Uv1
Undervoltage Detection
1
Voltage in the DC bus
fell below the
undervoltage detection
level (P2-03) during run.
·
200 V class: 190 V
·
400 V class: 380 V
1. Input power phase loss
2. Loose wiring terminals of
drive input power
3. Problem with the voltage
from the drive input power
4. The drive main circuit
capacitors are weakened.
5. The contactor or relay on
the soft-charge bypass
circuit is damaged
1. Correct the drive input power
wiring
2. Tighten the terminals
3. Check the voltage
a. Adjust the voltage according
to the drive input power
specifications
b. Check the main circuit
magnetic contactor if there is no
problem with the power supply
4. Turn on and turn off the power
to see if any problem occurs
a. Replace either the entire drive
or the control board if the
problem continues to occur.
Contact the local distributor for
more information.

Input Phase Loss
Drive input power has a
large imbalance of
voltage between
phases or has an open
phase
(Detected when
P7-00=1)
1. Phase loss in the drive
input power
2. Drive input power
terminals has a loose wiring
3. Drive input power
voltage has an excessive
fluctuation
4. The main circuit
capacitors are impaired
1. Check wiring for errors in the
main circuit drive input power
»Correct wiring
2. Make sure the terminals are
tightened correctly
»Apply the tightening torque as
showed in the manual
3. Confirm the voltage from the
drive input power
»Apply possible solutions for
drive input power stabilization
4. Check drive input power. If
drive input power seems normal
