Thank you for using HV950 series inverter made by HNC
HV950 series satisfies high performance requirements by using a unique control
method to achieve high torque, high accuracy and wide speed-adjusting range. Its
anti-tripping function and capabilities of adapting severe power network, temperature,
humidity, and dusty environment exceeds those of similar products made by other
companies, which improves the products reliability noticeably.
HV950considers customers’ needs and combines general purpose function and
industrial-oriented function. It features PI control, simple PLC, flexible I/O terminals
and pulse frequency setting. You can select whether to save the parameters upon
power off or stop, main and auxiliary frequency setting, etc. It is an integral,
cost-effective and highly reliable solution for manufacture in the related fields.
HV950 series can satisfy the customers’ requirements on low noise and EMI by
using optimized PWM technology and EMC design.
This manual provides information on installation, wiring, parameters setting,
trouble-shooting, and routine maintenance. In order to ensure the correct installation
and operation of the inverter, please read this manual carefully before using and keep
it in a safe place.

2. Inspection
Don’t install or use any inverter that is damaged or have fault parts otherwise
may cause injury.
Check the following items when unpacking the inverter.
1. Ensure there is operation manual and warranty cards in the packing box.
2. Inspect the entire exterior of inverter to ensure there are no scratches or
other damaged caused by transportation.
3. Check the nameplate and ensure it is what you ordered.
4. Ensure the optional parts are what you need if you have ordered any
optional parts.
Please contact the local agent if there is any damage in the inverter or the
optional parts.

HV950 series inverter (3phase product) is equipped with braking unit. If there
is a need for energy-consuming braking, please select a braking resistor in
Table2-3
The above Table 2-3 is a guide reference only, users can choose different braking
resistance and power according to each application.However, please be remembered
that the braking resistance shouldn’t be less than the above recommended value, but
the power is allowed to be exceed than the recommend numbers.Users need to select
the right braking resistors according to each application case,there are quite a few
aspects which will determine your choice of the resistors, such as the power of the
motor, system inertia,deceleration time, the energy of the load etc.The greater the
system inertia is, the shorter the required deceleration time is required,then the
braking frequency will be increased, which means you need to choose a bigger power
braking resistor with a lower braking resistance.
Note: the 220V single phase inverter has no brake unit buit in.

4. Installation and Wiring
4.1 Installation
1. Mount the inverter vertically indoors, with good ventilative conditions.
2.Ambient temperature should be within the range of-10℃~ 40℃. If the
temperature is higher than 40 ℃, the inverter should be derated and forced heat
dissipation is required.
3. Humidity should be lower than 90％，non-condensing;
4. Mount in the location free of direct sunlight, dust, metal powder, corrosive
gas or combustible gas；
5.Mount in the location where vibration is less than5.9m/s2（0.6g）；
6. Dust-free, floating fiber and metal particles；
7. Install flat solid, no vibration；
8. Away from electromagnetic interference source.

The PLC terminal can sink or source current. Wire connections X1~X5is flexible
and the typical wiring is shown below：
①Connection method 1
It is default to use the inverter’s internal power source 24V, i.e. PLC connected
with P24.
If you want to use external power supply, make sure to remove the wire between
PLC and P24.

16
Figure 4-3 External power supply wiring diagram
②Connection Method 2
Inverter’s internal +24V power supply is used and the external controller
uses PNP transistors whose common emitters are connected, as shown in
Figure 3-14.
