Error Cause Diagnosis/Remedy Reaction
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.
Off2
F0004, SED2
Overtemperature
• Ventilation is
inadequate.
• The fan is inoperative.
• The ambient
temperature is too high.
Check the following:
• The fan must turn when the
SED2 is running.
• The pulse frequency must
be set to a lower value.
• The ambient temperature
could be higher than
specified for the SED2.
Off2
F0005, SED2 I2T
• The SED2 is
overloaded.
• The duty cycle is
outside the tolerance.
• The motor power
(P0307) exceeds the
SED2 power (P0206).
Check the following:
• The load cycle must lie
within the limits specified.
• 2Motor power (P0307)
SED2 power (P0206).
Off2
F0011, Motor
overtemperature
• The motor is overloaded
Make sure that the load duty cycle
(temporary overload) lies within the
limits specified.
