Specifications

Application areas

◆Current Vector Control

Based on the motor’s operating condition, motor parameters are adjusted online to achieve optimal control.

◆Wide speed regulation range

Output frequency: 0–1200 Hz.

◆ Adaptive Acceleration and Deceleration

Intelligently adjusts acceleration and deceleration rates based on the load’s operating conditions.

◆Excellent acceleration and deceleration performance

Superior current and voltage control technology enables rapid, alternating acceleration and deceleration in response to 0.1‑second commands, ensuring stable, trip‑free operation of the inverter.

◆ Shock-free speed tracking

No dedicated hardware detection circuitry is required; the inverter completes identification of the motor’s speed, direction, and phase angle within 0.2 seconds, enabling smooth tracking and soft-start for freely rotating motors.

◆ Continuous operation during momentary power outages

During a momentary power outage on the grid, the energy fed back by the motor enables the inverter to remain operational without shutdown, resuming normal operation once power is restored.

◆ Intelligent Flux Brake

Based on the motor’s operating status, it intelligently determines the magnetic flux braking intensity, thereby minimizing deceleration time.

◆ Intelligent Power-Saving Operation

Based on the motor’s operating status, it intelligently determines the optimal level of energy savings, thereby minimizing the motor’s energy consumption to the greatest extent.

◆ Full-range DC braking

No deceleration is required; DC braking can be initiated at any frequency.

◆ Direct switching performance

Outstanding current-limiting performance enables the inverter to connect or disconnect motors at any time during operation.

◆ Communications and Networking

It employs the internationally standardized MODBUS communication protocol, facilitating seamless integration into a complete networked control system alongside PLCs, touch screens, and other devices.

◆ Modular, flexible, and highly adaptable

Adopting a modular design philosophy, it provides users with control over a wide range of general-purpose applications, and the ATLE7 series has been proven to meet the requirements of the vast majority of industrial control applications.

◆ A wide range of hot-swappable options

It supports hot-swappable communication expansion cards and operator panels.
