Working state of VFD
The working state of the ST310 series frequency converter is divided into shutdown state, running state, and
motor parameter self-tuning state.
Shutdown state: After the frequency converter is powered on and initialized if there is no operation command input,
or after the stop command is executed during operation, the 3-phase U/V/W terminal of the converter has no output,
and the running status indicator light of the operation panel, RUN, is not on.
Running state: After the frequency converter receives the running command, the 3phase U/V/W terminal of the
frequency converter starts to have output, and the operation status indicator light on the operation panel is always on.
Motor parameter self-tuning state: Set motor parameters to P02.00-P02.05, and select P02.07 as 2 static self-setting or
3 rotary self-setting according to the current state of the motor. After selecting Confirm, the panel will display Tune.
Press Run to enter the self-setting state. After the self-setting, it will return to the shutdown state.
