Number / Fault Cause Counter-measure
F081
OptBrdHeartbeat-
Counter
Heartbeat-counter of the optional board is no
longer being processed
Fault value r949:
0: TB/CB heatbeat-counter
1: SCB heartbeat-counter
2: Additional CB heartbeat-counter
- Acknowledge the fault (whereby automatic
reset is carried out)
- If the fault re-occurs, replace the board
concerned (see fault value)
- Replace ADB
- Check the connection between the subrack
and the optional boards (LBA) and replace, if
necessary
F082
TB/CB telegram failure
No new process data have been received by
the TB or the CB within the telegram failure
time.
Fault value r949:
1 = TB/CB
2 = additional CB
- Check the connection to TB/CB
- Check P722 (CB/TB TlgOFF)
- Replace CB or TB
F085
Add. CB initialization
fault
A fault has occurred during initialization of the
CB board.
Fault value r949:
1: Board code incorrect
2: TB/CB board not compatible
3: CB board not compatible
5: Error in configuration data
6: Initialization timeout
7: TB/CB board double
10: Channel error
Check the T300 / CB board for correct
contacting and check the CB initialization
parameters:
- P918.02 CB Bus Address,
- P711.02 to P721.02 CB Parameters 1 to 11
F087
SIMOLINK initialization
fault
A fault has occurred during initialization of the
SLB board.
- Replace CU (-A10), or replace the unit
(Compact PLUS type)
- Replace SLB
F090
Mld Param.
An error occurred when attempting to change
a parameter from the standstill measurement
or the rotating measurement (Mot ID).
Power down and power up again. If it
reoccurs, replace CU (-A10), or replace the
unit (Compact PLUS type)
F091
Mld Time
The rotating measurement takes longer than
programmed in a measured status. The
relevant measuring interval is encrypted in
parameter r949. Possible causes:
Load torque too high
Load torque not uniform
Ramp-function generator disabled
Eliminate the cause and re-start the
measurement (power up the converter again).
If it re-occurs, replace CU (-A10), or replace
the unit (Compact PLUS type).
F095
Mld n(set)
Due to entries for
- Permissible phase sequence
- Maximum frequency,
- Minimum speed,
- Changeover frequency between V and I
model,
- Start of field-weakening frequency,
- Frequency suppression bandwidth
it was not possible to determine a permissible
frequency range for the rotating measurement.
There must be a 10 % frequency range which
lies above 1.1 times the changeover frequency
and below 0.9 times the start of field-
weakening frequency.
Possible counter-measures
- Permit both phase sequences
- Increase maximum frequency
- Reduce minimum speed,
- Reduce changeover frequency between the
V and I model.
- Reduce or remove the frequency
suppression bandwidth.
