List of Faults and Alarms
A01590 (F) Drive: Motor maintenance interval expired
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
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 (power off/on).
- upgrade firmware to later version.
- contact the Hotline.
A01900 (F) PROFIBUS: Configuration telegram error
Reaction: NONE
Acknowledge: NONE
Cause: A PROFIBUS master attempts to establish a connection using an incorrect configuring telegram.
Alarm value (r2124, interpret decimal):
50: Syntax error.
52: Too many data words for input or output. Max. 8 words are permitted.
53: Uneven number of bytes for input or output.
Remedy: Check the bus configuration on the master and slave sides.
A01901 (F) PROFIBUS: Parameterizing telegram error
Reaction: NONE
Acknowledge: NONE
Cause: A PROFIBUS master attempts to establish a connection using an incorrect parameterizing telegram.
Alarm value (r2124, interpret decimal):
1: Incorrect parameterizing bits.
10: Illegal length of an optional parameterizing block.
11: Illegal ID of an optional parameterizing block.
Remedy: Check the bus configuration:
- bus addresses
- slave configuring
F01910 (N, A) Fieldbus interface setpoint timeout
Reaction: OFF3 (IASC/DCBRAKE, NONE, OFF1, OFF2, STOP2)
Acknowledge: IMMEDIATELY
Cause: The reception of setpoints from the fieldbus interface has been interrupted, because
- the bus connection was interrupted, or
- the communication peer was switched off.
CU230-2P DP:
- the PROFIBUS master was set to the STOP state.
See also: p2040 (Fieldbus interface monitoring time), p2047 (PROFIBUS additional monitoring time)
Remedy: Ensure bus connection has been established and switch on communication peer.
CU230-2P HVAC:
- if required, adapt p2040.
CU230-2P DP:
- set the PROFIBUS master to the RUN state.
- slave redundancy: For operation on a Y link, it must be ensured that "DP alarm mode = DPV1" is set in the slave
parameterization.
