Error Cause Diagnosis/Remedy Reaction
F0001,
Overcurrent
• Motor power (P0307) is
greater than SED2
power (P0206).
• Motor lead short circuit.
• Earth faults.
Check the following:
• Motor power (P0307) ≤SED2 power
(P0206).
• Cable length limits must not be
exceeded.
• Motor cable and motor must not
have short circuits or earth faults.
• Motor parameters must match the
motor in use.
• Value of stator resistance (P0350)
must be correct.
• The motor must not be obstructed or
overloaded.
• Increase ramp-up time.
• Reduce boost level.
Off2
F0002,
Overvoltage
• DC link voltage (r0026)
exceeds trip level.
• Overvoltage can be
caused either by too
high main supply
voltage or if motor is in
regenerative mode.
• Regenerative mode can
be caused by fast ramp
downs or if the motor is
driven from an active
load.
Check the following:
• The supply voltage must lie within
the limits indicated on the rating
plate.
• The DC link voltage controller must
be enabled (P1240) and
parameterized correctly.
• The ramp-down time (P1121) must
match the inertia of load.
• The required braking power must lie
within the specified limits.
NOTE: Higher inertia requires long ramp-
down times; otherwise, apply braking resistor.
Off2
F0003,
Undervoltage
• Mains supply failed.
• Shock load outside the
specified limits.
Check the following:
• The supply voltage must lie within
the limits indicated on the rating
plate.
• The supply voltage must not be
susceptible to temporary failures or
voltage reductions outside tolerance.
