Table 10- 8 The most important alarms and faults
Number Cause
Remedy
F01018
Power-up aborted more than once 1.
Switch the module off and on again.
2.
After this fault has been output, the module is booted with the factory
settings.
3.
Recommission the converter.
A01028
Configuration error
Explanation: Parameterization on the memory card has been created with
a different type of module (order number, MLFB).
Check the module parameters and recommission if necessary.
F01033
Unit switchover: Reference param-
eter value invalid
Set the value of the reference parameter not equal to 0.0 (p0304, p0305,
p0310, p0596, p2000, p2001, p2002, p2003, r2004).
F01034
Unit switchover: Calculation of the
parameter values after reference
value change unsuccessful
Select the value of the reference parameter so that the parameters in-
volved can be calculated in the per unit notation (p0304, p0305, p0310,
p0596, p2000, p2001, p2002, p2003, r2004).
F01122
Frequency at the probe input too
high
Reduce the frequency of the pulses at the probe input.
A01590
Motor maintenance interval lapsed Carry out maintenance and reset the maintenance interval (p0651).
A01900
PROFIBUS: Configuration tele-
gram faulty
Explanation: A PROFIBUS master is attempting to establish a connection
with a faulty configuration telegram.
Check the bus configuration on the master and slave side.
A01910
F01910
Setpoint timeout
The alarm is generated when p2040
≠
0 ms and one of the following
causes is present:
•
The bus connection is interrupted
•
The MODBUS master is switched off
•
Communications error (CRC, parity bit, logical error)
•
An excessively low value for the fieldbus monitoring time (p2040)
A01920
PROFIBUS: Cyclic connection
interrupt
Explanation: The cyclic connection to PROFIBUS master is interrupted.
Establish the PROFIBUS connection and activate the PROFIBUS master
with cyclic operation.
A03520
Temperature sensor fault
Check that the sensor is connected correctly.
A05000
A05001
A05002
A05004
A05006
Power Module overtemperature
Check the following:
- Is the ambient temperature within the defined limit values?
- Are the load conditions and duty cycle configured accordingly?
- Has the cooling failed?
F06310
Supply voltage (p0210) incorrectly
parameterized
Check the parameterized supply voltage and if required change (p0210).
Check the line voltage.
F07011
Motor overtemperature
Reduce the motor load.
Check ambient temperature.
Check the wiring and connection of the sensor.
A07012
I2t Motor Module overtemperature Check and if necessary reduce the motor load.
Check the motor's ambient temperature.
Check thermal time constant p0611.
Check overtemperature fault threshold p0605.
A07015
Motor temperature sensor alarm
Check that the sensor is connected correctly.
Check the parameter assignment (p0601).
