Advanced Low Voltage Variable Frequency Drive for Efficient Motor Control

Product Description

Current Vector Control

Adjust motor parameters online according to the motor's operating status to achieve optimal control of the motor.

Large Speed Range

Output frequency 0 to 3000Hz.

Adaptive Acceleration and Deceleration

Intelligently adjust the acceleration and deceleration rates based on the load operating status.

Excellent Acceleration and Deceleration Performance

Outstanding current and voltage control technology, alternating acceleration and deceleration with a command of 0.1s, ensuring stable and jump-free operation of the inverter.

 

No-impact Speed Tracking

No need for dedicated hardware detection circuits; the inverter completes the identification of motor speed, direction, and phase angle within 0.2s, smoothly tracking the start of a freely rotating motor.

 

Instant Power Loss, Continuous Operation

During instantaneous power loss in the grid, the energy fed back from the motor allows the inverter to continue operating without stopping until the power supply returns to normal.

Direct Switching Performance

Excellent current limiting performance allows the inverter to connect or disconnect the motor at will while in operation.

Intelligent Flux Braking

Intelligently determine the strength of flux braking based on the motor's operating status, minimizing deceleration time.

Communication and Networking

Adopts the internationally standard MODBUS communication protocol, facilitating complete network control with PLCs, touch screens, etc.

Intelligent Energy-saving Operation

Intelligently determine the energy-saving strength based on the motor's operating status, minimizing energy consumption during motor operation.

Modular, Flexible, Highly Adaptable

Utilizes a modular design concept to provide users with various general application controls; the output capability of ATA QBLV10 has been proven to meet the requirements of the vast majority of industrial controls.

Full-domain DC Braking

DC braking can be activated from any frequency without a deceleration process.

Rich Hot-swappable Options

Directly hot-swappable RS485 communication expansion cards and operation panels.Technical Specifications
