(3) Restarting methods
- Restart with an active matching frequency
The inverter starts the output with the frequency specified for the start frequency selection (b030),
searches for the point where the frequency and voltage are balanced while keeping the current at
the restart current level (b028), and then restarts the motor.
If the inverter trips when it restarts the motor in this way, reduce the setting of "b028".
- After the inverter output has been shut off, the digital operator continues to display until
the inverter restarts the motor operation.
