ZF310 Series 3 Phase 220V VFD | 0.75–5.5kW Variable Frequency Drive

Compact 3 Phase 220V VFD for Industrial Motor Speed Control

The ZF310 Series 3 Phase 220V VFD is a compact and reliable variable frequency drive designed for AC motor speed control in industrial and commercial applications. With a power range from 0.75kW to 5.5kW, the ZF310 provides precise motor control, smooth starting and stopping, and multiple protection functions in a compact design.

It is an ideal solution for machines and equipment using 3-phase 220V motors, especially in regions where 220V three-phase power is commonly used.

• Power Range: 0.75kW–5.5kW
• Input Voltage: 3-phase 220V
• Output: 3-phase variable-frequency AC output
• Control Modes: V/F control and sensorless vector control
• High Starting Torque: Up to 150% at 0.5Hz
• Frequency Control: Adjustable output frequency according to application requirements
• Detachable Keypad: Convenient parameter setting and operation
• Multiple Protection Functions: Overcurrent, overvoltage, overload and other drive protection functions
• Compact Design: Suitable for limited control-panel space
• OEM Friendly: Suitable for machine manufacturers and customized equipment

The ZF310 Series is developed for applications that require reliable and flexible control of small and medium-power three-phase AC motors.

Compared with direct-on-line motor starting, the VFD provides controlled acceleration and deceleration, helping reduce starting current and mechanical impact on the motor and driven equipment. Motor speed can be adjusted according to the actual process requirements, providing greater flexibility for different operating conditions.

The drive supports both V/F control for conventional applications and sensorless vector control when improved torque performance and speed response are required.

With a power range of 0.75kW to 5.5kW, the ZF310 can be used across a wide range of compact industrial machines.

For applications requiring better low-speed performance, the ZF310 supports sensorless vector control.

The drive calculates the motor operating condition without requiring an external encoder, allowing improved torque response and speed control while maintaining a relatively simple system structure.

The drive can provide up to 150% starting torque at 0.5Hz, depending on motor characteristics and application conditions.

This makes the ZF310 suitable for applications where the motor needs stronger starting performance than conventional V/F control can provide.

The ZF310 allows users to configure acceleration and deceleration times according to the machine requirements.

Controlled acceleration can help reduce mechanical shock during startup, while adjustable deceleration allows the motor to stop more smoothly.

The ZF310 incorporates multiple protection functions designed to help protect both the VFD and connected motor during abnormal operating conditions.

Protection functions may include:

• Overcurrent protection
• Overvoltage protection
• Undervoltage protection
• Overload protection
• Overtemperature protection
• Short-circuit protection
• Motor stall protection
• Input/output phase-loss protection depending on configuration

These functions help improve system reliability and reduce the risk of equipment damage caused by abnormal electrical or operating conditions.

The compact construction of the ZF310 makes it suitable for applications where installation space is limited.

It can be installed inside machine control panels and integrated with other automation components such as:

PLCs

Contactors

Circuit breakers

Relays

Sensors

HMI systems

Industrial control systems

The detachable keypad also makes parameter setup and commissioning more convenient.

When selecting a ZF310 VFD, customers should provide the following motor information:

Motor rated power: kW or HP

Motor rated voltage: 3-phase 220V

Motor rated current: A

Motor frequency: 50Hz or 60Hz

Motor type: Induction motor or other AC motor

Application: Pump, fan, conveyor, compressor, mixer, etc.

Required overload capacity

Installation environment

Required enclosure/IP rating

Quantity required

For applications with heavy starting loads or frequent acceleration/deceleration, motor rated current and load characteristics should be considered rather than selecting the VFD based on motor kW alone.

The ZF310 3 Phase 220V VFD is suitable for:

Industrial Automation | Manufacturing Equipment | Water Treatment | HVAC | Material Handling | Packaging Machinery | Pumps & Fans | Small Compressors | Textile Machinery | OEM Equipment
