Description
Possible Causes
A Phase Loss at the inverter input.
The input voltage imbalance is > 5 %.
The input voltage is too low and the DC link voltage
dropped below the minimum permitted value
(monitor the P0004 parameter value):
Ud < 223 V - 200 / 240 V three-phase input
voltage.
Ud < 170 V - 200 / 240 V single-phase input
voltage (CFW700XXXXS2 or CFW700XXXXB2
models)
(P0296 = 0).
Ud < 385 V - 380 V input voltage (P0296 = 1).
Ud < 405 V - 400 / 415 V input voltage
(P0296 = 2).
Ud < 446 V - 440 / 460 V input voltage
(P0296 = 3).
Ud < 487 V - 480 V input voltage
(P0296 = 4).
Ud < 530 V - input voltage 500 / 525 V
(P0296 = 5).
Ud < 580 V - input voltage 550 / 575 V
(P0296 = 6).
Ud < 605 V - input voltage 600 V (P0296 = 7).
Phase loss at the inverter input.
Pre-charge circuit failure.
Parameter P0296 was set to a value higher than
the power supply rated voltage.
Too high input voltage, resulting in a DC link voltage
higher than the maximum permitted value:
Ud > 400 V - 220 / 230 V models (P0296 = 0).
Ud > 800 V - 380 / 480 V models
(P0296 = 1, 2, 3, or 4).
Ud > 1000 V - 500 / 600 V models
(P0296 = 5, 6 or 7).
The inertia of the driven-load is too high or the
deceleration time is too short.
The parameter P0151, P0153 or P0185 setting
is too high.
The settings of P0156, P0157 and P0158 are too
low for the used motor.
There is excessive load at the motor shaft.
The inverter output current is too high.
The inverter output current is too high.
