Overview of Alarms
SINAMICS-Alarms
Remedy: - check the bus cable
- check the baud rate (p8622).
- check the bit timing (p8623).
- check the master.

208700 <location>CBC: Communications error
Message %1
value:
Drive object: A_INF, B_INF, S_INF
Reaction: A_INFEED: NONE
SERVO: OFF3 (NONE, OFF1, OFF2)
VECTOR: OFF3 (NONE, OFF1, OFF2)
Acknowledge: IMMEDIATELY
Cause: A CAN communications error has occurred.
Fault value (r0949, interpret decimal):
1: The error counter for the send telegrams has exceeded the BUS OFF value 255. The bus disables
the CAN controller.
- bus cable interrupted.
- bus cable not connected.
- incorrect baud rate.
- incorrect bit timing.
2: The master no longer interrogated the CAN node status longer than for its "life time". The "life time"
is obtained from the "guard time" (p8604[0]) multiplied by the "life time factor" (p8604[1]).
- bus cable interrupted.
- bus cable not connected.
- incorrect baud rate.
- incorrect bit timing.
- master fault.
See also: p8604 (CBC node guarding), p8641 (CBC abort connection option code)
Remedy: - check the bus cable
- check the baud rate (p8622).
- check the bit timing (p8623).
- check the master.

208701 <location>CBC: NMT state change
Message %1
value:
Drive object: A_INF, B_INF, CU_LINK, CU_S, HUB, S_INF, SERVO, TB30, TM15, TM15DI_DO, TM17, TM31,
TM41, TM54F_MA, TM54F_SL, VECTOR
Reaction: A_INFEED: OFF2
SERVO: OFF3
VECTOR: OFF3
Acknowledge: IMMEDIATELY
Cause: A CANopen NMT state transition from "operational" to "pre-operational" or after "stopped".
Fault value (r0949, interpret decimal):
1: CANopen NMT state transition from "operational" to "pre-operational".
2: CANopen NMT state transition from "operational" to "stopped".
Note:
In the NMT state "pre-operational", process data cannot be transferred and in the NMT state
"stopped", no process data and no service data can be transferred.
Remedy: None necessary.
Acknowledge the fault and continue operation.
