Introduction:
The AS180 series of general-purpose variable frequency drives adopt the world-leading technology of motor control, featuring the same excellent control performance as international high-end converters as well as enhanced product reliability, environmental adaptability and customized and industrialized design.
Application: With industrial standard load, the converter holds 1.2 x overload capacity, supports three-phase AC asynchronous motors with a capacity of 2.2-400kW, and are widely applicable to various kinds of light-load devices, such as fans, water pumps and oil pumps.
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
