DS556 Digital two-phase step drive

Product profile

Ⅰ. summary

DS556 is a new two-phase digital step drive with serial port debugging function launched by GET Technology Co., Ltd. It adopts the latest 32-bit DSP control technology and integrates MODBUS-RTU standard protocol specifications. Users can set multiple parameters such as 200-40000 through the upper computer debugging software, which greatly enriches the practical functions of the product and can meet the application needs in most occasions.

The DS556 drive adopts the control principle of servo, and integrates vector control technology, built-in differential technology and adaptive filtering technology, which greatly optimizes the performance of the step motor, with low, high speed and stable operation and small noise.Accurate and smooth pure string current vector control technology effectively reduces the motor heating.

The DS556 drive drive voltage ranges from D C 20 to 50 V with a two-phase hybrid stepping motor with a peak current below 5.6A with an external diameter of 42 to 86 m m.

3. application area

Suitable for a variety of small and medium-sized automation equipment and instruments, such as: engraving machine, marking machine, cutter, plotter, CNC machine tools, automatic assembly equipment, etc.In the user expects small noise, high speed device application effect is particularly good.

II. Electrical, mechanical and environmental indicators

1. Electrical indicators

2. Use the environment and the parameters

3. Mechanical installation diagram

Figure 1 Installation dimension diagram (unit: mm)

It is recommended to use side installation, better heat dissipation effect, when the design and installation size, pay attention to the terminal size and wiring!

4. Strengthen heat dissipation

1）The reliable operating temperature of the drive is usually within 50℃ and the motor is within 80℃;

2）It is recommended to choose the automatic half-flow mode, that is, when the motor stops, the current automatically reduces by half, to reduce the heat of the motor and the drive;

3）When installing the drive, use the side installation and form strong air convection on the drive bottom; if necessary, install the fan near the drive to form air convection, assist the drive heat dissipation, and ensure that the drive works within a reliable operating temperature range.

III. Introduction of drive interface and wiring

1. Interface description

1）Control signal interface

2）Output signal interface

3）Strong electric interface

4）232 communication interface

The serial port communication interface driven by DS556 adopts RJ12 terminal, which can be connected to PC through USB to TTL serial port conversion tool. Live plug is prohibited!At the PC end, the customer can set the required parameters, such as current, subdivision, working mode, etc., depending on the upper computer software interface.

▶ Note: The cables connected by the DS556 to the PC must be confirmed before use as special cables (randomly attached according to the user situation) to avoid damage.

5）Status indication

The green LED is the power indicator and the LED is on when the drive is on and the LED goes off when the drive is off.

The red LED is the fault indicator, which flashes for 3 seconds when the fault is eliminated by the user, the red LED is often out.Red LED flashes in 3 seconds represent different fault information, as shown in the following table:
