Act401 series frequency converters can provide suitable solutions for simple frequency conversion control or complex and high-performance servo applications. It can drive synchronous motors and asynchronous motors, and also control servo motors with high precision and high performance, which are obviously contrary to the development trend of all experimental machine industries. The rated capacity range of act401 series frequency converter is 0.55 ~ 132kw. The voltage adopts a wide voltage design.

The whole series of products have obtained CE and UL certification, and meet the requirements of the European Union (EU). It is divided into sample wear test and bench wear test EMC specification

next, for the roving frame in textile machinery, let's talk about the synchronous control function of act401:

in the roving frame system, the frequency converter mainly controls four parts: 1) spindle wing 2) spindle 3) rib 4) drafting. The structure is shown in the following figure:

II Active drives the annual growth rate of China's chemical industry's foreign investment to about 80%. Actuator performance characteristics:

1 Advanced technology:

this product is imported from Germany with original packaging. It adopts field oriented control, including two current loops, one is to control the magnetic flux current value ISD, and the other is to control the torque current value isq. Because these two values are completely independent, the system realizes decoupling, which is equivalent to a separately excited DC motor

2. Simple structure and small volume:

the devices of the product adopt modular design, which is small in size and easy to install

3 Cost effective:

it is cheaper than similar European products

4. It can drive a variety of motor types, with self-tuning function:

it can drive 3-phase synchronous motor, 3-phase asynchronous motor, switched reluctance motor, 3-phase winding transformer, etc

5. Strong communication function:

can open, RS-485, RS-232, PROFIBUS-DP

6 It can be connected to incremental encoder and resolver:

em-enc, incremental encoder

em-res, resolver

III Specific description of synchronous control

system bus communication (can inside the driver) is used between master and slave drivers, and there is field bus communication between PLC and driver, which can facilitate PLC to read and write driver parameters. In addition, it should be noted that for slaves, we can use the system bus can inside the driver to exchange data with PLC through the master driver

first, let's explain the function of the system bus: the system bus is developed based on CAN protocol

1 Send start and stop signals to the slave,

2 The speed and phase of the slave are given

3 Transmit fault information

4 Reset function

5 Up to 64 units can be connected to the system bus

6 Time scanning function
