Number
Cause
Remedy
p0970 = 5 Reset Start Safety Parameter.
The converter sets p0970 = 5 if it has reset the parameters.
Then reset the converter to the factory setting again.
A01666 Static 1 signal atF-DI for safe
acknowledgment
F-DI to a logical 0 signal.
A01698 Commissioning mode active for
safety functions
This message is withdrawn after the Safety commissioning has ended.
A01699 Shutdown path test required After the next time that the "STO" function is deselected, the message is
withdrawn and the monitoring time is reset.
F30600
STOP A Triggered
STO Select and then deselect again.
Table 11- 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
parameter 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
involved 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
telegram 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.
