HD2 Series Inverter

Safety Precautions

Note:
Select appropriate tools for delivery and installation to ensure a safe and proper running of the inverter and avoid physical injury or death. To ensure physical safety, the installation staff should take mechanical protective measures like wearing exposure shoes and working uniforms.
Ensure to avoid physical shock or vibration during delivery and installation. Do not carry the inverter by its front cover only as the cover may fall off. Installation site should be away from children and other public places. The inverter should be used in proper environment (see section 4.2.1 Installation environment for
details). Prevent the screws, cables, and other conductive parts from falling into the inverter, As leakage current of the inverter during running may exceed 3.5mA, ground properly and ensure
the grounding resistance is less than 10. The conductivity of PE grounding conductor is the same with that of the phase conductor (with the same cross- sectional area). For models higher than 30 kW, the cross-sectional area of the PE grounding conductor can be slightly less than the recommended area. R, S and T are the power input terminals, and U, V and W are output motor terminals. Connect the input power cables and motor cables properly; otherwise, damage to the inverter may occur.
1.4.2 Commissioning and running
Disconnect all power sources applied to the inverter before terminal wiring and wait for at least the time designated on the inverter after disconnecting the power sources.
High voltage presents inside the inverter during running. Do not carry out any operation on the inverter during running except for keypad setting. For products at voltage levels of 6, the control terminals form extra-low voltage circuits. Therefore, you need to prevent the control terminals from connecting to accessible terminals of other devices.
The inverter may start up by itself when P01.21 (restart after power down) is set to 1. Do not get close to the inverter and motor.
The inverter cannot be used as “Emergency-stop device”. The inverter cannot act as an emergency brake for the motor; it is a must to install
mechanical brake device. During driving permanent magnet synchronous motor, besides above-mentioned
items, the following work must be done before installation and maintenance. 1. Disconnect all the input power sources including main power and control
power. 2. Ensure the permanent-magnet synchronous motor has been stopped, and the
voltage on output end of the inverter is lower than 36V. 3. After the permanent-magnet synchronous motor is stopped, wait for at least
the time designated on the inverter, and ensure the voltage between “+” and “-” is lower than 36V.

Safety Precautions

4. During operation, it is a must to ensure the permanent-magnet synchronous motor cannot run again by the action of external load; it is recommended to install effective external brake device or disconnect the direct electrical connection between permanent-magnet synchronous motor and the inverter.

Note:
Do not switch on or switch off input power sources of the inverter frequently. For inverters that have been stored for a long time, set the capacitance, and carry out inspection
and pilot run on the inverter before use. Close the front cover before running; otherwise, electric shock may occur.
1.4.3 Maintenance and component replacement
Only well-trained and qualified professionals are allowed to perform maintenance, inspection, and component replacement on the inverter.
Disconnect all the power sources applied to the inverter before terminal wiring and wait for at least the time designated on the inverter after disconnecting the power sources.
Take measures to prevent screws, cables, and other conductive matters from falling into the inverter during maintenance and component replacement.

Note:
Use proper torque to tighten the screws. Keep the inverter and its parts and components away from combustible materials during
maintenance and component replacement. Do not carry out insulation voltage- endurance test on the inverter or measure the control circuits
of the inverter with megameter. Take proper anti-static measures on the inverter and its internal parts during maintenance and
component replacement.
1.4.4 What to do after scrapping

The heavy metals inside the inverter should be treated as industrial effluent.
When the life cycle ends, the product should enter the recycling system. Dispose of it separately at an appropriate collection point instead of placing it in the normal waste stream.

Product Overview

3 Product Overview
3.1 What this chapter contains
This chapter mainly introduces the operation principles, product features, layouts, nameplates, and model instructions.
3.2 Basic principle
HD2-UL series inverter is used to control asynchronous AC induction motor and permanent-magnet synchronous motor. The figure below shows the main circuit diagram of the inverter. The rectifier converts 3PH AC voltage into DC voltage, and the capacitor bank of the intermediate circuit stabilizes the DC voltage. The inverter converts DC voltage into the AC voltage used by AC motor. When the circuit voltage exceeds the maximum limit value, external brake resistor will be connected to intermediate DC circuit to consume the feedback energy.

Environment Installation site
Ambient temperature

Condition
Indoor
-10­+50°C When the ambient temperature exceeds 40°C, derate 1% for every
additional 1°C. For details about derating, see section B.2.2 Derating. It is not recommended to use the inverter when the ambient temperature
is above 50°C. To improve reliability, do not use the inverter in cases where the
temperature changes rapidly. When the inverter is used in a closed space such as control cabinet, use
cooling fan or air conditioner to prevent internal temperature from exceeding the temperature required. When the temperature is too low, if restart an inverter which has been idled for a long time, it is required to install external heating device before use to eliminate the freeze inside the inverter, failing to do so may cause damage to the inverter.

can protect neighboring equipment from being damaged. 4.5.2 Protecting the motor and motor cable in short circuit

If the motor cable is selected based on rated inverter current, the inverter will be able to protect the motor cable and motor during short circuit without other protective devices.
If the inverter is connected to multiple motors, it is a must to use a separated thermal overload switch or breaker to protect the cable and motor, which may require the fuse to cut off the short circuit current.
4.5.3 Protecting the motor and preventing thermal overload

According to the requirements, the motor must be protected to prevent thermal overload. Once overload is detected, you must cut off the current. The inverter is equipped with motor thermal overload protection function, which will block output and cut off the current (if necessary) to protect the motor.
4.5.4 Bypass connection

In some critical occasions, industrial frequency conversion circuit is necessary to ensure proper operation of the system when inverter fault occurs.
In some special cases, such as only soft startup is needed, it will convert to power-frequency operation directly after soft startup, corresponding bypass link is also needed.
Do not connect any power source to inverter output terminals U, V and W. The voltage applied to motor cable may cause permanent damage to the inverter.

If frequent switchover is needed, you can use the switch which carries mechanical interlock or a contactor to ensure motor terminals will not be connected to input power cables and inverter output ends simultaneously.

5.5.3 Vector control

Asynchronous motors are featured with high order, non-linear, strong coupling, and multi-variables, which makes it very difficult to control asynchronous motors during actual application. The vector control theory aims to solve this problem through measuring and controlling the stator current vector of asynchronous motor, and decomposing the stator current vector into exciting current (current component which generates internal magnet field) and torque current (current component which generates torque) based on field orientation principle, and then controlling the amplitude value and phase position of these two components (namely, control the stator current vector of motor) to realize decoupling control of exciting current and torque current, thus achieving high-performance speed regulation of asynchronous motor.

The HD2-UL series inverter carries built-in speed sensor-less vector control algorithm, which can be used to drive the asynchronous motor and permanent- magnet synchronous motor simultaneously. As the core algorithm of vector control is based on accurate motor parameter model, the accuracy of motor parameters will impact the control performance of vector control. It is recommended to input accurate

HD2-UL inverter also carries built-in SVPWM control function. SVPWM mode can be used in cases where mediocre control precision is enough. In cases where an inverter needs to drive multiple motors, it is also recommended to adopt SVPWM control mode.
HD2-UL inverter provides multiple kinds of V/F curve modes to meet different field needs. You can select corresponding V/F curve or set the V/F curve as needed.
Suggestions:
1. For the load featuring constant moment. e.g: conveyor belt which runs in straight line, as the moment should be constant during the whole running process, it is recommended to adopt straighttype V/F curve.
2. For the load featuring decreasing moment. e.g: fan and water pump, as the relation between its actual torque and speed is squared or cubed, it is recommended to adopt the V/F curve corresponds to power of 1.3, 1.7 or 2.0.

HD2-UL inverter also provides multi-point V/F curve. You can alter the V/F curve outputted by inverter through setting the voltage and frequency of the three points in the middle. The whole curve consists of five points starting from (0Hz, 0V) and ending in (fundamental motor frequency, rated motor voltage).

HD2-UL inverter provides dedicated function codes for SVPWM control mode. You can improve the

performance of SVPWM through settings.

1. Torque boost

Torque boost function can effectively compensate for the low-speed torque performance during SVPWM control. Automatic torque boost has been set by default to enable the inverter to adjust the torque boost value based on actual load conditions.

Note:

(1) Torque boost is effective only under torque boost cut-off frequency.

(2) If the torque boost is too large, low-frequency vibration or overcurrent may occur to the motor, if such situation occurs, lower the torque boost value.

2. Energy-saving run
During actual running, the inverter can search for the maximum efficiency point to keep running in the most efficient state to save energy.
Note:
(1) This function is generally used in light load or no-load cases.
(2) This function does for fit in cases where load transient is required.
3. V/F slip compensation gain
SVPWM control belongs to open-loop mode, which will cause motor speed to fluctuate when motor load transients. In cases where strict speed requirement is needed, you can set the slip compensation gain to compensate for the speed variation caused by load fluctuation through internal output adjustment of inverter.
The set range of slip compensation gain is 0­200%, in which 100% corresponds to rated slip frequency.
Note: Rated slip frequency= (Rated synchronous speed of motor – Rated speed of motor) × Number of motor pole pairs/60
4. Oscillation control
Motor oscillation often occurs in SVPWM control in large-power drive applications. To solve this problem, the HD2-UL series inverter sets two function codes to control the oscillation factor, and you can set the corresponding function code based on the occurrence frequency of oscillation.
Note: The larger the set value, the better the control effect, however, if the set value is too large, it may easily lead to too large inverter output current.
5. Asynchonous motor IF control
Generally, the IF control mode is valid for asynchronous motors. It can be used for a synchronous motor only when the frequency of the synchronous motor is extremely low. Therefore, the IF control described in this manual is only involved with asynchonrous motors. IF control is implemented by performing closed-loop control on the total output current of the inverter. The output voltage adapts to the current reference, and open-loop control is separately performed over the frequency of the voltage and current.
