Fault Name
Cause
Possible Solution
below the rated speed with
a high load
4. Incorrect setting in P1-00
(Motor Protection Function
Selection) when running a
special motor
5. The voltage determined
by the V/F is too high
6. d2-00 (Motor Rated
Current ) setting incorrect
7. The base frequency is set
too low
8. Use one drive to run
multiple motors
9. The electrical thermal
protection characteristics
do not match the motor
overload characteristics.
10. The electrical thermal
relay operates at the wrong
level
11. Motor overheated by
overexcitation operations
12. Speed Search related
parameters are set
incorrectly
13. Power supply phase loss
causes output current
oscillation.
parameter settings
3. »Reduce the load
» Increase the speed
» Either increase the motor
capacity or use a special-purpose
motor if the motor needs to
operate at low speeds
4. Set P1-00 to 2.
5. Adjust d1-02 to d1-11 settings
(V/F Characteristics)
Note: If d1-02 to d1-11 settings
are too low, load tolerance at low
speeds will be reduced
6.Confirm the motor rated
current
» Set d2-00 (Motor Rated
Current ) according to the motor
nameplate
7. Confirm the rated frequency
showed on the motor nameplate
»Set d1-04 (Base Frequency)
according to the motor
nameplate
8. Set P1-00 (Motor Protection
Function Selection) to 0
(Disabled) and install a thermal
relay to each motor
9. Confirm characteristics of the
motor
»Set P1-00 (Motor Protection
Function Selection) correctly
»Install an external thermal relay
10. Overexcitation increases the
motor loss
11. Adjust parameters related to
Speed Search
»Adjust the b3-01 (Speed Search
Operation Current ) setting
12. Check the power supply for
phase loss
