The drive does not work
when you press the run
key and the run
indicator is off.
The coast-to-stop function terminal
is enabled.
Check the coast-to-stop
terminal
The drive running inhibition terminal
is enabled.
Check the drive running
inhibition terminal
The external stop function terminal
is enabled.
Check the external stop
function terminal
Under the three-wire control mode,
the three-wire control function
terminal is not closed.
Set and close the
three-wire control
terminal
The virtual terminal function of the
host device is set improperly.
Cancel the virtual
terminal function of the
host device or set the
function properly, or
modify the P09.16 setting
The positive/negative logic of the
input terminal is set improperly.
Check the P09.12 and
P09.13 settings.
When the drive is
powered on, it
reports Uv
immediately.
The thyristor or the
contactor is
disconnected and the
drive load is large.
Since the thyristor or the contactor
is not closed, when the drive runs
with large load, the DC bus voltage
of the main circuit will drop, and the
drive will display Uv.
Run the drive after the
thyristor or the contactor
is fully closed, or seek for
technical support
