201912 <location>IF1: PB/PN clock cycle synchronous operation sign-of-life
failure
Message -
value:
Drive object: All objects
Reaction: OFF1
Acknowledge: IMMEDIATELY
Cause: The maximum permissible number of errors in the master sign-of-life (clock synchronous operation)
has been exceeded in cyclic operation.
Remedy: - check the physical bus configuration (terminating resistor, shielding, etc.).
- correct the interconnection of the master sign-of-life (p2045).
- check whether the master correctly sends the sign-of-life (e.g. create a trace with STW2.12 ...
STW2.15 and trigger signal ZSW1.3).
- check the permissible telegram failure rate (p0925).
- check the bus and master for utilization level (e.g. bus cycle time Tdp was set too short).
Note:
IF1: Interface 1
PB: PROFIBUS
PN: PROFINET
201913 <location>COMM INT: Monitoring time sign-of-life expired
Message -
value:
Drive object: All objects
Reaction: A_INFEED: OFF1 (NONE, OFF2)
SERVO: OFF1 (NONE, OFF2, OFF3)
VECTOR: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The monitoring time for the sign-of-life counter has expired.
The connection between the drive and the higher-level control (SIMOTION, SINUMERIK) has been
interrupted for the following reasons:
- the control was reset.
- the data transfer to the control was interrupted.
Remedy: - wait until the control has re-booted.
- restore data transfer to the control.
201914 <location>COMM INT: Monitoring time configuration expired
Message %1
value:
Drive object: All objects
Reaction: A_INFEED: OFF1 (NONE, OFF2)
SERVO: OFF1 (NONE, OFF2, OFF3)
VECTOR: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The monitoring time for the configuration has expired.
Fault value (r0949, interpret decimal):
0: The transfer time of the send configuration data has been exceeded.
1: The transfer time of the receive configuration data has been exceeded.
Remedy: - acknowledge faults that are present.
- carry out a POWER ON (power off/on) for all components.
- upgrade firmware to later version.
- contact the Hotline.
201920 <location>PROFIBUS: Interruption cyclic connection
Message -
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
