AS500 Series High-Performance Heavy-Duty Vector VFD


Performance Features :

·Efficient and energy-saving operating mode

The efficiency-driven energy-saving operating mode and new PWM dead-time compensation technology may effectively reduce motor loss, thereby mimizing the power consumption.


·Rapid dynamic response

Controlled with advanced motor model, it can rapidly respond to sudden changes in load even without a PG card.


·Smooth tracing starting

It can realize impact-free and smooth starting of rotating motor at any time.


·Strong grid adaptability

Automatic voltage regulation: In case of change in grid voltage, it can automatically keep the output voltage constant.

Uninterruptible operation: In case of sudden power failure, it can maintain uninterruptible operation of the converter.


·Considerate application

·PID control: The special menu is used for setting PID parameters and for calculating inside the converter, eliminating the need of an independent external regulator option.

·DC braking before operation: When the rotational direction of the motor is uncertain in free slide, it adopts DC braking and automatically restarts the motor after stopping.

·Multi-speed operation: Based on signal combinations, operating at the internally-set frequency (15-speed instructions at most) can realize continuous sequential control, and achieve low-precision position control via the limit switch.
