The ATLE7-H Series Standard VFD is a high-performance product integrated with vector control technology. Equipped with advanced current vector control, it can easily drive induction motors-boasting superior quality and high power density. It also delivers notable improvements in usability, maintainability, environmental friendliness, space-saving installation, and design standards, further optimizing the user experience.
Based on the motor's operating status, adjust motor parameters online to achieve optimal control of the motor.
Intelligently adjust acceleration/deceleration rate by load status; excellent current/vector control ensures stable, trip-free operation under 0.1s frequent speed alternation.
The VFD completes the identification of motor speed, direction, and phase angle within 0.2 seconds without the need for dedicated hardware detection circuits, and it smoothly tracks the starting of the freely rotating motor.
During momentary grid power loss, the VFD continues operating without shutting down using energy fed back by the motor, and resumes normal operation once power is restored.
Based on the motor' s operating status, it intelligently determines the flux braking intensity to minimize deceleration time as much as possible.
It intelligently identifies the energy-saving intensity based on the motor' s operating status, minimizing the motor' s energy consumption to the greatest extent.
DC braking can be activated at any frequency without a deceleration process.
With excellent current-limiting performance, the VFD can connect to or disconnect from the motorat will while in operation.
It adopts the international standard MODBUS communication protocol, facilitating complete network control with PLCs, HMI touchscreens, etc.
Adopting a modular design concept, it provides control for various general applications. The output capability of the ATLE7 Series has been proven to meet most industrial control requirements.
