AC120 Series AC Variable Frequency Drives

AC120 Inverter is a compact AC driver with modular structure. Achieve open and closed loop speed and position control, can drive AC induction motor and permanent magnet servo motor, can be used in single machine and system applications, while compatible with a variety of feedback options, means that the AC120 can drive a variety of AC motor and can receive the vast majority of speed/position feedback signal formats. Based on this flexibility, customers do not even need to replace existing AC motor ports to meet the requirements of high-performance applications, achieving both time and cost savings.

Available: 380-460/500V 3-phase 0.55-1200kW and 220V240V 3-phase 0.55-7.5kW

I.Characteristics:

AC120 can be configured with 5 different control modes to meet different process requirements:

1. V/F control mode

This mode is ideal for basic single-machine or multi-motor speed control

2. Sensorless vector control (open loop vector control) mode

Using a powerful high-performance sensorless vector control algorithm, the AC120 can achieve high torque output and closed-loop speed adjustment in the full speed range (below the base frequency) without any speed feedback devices.

3. Closed-loop vector control mode

By adding an encoder feedback card, the AC120 can achieve closed-loop flux vector control performance. Zero speed can continuously output full load torque, using high dynamic response speed loop, can meet the requirements of most complex applications.

4. Quadrant 4 AFE control mode

With this control mode, perfect power (sinusoidal sweep unit power factor) feedback is achieved, including only the very low current harmonic component (THD< 5%).

5. PMAC control mode

II.Compatible motor type:

Brushless servo, induction, spindle motor, torque motor, PMAC

III.Communication interface:

RS485, Profibus, Profinet, Ethernet TCP/IP

Iv. Advantages:

· Very fast control loop response

Torque ring :62.5us /- Speed ring :62.5us /- Position ring :62.5us

· Serve complex applications

Using cutting-edge control algorithms and a high-speed microprocessor (150Mhz), the AC120 can achieve very high control bandwidth and can be used for very complex industrial applications, such as: printing, tracing, rotary cutting, composite and scuttling applications.

· Bus set value to control loop to achieve less delay

Seamlessly plugged into existing automation systems, the AC120's high-performance ports connect directly to the driver's fast control loop, enabling less latency between digital Settings transmitted across the bus and the control loop.

· Replace the analog control scheme

The existing analog - based given schemes can be replaced by digital - bus - based control schemes to reduce bandwidth loss

· Flexible feedback

The AC120 provides system designers with flexibility when choosing the type of feedback

Incremental encoder/sine and cosine encoder/rotary transformer
