Last modified by Mora Zhou on 2023/12/28 10:44

This is VM series V1.2. S/N on the inverter starts from "X0".

Preface

Thank you for choosing WECON VM Series AC Drive.

This user manual introduces the technical specifications, installation instructions, functions and performance of VM Series AC Drive properly. Please read this user manual carefully before carrying out works such as installation, commissioning, maintenance, etc.

You are specially warned to read and understand safety precaution items of this manual before using this product, and to ensure that relevant electrical installation testers’ professional qualification shall be in line with the provisions of the labor supervision department, and the electrical and environmental conditions for product use shall be in conformity with relevant national standards.

Be sure to verify that the wiring is correct before powering on the product. Before starting the product, it is necessary to debug to ensure correct motor rotating direction.

Safety precautions

■ Warning sign

WECON VM 英文 V01_html_f697a083b5da7fc8.png DANGER: Indicates that failure to comply with the notice will result in severe personal injure or even death.

WECON VM 英文 V01_html_b36792972403c101.png WARNING: Indicates that failure to comply with the notice will result in moderate personal injury, property damage or equipment damage.

WARNING

◎Do not install or operate any AC Drive that is damaged or with missing parts. Failing to follow this rule can result in facility damage or severe injury.

◎When installing or handling the AC Drive, please hold the bottom of the product rather than the case only, to prevent its falling and being damaged.

◎Install the AC Drive on nonflammable material like metal, and keep away from flammable or explosive object, heat source, and similar environment. Otherwise, fire may be caused.

◎When AC Drive is installed inside an electrical cabinet or other kind of enclosure, please install fans or other cooling devices, and keep ventilation well enough to ensure the enclosure temperature below 40℃, or the AC Drive may be damaged due to extreme high temperature.

◎Before wiring, ensure the AC Drive rated input voltage and phases are compatible with the input power source, or fire or personal injury may be caused.

◎Never connect the AC power supply to output terminals U, V and W. Otherwise, the AC Drive will be damaged and the warranty is invalid.

◎Never carry out withstand voltage test to the AC Drive, for example by a megohmmeter. Otherwise, it may cause damage to the AC Drive.

◎The connecting cable of the main circuit terminal should use an insulating sleeve.

◎When the cable length between the AC Drive and the motor exceeds 50 meters, an output reactor is recommended to be used.

◎Do not use a circuit breaker to control the start and stop of the AC Drive. Otherwise, the AC Drive may be damaged.

◎Since the AC Drive makes the motor running speed from low to high in a short time, please confirm that the motor and equipment are in the allowed running range before running.

◎Do not touch due to high temperature of the heat sink and braking resistor.

◎The factory parameters of the AC Drive can meet the requirments of most equipment operation. Under normal circumstances, please do not modify the AC Drive parameters at will. Even if there is some special applications need to change the AC Drive parameters, only necessary parameters could be changed. Otherwise, AC Drive damage may be caused.

◎The PCB board has a CMOS integrated circuit. Do not touch it with your hands, otherwise, static electricity will damage the PCB board.

DANGER

◎Wiring must be completed by qualified professional electricians, otherwise, there may be electric shock or damage to the AC Drive.

◎The power must be disconnected during wiring; otherwise, it may cause electric shock or fire.

◎The grounding terminal should be effectively grounded; otherwise, the outer casing of the AC Drive may be energized.

◎Do not touch the main circuit terminals, otherwise, it may cause electric shock.

◎Terminals for brake resistor are and PB. Do not wire to other terminals, otherwise, fire may be caused.

◎It is only allowed to power on the AC Drive after the wiring is finished and its cover is reinstalled. It is strictly prohibited to remove the cover of AC Drive while power is on. Otherwise, it may cause electric shock.

◎Before programming the AC Drive with fault auto reset or restart option after power off, the mechanical device need to be implemented with safety protection measures first. Otherwise, personal injury will be caused.

◎“ STOP/RESET” key may become invalid as a result of some function setting. It is recommended to install an independent emergency circuit breaker for the AC Drive control system, otherwise, or personal injury may be caused.

◎When the power is on, there may be electricity in the AC Drive’s terminals even if it is in stop mode. Do not touch U, V, W terminals and motor connection terminals, or electrical shock may be caused.

◎Never touch the AC Drive connection terminals when power is on. Otherwise, it may cause an electrical shock.

◎Only qualified electricians can be authorized to do the jobs of maintenance, checking, or parts replacement.

◎After the power supply is OFF, make sure the charge LED is OFF and the residual voltage does not exist, or wait for at least 10 minutes before carrying out maintenance or inspection. Otherwise, damage or injury may be caused.

◎Modification to the AC Drive without permission is strictly prohibited, otherwise, severe injury may be caused. Arbitrarily modification of AC Drive will result in service warranty invalid.

Sheet 5-1-1 Control Command Addresses

EEPROM Addresses Introduction

The addresses listed in the sheet above is the way of writing RAM. The RAM stores the data after power-off and does not save it. In the communication mode, for the write command "06H", if the parameter needs to be stored after power-off, the method of writing EEPROM should be used. The original "0" of the most significant bit of the RAM address is changed to "F", which is converted into the corresponding EEPROM address, for example: "0XXX" is changed to "FXXX"

Example of address conversion: Upper limit frequency F006, write RAM communication address: 0006, corresponding EEPROM address: F006.

Acceleration time F010, the communication address for writing RAM is: 000A, and the corresponding address for EEPROM is: F00A.

Other parameters, are like that...

It should be noted that the erasing life of EEPROM is about 1 million times. After exceeding the erasing times, it will affect the reliability of data storage. If it is not necessary, it is recommended to control the communication by writing to RAM.
