communication Board
Siemens AG 6SE7087-6QX70 (Version AD)
SIMOVERT MASTERDRIVES Compendium Motion Control 8.5-101
Error Meaning
F 080 TB/CB Initialization fault:
CBC is incorrectly initialized and parameterized via the dual port RAM interface (DPR
interface)
• Error in CBC parameter(s), cause of parameterization error
in diagnostic parameter r732.01
→ Correct CB parameter P711-P721
Correct CB bus address P918
• CBC defective
→ Replace CBC
Note: If the MASTERDRIVES boots with an error F80, the parameter channel is
disabled. MASTERDRIVES cannot then process any SDO tasks.
F 081 OptBrt heartbeat counter:
The CBC has ceased processing the heartbeat counter.
• CBC incorrectly inserted in the electronics box
→ Check CBC
• CBC defective
→ Replace CBC
F 082 TB/CB message failure:
The message failure monitoring time set in parameter P722 has run out.
NOTE: The message failure monitoring time should be set to 0 for CANopen since data
are not always exchanged cyclically and message failure is monitored by the node
guarding function.
• CAN bus master has failed
(green LED on CBC is off; with cyclical data exchange only)
• Cable connection between bus nodes interrupted
(green LED on CBC is off)
→ Check bus cable
• Electromagnetic interference on bus cable too high
→ Observe EMC guidelines
• Message monitoring time is set too short
(green LED on CBC flashing)
→ Increase parameter value in P722
• CBC defective
→ Replace CBC
