Introduction

This is a professional two-phase stepper motor driver. It supports speed and direction control. You can set its micro step and output current with 6 DIP switch. There are 7 kinds of micro steps (1, 2 / A, 2 / B, 4, 8, 16, 32) and 8 kinds of current control (0.5A, 1A,  1.5A, 2A, 2.5A, 2.8A, 3.0A, 3.5A) in all. And all signal terminals adopt high-speed optocoupler isolation, enhancing its anti-high-frequency interference ability.

Features:

• Support 8 kinds of current control
• Support 7 kinds of micro steps adjustable
•  The interfaces adopt high-speed optocoupler isolation
• Automatic semi-flow to reduce heat
• Large area heat sink
• Anti-high-frequency interference ability
• Input anti-reverse protection
•  Overheat, over current and short circuit protection

• Wiring instructions
  There are three input signals in all: ① Step pulse signal PUL +, PUL-; ② Direction signal DIR +, DIR-; ③ off-line signal EN +, EN-. The driver supports common-cathode and common-anode circuit, you can select one according to your demand.

Common-Anode Connection:
Connect PUL +, DIR + and EN + to the power supply of the control system. If the power supply is + 5V, it can be directly connected. If the power supply is more than + 5V, the current limiting resistor R must be added externally. To ensure that the controller pin can output 8 ~ 15mA current to drive the internal optocoupler chip. Pulse signal connects to PUL-; direction signal connects to Dir- ; Enable signal connects to EN-. As shown below:

Common-Cathode Connection:
Connect PUL -, DIR – and EN – to the ground terminal of the control system. Pulse signal connects to PUL-; direction signal connects to Dir- ; Enable signal connects to EN-. As shown below:

Note: When“EN”is in the valid state, the motor is in a free states (Off- line  mode). In this mode, you can adjust the motor shaft position manually. When“EN”is in the invalid state, the motor will be in an automatic control mode.

Stepper Motor Wiring:

Two-phase 4-wire, 6-wire, 8-wire motor wiring, as shown below:

Microcontroller Connection Diagram:

This is an example for the common-anode connection. (“EN”not connected )

Note: Please cut off the power when you connect the system, and ensure the power polar is correct. Or it will damage the controller.

DIP Switch

Micro Step Setting
The follow tablet shows the driver Micro step. You can set the motor micro step via the first three DIP switch.
Step Angle = Motor Step Angle / Micro Step E.g. An stepper motor with 1.8° step angle，the finial step angle under “Micro step 4” will be 1.8°/4=0.45°

Current Control Setting

Off-line Function (EN Terminal):

If you turn on the Off-line function, the motor will enter a free state. You can adjust  the motor shaft freely, and the pulse signal will be no response. If you turn it off, it will beback into automatic control mode
Note: Generally, EN terminal is not connected.

FAQ

Q: If the control signal is higher than 5V, how do I connect?

A: You need add a resistor in series

: After connected the power, why the motor doesn’t work? The PWR Led has been ON.

A: Please check the power supply, it must higher than 9V. And make sure the I/O limited current is higher than 5mA

: How do we know the right order of the stepper motor?

A: Please check the motor specification, it show you the right order. Or you can measure it with a multimeter.
