DESCRIPTION POSSIBLE CAUSES
F0021
Undervoltage fault on the intermediate circuit.
•
Wrong voltage supply; check if the
data on the inverter label complies
with the power supply and parameter
PO296.
•
Supply voltage too low, producing
voltage on the DC link below the
minimum value (in P0004):
Ud<200 Vdc in 200-240 Vac (P0296=0).
Ud<360 Vdc in 380-480 Vac (P0296=1).
Ud<500 Vdc in 500-600 Vac (P0296=2).
•
Phase fault in the input.
•
Fault in the pre-charge circuit.
F0022
Overvoltage fault on the intermediate circuit.
•
Wrong voltage supply; check if the
data on the inverter label complies
with the power supply and parameter
P0296.
•
Supply voltage is too high, producing
voltage on the DC link above the
maximum value (in P0004):
Ud>410 Vdc in 200-240 Vac (P0296=0).
Ud>810 Vdc in 380-480 Vac (P0296=1).
Ud>1000 Vdc in 500-600 Vac (P0296=2).
• Load inertia is too high or deceleration
ramp is too fast.
•
P0151 or P0153 setting is too high.
F0031
•
Communication card failure
F0048 Overload fault on the power pack with IGBTs
(3 s in 1.5XL).
•
Inverter output overcurrent (>2xl)
A0050/F0051 Drive over-temperature
• Possible Cooling Fan Failure
A0046/F0072 Motor load to high
•
Possible Pump failure
F0070
Overcurrent or short-circuit on the output, DC link
or braking resistor.
• Short-circuit between two motor
phases.
•
Short-circuit of the rheostatic braking
resistor connecting cables.
•
IGBTs module in short-circuit or
damaged
•
Start with too short acceleration ramp.
•
Start with motor spinning without the
Flying Start function.
