Power supply
Please use the power supply in
accordance with the rated speci-
fication in the usage manual
Non-fuse switch
or
residual current

(output end)
The length of motor wires will
influence the magnitude of the
reflection wave on the motor end.
When the engine wires are longer
than 20m, it is recommended to
install the AC reactor. Please
refer to the appendix.
Used for shortening the decele-
rating time of motor. Please re-
fer to the appendix.
Used for reducing electromagnetic
interference. Please refer to the
appendix.
Used for reducing the radiation
interference, especially in the
places with audio devices, and at
the same time reducing the inter-
ference of input end and output
ends as well. The effective range
is AM wave band-10MHZ.
When the output capacity is over
1000kVA, it is recommended to add
an AC reactor to improve the fun-
ctional factor. The distance
of wires should be within 10m.
Please do not use the electroma-
gnetic contactor as the power
switch of AC drive, since it will
shorten the service life of AC
drive.
The input current may be heavy
when the power is turned on.
Adopt a proper non-fuse switch or
residual current circuit breaker.
Improve power factor and reduce
AC pulse of DC bus.

Note
：
1.There is no PB terminal for 45kW and above;
2. The bias voltage of S1~S6 ports can be selected from the internal power supply (24V
port) of the inverter, or the external power supply (PLC port), and the factory default
24V port and the PLC
port are short-circuited;
3. The S5 port is constrained by the functional parameter F4-04 and can be used as a
high-speed pulse input channel, with a maximum input frequency of 50KHz;
4. The Y4 port is constrained by the functional parameter F5-00, and can be used as a
high-speed pulse output channel with a maximum output frequency of 50KHz; when used as
an open-collector output,
Same specification as Y3 terminal.
