Cause
Possible Solution
7. Speed Search related
parameters are set
incorrectly
8. Power supply phase loss
causes output current
oscillation
» Set a lower value to C6-00
(Carrier Frequency)
6. Check the torque
compensation
» Set a lower value to C3-00
(Torque Compensation Gain)
until the current is decreased
and the motor does not stall.
7. Adjust parameters related to
Speed Search
» Adjust b3-03
8. Check the power supply for
phase loss

Overtorque
Detection 1
The current has
exceeded the torque
level set to P6-01 for
longer than the time
set to P6-02
1. Incorrect parameter
settings
2. Malfunction on the
machinery side
1. Reset P6-01 and P6-02
2. Check machinery and load
status

Undertorque
Detection 1
The current has
dropped below the
torque detection
level set to P6-01 for
longer than the time
set to P6-02
1. Incorrect parameter
settings
2.Malfunction on the
machinery side
1. Reset P6-01 and P6-02
2. Ensure there is no problem on

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
