|AS450 Series General Vector Frequency Inverter
AS450 series general frequency vector inverters adopt not only the technology of VF control but also speed sensorless vector control technology, closed-loop vector control technology and torque control technology as well as enhanced product reliability, environmental adaptability and customized and industrialized design.
AS450 target application object: heavy-duty with 1.5 times overload capacity, support AC induction motor and permanent magnet synchronous motor with a capacity of 1.1~355kW, and are widely applicable to various kinds of heavy-load devices, such as extruders, compressors, mixers, belt machines and so on.
·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.
High-speed upgrade: When it is light load or no load, the inverter will calculate the maximum speed atomatically according to the load in order to improve the efficiency of the equipment.
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 (16-speed instructions at most) .
Stable operation of low frequency large torque.
Accurate rotor flux directional control capability can quickly respond and stable operation even in the 0Hz load torque mutation.
The main drive and the subordinate drive is speed control,there are some small differences in speed;
The speed signal from the drive receives the main drive for follow-up is used in conjunction with the droop function (Droop).
The main drive is speed control, the subordinate drive is torque control, there can’t be any difference between the main drive and the subordinate drive.
The high-speed and accurate transmission of the main drive torque signal is transmitted to the slave drive by:
Profibus_DP communication connection, to achieve master-slave control (for high-precision master-slave control)
Analog input and output connection, to achieve master and slave control (for low speed, low accuracy control requirements of the master and slave control)
