Remedy
F01000
Internal software error
Replace the inverter.
F01001
FloatingPoint exception
Switch off the inverter and switch on again
F01015
Internal software error
Upgrade firmware or contact technical support.
F01018
Power-up aborted more than
once
1. Switch off the inverter power supply and switch it on again.

3. Recommission the inverter.
A01028
Configuration error
Explanation: The parameter assignments on the memory card were made
with a different type of module (article no.).
Check the module parameters and recommission if necessary.
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 ref‐
erence value change unsuccess‐
ful
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).
F01040
Parameters must be saved
Backup parameter (p0971).
Switch off the inverter and switch on again.
F01044

Activate message for a memory card that is not inserted (Page 332)
F01105
CU: Insufficient memory
Reduce number of data sets.
F01122
Frequency at the probe input too
high
Reduce the frequency of the pulses at the probe input.
F01205
CU: Time slice overflow
Contact technical support.
F01250
CU hardware fault
Replace the inverter.
F01512
An attempt has been made to es‐
tablish a conversion factor for
scaling which does not exist
Create scaling or check transfer value.

Motor maintenance interval
elapsed
Carry out the maintenance.
F01600
STOP A initiated
Select STO and then deselect again.
F01625
Sign-of-life error in the Safety da‐
ta
● Check the electrical cabinet design and cable routing for EMC compliance.
● Check whether an impermissible voltage is connected at one of the digital
outputs.
● Check whether a digital output is loaded with an impermissible current.
● Check whether additional faults exist and perform diagnostics if applicable.
● Select STO safety function and then deselect again.
● Switch off the inverter power supply and switch it on again.
