SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
A08526 (F) PROFINET: No cyclic connection
Reaction: NONE
Acknowledge: NONE
Cause: There is no connection to a PROFINET controller.
Remedy: Establish the cyclic connection and activate the controller with cyclic operation.
Check the parameters "Name of Station" and "IP of Station" (r61000, r61001).
A08565 PROFINET: Consistency error affecting adjustable parameters
Reaction: NONE
Acknowledge: NONE
Cause: A consistency error was detected when activating the configuration (p8925 = 1) for the PROFINET interface. The
currently set configuration has not been activated.
Possible causes:
- IP address, subnet mask or default gateway is not correct
- IP address or station name used twice in the network
- station name contains invalid characters, etc.
See also: p8920 (PN Name of Station), p8921 (PN IP address of station), p8922 (PN Default Gateway of Station),
p8923 (PN Subnet Mask of Station)
Remedy: Check the required interface configuration (p8920 and following), correct if necessary, and activate (p8925 = 1).
See also: p8925 (PN interface configuration)
F08700 (A) CAN: Communications error
Reaction: 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 con-
troller.
- bus cable short circuit.
- 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.
Note:
The fault response can be set as required using p8641.
See also: p8604 (CAN life guarding), p8641 (CAN Abort Connection Option Code)
Remedy: - check the bus cable
- check the baud rate (p8622).
- check the bit timing (p8623).
- check the master.
The CAN controller must be manually restarted with p8608 = 1 after the cause of the fault has been resolved!

F08701 CAN: NMT state change
Reaction: 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: Not necessary.
Acknowledge the fault and continue operation.
