4.2 List of faults and alarms
A01514 (F) BICO: Error when writing during a reconnect
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: During a reconnect operation (e.g. while booting or downloading - but can also occur in normal operation) a
parameter was not able to be written to.
Example:
When writing to BICO input with double word format (DWORD), in the second index, the memory areas overlap (e.g.
p8861). The parameter is then reset to the factory setting.
Alarm value (r2124, interpret decimal):
Parameter number of the BICO input (signal sink).
Remedy: Not necessary.
F01515 (A) BICO: Writing to parameter not permitted as the master control is active
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: When changing the number of CDS or when copying from CDS, the master control is active.
Remedy: If required, return the master control and repeat the operation.
A01590 (F) Drive: Motor maintenance interval expired
Message class: General drive fault (19)
Reaction: NONE
Acknowledge: NONE
Cause: The selected service/maintenance interval for this motor was reached.
Alarm value (r2124, interpret decimal):
Motor data set number.
See also: p0650 (Actual motor operating hours), p0651 (Motor operating hours maintenance interval)
Remedy: carry out service/maintenance and reset the service/maintenance interval (p0651).
F01662 Error internal communications
Message class: Hardware/software error (1)
Reaction: OFF2
Acknowledge: POWER ON
Cause: A module-internal communication error has occurred.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (switch-off/switch-on).
- check the electrical cabinet design and cable routing for EMC compliance
- check whether an impermissible voltage is connected at one of the digital outputs.
- check whether a digital output is loaded with an impermissible current.
- upgrade firmware to later version.
- contact Technical Support.
A01900 (F) PROFIBUS: Configuration telegram error
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: A PROFIBUS master attempts to establish a connection using an incorrect configuring telegram.
Alarm value (r2124, interpret decimal):
2: Too many PZD data words for input or output. The number of possible PZD is specified by the number of indices in
r2050/p2051.
3: Uneven number of bytes for input or output.
211: Unknown parameterizing block.
Additional values:
Only for internal Siemens troubleshooting.
