Number
Cause
Solution
A07920
F07923
Torque/speed too low The torque deviates from the torque/speed envelope
curve.
1.
Check the connection between the motor and load.
2. Adjust the settings according to the load.
A07921
F07924
Torque/speed too high
A07922 Torque/speed out of
tolerance
A07927 DC braking active The alarm disappears after DC braking.
A07980 Rotating measurement
activated
The alarm disappears after optimization of the speed
controller.
A07981 Rotating measurement: No
enable signals
1. Acknowledge pending faults.
2.
Create enable signals which are missing.
A07991 Motor data identification
activated
The alarm disappears after motor data identification.
A30049 Internal fan defective  Check the internal fan and replace it, if necessary.
A30502 DC link overvoltage
1. Check the device supply voltage (p0210).
2. Check the dimensions of the line reactor.
A30920 Temperature sensor fault  Check that the sensor is correctly connected.
Faults
Number
Cause
Solution
F01000 Software fault in CU  Replace the CU.
F01001 FloatingPoint exception  Switch the CU off and on again.
F01015 Software fault in CU
1. Update the firmware
2.
Contact Technical Support.
3. Replace the CU.
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 drive.
F01033 Switching over units:
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 Switching over units:
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
representation (p0304, p0305, p0310, p0596, p2000,
p2001, p2002, p2003, r2004).
F01040 Parameters must be saved
1. Save the parameters (p0971).
2. Switch the CU off and on again.
F01044 Fault loading the data from
the memory card
 Replace the memory card of the CU.
F01105 Insufficient memory  Reduce the number of data records.
F01122 Frequency at the probe
input too high
 Reduce the frequency of the pulses at the measuring
input.
F01205 Time slice overflow  Contact Technical Support.
F01250 CU hardware fault  Replace the CU.
F01512 No scaling An attempt has been made to establish a conversion
factor for scaling which is not present.
 Apply scaling or check the transfer value.
