The Zhong Hua Jiang 110V 2.2kW CNC Variable Frequency Drive (VFD) is designed for compatible three-phase 110V asynchronous CNC spindle motors. It converts single-phase 110V, 50/60Hz input into controlled three-phase 110V output for spindle speed control in CNC routers, engraving machines and woodworking CNC equipment.
This spindle motor inverter offers a 0–400Hz output-frequency range, pre-programmed basic parameters, DSP vector control, 16-section speed control, MODBUS485 communication, Mach3 control support and an integrated braking unit for use with a compatible external braking resistor.
Important: This model is specified for three-phase 110V asynchronous CNC spindle motors. Check the motor nameplate and the VFD rated output current before selecting or commissioning the drive; it is not intended to power a 220V spindle motor.

Motor rated current, permissible VFD output current, resistor specifications and detailed terminal ratings are not provided in this product description. Confirm these from the exact model label and installation manual before purchase or electrical connection.
The VFD is supplied with basic parameters pre-programmed. According to the original product information, its default maximum frequency is 400Hz. Output frequency can be adjusted to meet the requirements of a compatible CNC spindle motor and the selected control arrangement.
Pre-programmed settings do not eliminate commissioning. Set and verify the spindle motor voltage, current, frequency, acceleration and deceleration parameters against the motor and inverter documentation before operation.
The product description specifies MODBUS485 communication and Mach3 control support. These functions can be used when the selected CNC controller, VFD terminals and communication settings are correctly matched. Refer to the applicable wiring instructions and control parameters for the specific equipment.
The integrated braking unit is described as supporting direct connection to a compatible external braking resistor to assist controlled spindle deceleration. Confirm the permitted resistance, power rating and terminal arrangement before adding a resistor. A braking resistor is not listed as an included component.
The original product description states that the cooling fan offers more than 20% higher air volume than ordinary comparison fans. It also describes an independent heat-dissipation channel intended to reduce the exposure of the internal circuit board to dust and water mist.
Maintain the ventilation clearances and environmental conditions required by the VFD manual. The cooling design does not establish an IP rating or permit operation in wet or heavily contaminated conditions.
The original product information lists built-in PID setting, speed tracking, multi-function relay output, multiple fault protection, status feedback, torque control and analog setting. These functions can assist drive monitoring and spindle operation once correctly configured for the CNC system.
Drive protection features do not replace suitable grounding, overcurrent protection, emergency-stop arrangements or correct electrical installation.
DSP vector control is described as supporting high torque during low-speed motor operation. The original description also identifies dead-zone compensation, automatic torque-difference compensation, low-frequency operation at 0.25Hz and up to 180% torque output under the applicable operating conditions.
Actual low-speed performance and motor heating depend on spindle construction, settings and load. Use the motor and VFD technical specifications to determine the appropriate operating range.
The inverter has an adjustable carrier frequency up to 16kHz and includes automatic voltage-regulation functionality according to the original product description. Select carrier-frequency settings in accordance with the drive instructions, considering electrical noise, heating and the operating environment.
The original VFD wiring illustration is retained below. Wiring must be carried out by qualified personnel using the terminal diagram and safety instructions for the exact inverter model. Disconnect and isolate power, then observe the required DC-bus discharge precautions before servicing.
The following original diagram illustrates connections between the VFD and a CNC control board. Confirm the controller signal type, terminal assignments, communication settings and power supply before making the connections.
Spindle output terminals: The original product instructions identify U / V / W as the terminals for the three-phase spindle motor. These are motor output terminals, not terminals for the incoming single-phase power supply.
Motor compatibility: This VFD is specified only for compatible three-phase 110V asynchronous CNC spindle motors. Confirm the voltage, rated current, motor power and operating frequency against the product label and manuals.
The Zhong Hua Jiang 2.2kW CNC VFD is intended for compatible spindle-speed control systems used in CNC routing, engraving and woodworking machinery. CNC equipment distributors, machine builders, integrators and maintenance professionals should check electrical and control compatibility before selecting this drive.
Motor information: Spindle nameplate voltage, phase, rated power, current and operating frequency.
