Fault Descriptions
Brake resistor fault
Y-connection/∆-connectio
n switch error
When Pr.07-13 is not set
to 0 and momentary
power off or power cut, it
will display dEb during
accel./decel. stop.
It will be displayed when
slip exceeds Pr.05-26
setting and time exceeds
Pr.05-27 setting.
Electric valve switch error when executing Soft Start.
(This warning is for frame E and higher frame of AC drives)
Do not disconnect RST when drive is still operating.
Hardware error of PG Card
Check if PG Card is insert to the right slot and parameter settings for encoder are
accurate.
Rotaing direction is different from the commanding direction deteced by the
sensorless.
Solution
Verify if the parameter setting of the motor drive is correct
Increase the estimator's bandwidth and verify if parameters relating to the sensorless
are correct.
Overspeed rotation detected by the sensorless
Solution
Verify if the parameter setting of the motor drive is correct
Increase the estimator's bandwidth and verify if parameters relating to the sensorless
are correct.
Verify if the gains of the speed circuit is reasonable.
Big difference between the rotating speed and the command deteced by the
sensorless
Solution
Verify if the parameter setting of the motor drive is correct
Increase the estimator's bandwidth and verify if parameters relating to the sensorless
are correct.
Verify if the gains of the speed circuit is reasonable.
Emergency stop for external safety

Corrective Actions
If the fault code is still displayed on the keypad after
pressing "RESET" key, please return to the factory.
1. Check the wiring of the Y-connection/∆-connection
2. Check the parameters settings
1. Set Pr.07-13 to 0
2. Check if input power is stable
1. Check if motor parameter is correct (please
decrease the load if overload
2. Check the settings of Pr.05-26 and Pr.05-27
