Probable cause and remedy
Fault name and meaning
%U
Overvoltage (OV)
The main circuit DC voltage
has reached the overvoltage
detection level (410 V DC for
200-V Inverters,
820 V DC for 400-V Inverters)
•
There is excessive regenerative energy with no braking
resistor or Braking Resistor Unit connected.
→
Connect the Braking Resistor Unit or a braking resistor.
→
Increase the deceleration time.
•
The regenerative energy has not been processed though a
braking resistor or Braking Resistor Unit.
→
Set n092 for stall prevention during deceleration to 1
(disable)
•
The braking resistor or Braking Resistor Unit is not wired prop-
erly.
→
Check and correct the wiring.
•
The power supply voltage is too high.
→
Decrease the voltage so it will be within specifications.
•
There is excessive regenerative energy due to overshooting
at the time of acceleration.
→
Suppress the overshooting as much as possible.
•
The braking transistor is damaged.
→
Change the Inverter.
uU1
Main circuit undervoltage
(UV1)
The main circuit DC voltage
has reached the undervoltage
detection level (200 V DC for
the 3G3MV-A2
j
, 160 V DC
for the 3G3MV-AB
j
, and 400
V DC for the 3G3MV-A4
j
).
•
Power supply to the Inverter has phase loss, power input
terminal screws are loose, or the power cable is discon-
nected.
→
Check the above and take necessary countermeasures.
•
Incorrect power supply voltage
→
Make sure that the power supply voltage is within
specifications.
•
Momentary power interruption has occurred.
→
Use the momentary power interruption compensation
(Set n081 so that the Inverter restarts after power is
restored)
→
Improve the power supply.
•
The internal circuitry of the Inverter is damaged.
→
Change the Inverter.
uU2
Control power supply
undervoltage (UV2)
The control power supply
voltage has reached the
undervoltage detection level.
•
Internal circuit fault.
→
Turn the Inverter OFF and ON.
→
Change the Inverter if the same fault occurs again.
