Siemens SINAMICS V10 - Comprehensive Fault List

Acknowledging alarm(s)
In the event of an alarm, no key or button is required for acknowledging or clearing the alarm
code. After the alarm cause is removed, the alarm code will automatically disappear.
Note
When multi-alarms occur, the alarm code is always displayed as x.Axxx. For example:
"1.A501" = The first alarm code A0501
"2.A503" = The second alarm code A0503
To view the alarm history, go to r2110.
Fault list
Fault Possible Causes Diagnose & Remedy
F0001
Overcurrent
● Short-circuit at the output
● Ground fault
● Excessively large motor (the motor
power rating P0307 is greater than the
inverter power r0206)
● Defective final stage (end stage)
● Are the cable lengths within the limit values?
● Does the motor cable or motor have either a
short-circuit or ground fault?
● Do the motor parameters correspond to those of
the motor being used?
● Is the motor overloaded or stalled (locked rotor)?
● Increase the accelerating time.
● Reduce the gain (P2280)
● Use a motor with a lower power rating
● Is the stator resistance value (P0350) correct ?
F0002
Overvoltage
● DC link voltage (r0026) higher than the
overvoltage threshold (refer to
parameter r0026)
● Ground fault
● Is the line supply voltage within the permissible
range?
● Has the DC current DC link monitoring been
enabled (P1240) and correctly parameterized?
● Extend the deceleration ramp (ramp-down time
P1121, P1135)
● Remove the ground fault
● Is the required braking power within the
permissible limits?
F0003
Undervoltage
● Line voltage failed
● Shock stressing outside the permissible
limits
● Is the line supply voltage within the permissible
range?
● is the line supply voltage stable with respect to
sporadic failures and voltage dips (brown-outs)?
F0004
Inverter overtemp.
● Inadequate cooling
● Ambient temperature is too high
● Is the pulse frequency P1800 set to the factory
setting? If required, reset P1800.
● Does the ambient temperature lie within the
permissible limits?
● Reduce the load and / or ensure adequate
cooling
● Does the fan rotate if the inverter is operational?
