Product Description

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.

2. characteristic

● with serial port debugging function     The ● external dial code selects the drive working mode

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

name

function

P LS +

Pulse control signal: + 5V- + 24V can be driven, the rise line is effective, whenever the pulse, the motor steps from high to low.For a reliable response to the pulse signal, the pulse width should be more than 2s.

P LS -

DIR+

Direction control signal: + 5V- + 24V can be driven, high / low level signal.To ensure reliable direction of the motor, the direction signal shall be established before the pulse signal for at least 5s.The initial operation direction of the motor is related to the motor wiring, and any interphase winding (e. g., A +, A-exchange) can change the initial operation direction of the motor.

DIR-

ENA+

Enable control signal: + 5V- + 24V can be driven, high / low level signal.To enable or prohibit motor operation.When ENA + to + 5V and ENA-to low level, the drive will cut off the current of each phase of the motor leaving the motor in a free state when the step pulse is not responsive.When this function is not required, the enabling signal end can be suspended.

ALM+

Alarm signal output: when overcurrent, overpressure and underpressure alarm occurs, the alarm signal output is effective;

ALM + connect to pull resistance to output power source positive pole, ALM-connect to signal input of controller; maximum drive current is 50mA.

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:
