Preface and Precautions
AC10 Series Frequency Inverter Technical Manual 2
DANGER
Please pay attention to all the information about safety in this book.
If you do not follow the warnings, you may cause death or serious injury, so please pay attention. The company will not be responsible for any damage
or equipment damage caused by your company or your company's customers who fail to comply with the contents of this book.
In order to prevent electric shock
Do not perform inspection or wiring work while the power is on. Be sure to turn off the power to all machines before wiring or repair work. Even if the
power is turned off, there is residual voltage in the capacitor inside the drive. To prevent electric shock, at least wait for the time specified on the
warning label on the front panel of the unit. After the indicators are all off, remove the front cover and terminal cover, measure the input supply voltage
and the main circuit DC voltage, and confirm that it is below the safe voltage.
WARNING
For mechanical safety
After the wiring operation and parameter setting are completed, be sure to carry out trial operation to confirm that the machine can operate safely,
otherwise it may cause injury or equipment damage.
Be sure to confirm the setting value of the parameters for the virtual input/output function before the drive is tested.
The virtual input/output function is to make the virtual connection of the input and output terminals inside the drive. Therefore, even if there is no wiring
on the input and output terminals, the operation of the drive may be different from the factory setting. If it is neglected, the accidental operation of the
drive may cause personal accidents.
Before turning on the drive power supply, make sure there are no people around the drive, motor, and machine. Also, check that the cover, coupling,
shaft key, and machine of the drive are properly protected.
Some systems may suddenly move the machine when the main circuit is energized, posing a risk of death or serious injury.
The drive's external terminal control is used. The function of the drive's input and output terminals will be different from the factory settings. Therefore,
the operation of the drive may be different from the factory settings described in the instruction manual. Before the drive is tested, please use the
external terminal control to confirm the input and output signals and internal sequence of the drive.
Prevent electric shock
It is forbidden to modify the drive.
If your company or your company's customers have modified the product, the company will not be responsible.
Non-electrical construction professionals should not perform wiring, installation, maintenance, inspection, component replacement or repair work.
Do not remove the cover of the drive or touch the printed circuit board while the power is on.
Prevent fire
Do not mistake the voltage of the main circuit power supply. Before powering on, please confirm whether the rated voltage of the drive is consistent
with the power supply voltage.
Please follow the local standards and set the bypass protection circuit. Improper wiring may result in fire or personal accident.
NOTE
In order to prevent injuries
Do not carry the drive with the front cover or terminal cover of the drive. In addition, please confirm that the screws are properly tightened before
handling.

Preface and Precautions
3 AC10 Series Frequency Inverter Technical Manual
TIPS
Use a motor that meets the insulation requirements of the PWM drive to prevent short-circuit or short-circuit to ground due to insulation degradation.
When operating the drive or disassembling the printed circuit board, follow the steps specified in the static electricity prevention measures (ESD). If the
operation is incorrect, the internal circuit of the drive may be damaged due to static electricity.
The withstand voltage test cannot be performed on any part of the drive. This device uses a precision instrument and may cause damage to the drive
due to high voltage.
Do not run a machine that has been damaged. If the machine is obviously damaged or parts are missing, do not connect or operate, otherwise the
machine damage and other problems will increase.
Do not turn the power on or operate the machine immediately when the fuse blows or the leakage circuit breaker trips. Please check the cable wiring
and the selection of the peripheral machine to find out the cause of the problem. If you are unsure of the cause, please contact us and do not switch
on the power or operate the machine.
When packaging wood materials need to be disinfected or dewormed, be sure to use methods other than fumigation. For example: heat treatment (30
minutes or more at a core temperature of 56 ° C or higher) In addition, please dispose of the material before packaging, rather than treating the whole
after packaging.
When electrical products (single or mechanically mounted) are packaged in fumigation-treated wood, the gases and vapors produced by the packaging
may cause fatal damage to the electronics. In particular, halogen disinfectants (fluorine, chlorine, bromine, iodine, etc.) may cause internal corrosion
of the capacitor, and DOP gas (phthalate) may cause cracking of the resin or the like.

2.7 Types and Characteristics of Control Modes
The drive can select AM-V/F control (initial setting) and AM-open loop vector control.
Asynchronous motor V/F control
It means that when the frequency (F) is variable, the ratio of the control frequency to the voltage (V) remains constant.
This control mode is used for all variable speed control that does not require fast response and precise speed control, as well as the use of multiple
drives with one frequency drive. This method is also used when the motor parameters are not clear or cannot be self-tunned.
Asynchronous motor open loop vector control
The vector can be divided into the excitation current and the torque current by performing vector calculation on the output current of the drive, and
the frequency and voltage are compensated to flow the motor current matched with the load torque to improve the low speed torque. At the same
time, the output frequency compensation (slip compensation) is implemented to make the actual rotation speed of the motor closer to the speed
command value.
This control mode is used for applications requiring high speed control accuracy. High speed response and torque responsiveness, high torque
output at low speeds. Suitable for general high-performance control applications, one drive can only drive one motor.
Note：
For best control, enter the motor parameters correctly and perform motor self-tunning. The F02.0x group is the basic parameter group of the motor.
In the open loop control, the drive can only drive one motor; and the drive capacity and motor capacity can not be too different, the drive can be two
or smaller than the motor's power level, otherwise the control performance may be degraded. , or the drive system is not working properly.

● While transporting the drive, please hold the firm case. If only hold the pre-cover, there is danger of drive main body falling,
injury or drive damage.
Cautions in use motor
● Different motor has different max allowable running speed. Motor can not run over the max allowable running speed.
● While drive is running at low speed, the motor auto-cool effect is seriously worse. If motor runs at low speed for long time, it
will be damaged for overheat. If needed, please use special motor for drive.
● While constant speed machinery runs at inconstant speed, there maybe sympathetic vibration. Please install vibration-proof
rubber under motor rack or use jumping frequency control function.
● While using frequency drive or working frequency power supply to drive, the torque characteristic are different. Please do
confirm the torque characteristic of the equipment connected.
● The rated current of diving motor is higher than that of standard motor, please confirm it and choose the right drive.
● While the wire between motor and drive is long, the max torque of the motor will reduce for voltage drop. So please use thick
cable while the distance between the motor and the drive is long.

3.5 Standard Wiring
This chapter explains the regulations that users have to obey to ensure safe use, best performance and reliable running.
Safety precaution
● Must earth reliably while drive is running. Otherwise there is danger of casualty and unstable drive performance.
● To ensure safe running, only trained professional person can do installation and wiring job.
● No operation under power connected state. Otherwise there is danger of electric shock even death.
● Before operation, please cut all related equipments power, ensure that the main circuit DC current has dropped to
safe range. And please operate after 5 mins.
● Control cable, power cable and motor cable must be separated. They can not be in the same cable trough or cable
rack.
● This equipment can only be used as the maker states. Please consult Veichi while using in special case.
● No insulation test for the drive or the related cable by HV insulation test equipment.
● If the drive or the peripheral equipment (filer, reactor and etc) needs insulation test, firstly 500V megohmmeter
should be used to test the insulation resistance which should not be lower than 4MΩ.

Note:
1. Please select the appropriate braking resistor according to the site working conditions and the 《Braking Resistor Specification Parameters》.
2. The multi-function input terminals (X1 to X4/PUL) can support NPN transistor signals as inputs.
3. The analogue monitoring output is a dedicated output for indicator meters such as ammeters and voltmeters, and should not be used for control
operations such as feedback control.
4. As there are several pulse types in practice, please see the detailed description for the specific wiring.
5. For 0.4kW to 5.5kW drives, the COM and GND terminals are two-in-one function terminals and are combined externally as GND terminals; for
7.5kW to 22kW drives, both COM and GND terminals are available.
