Part Number:1 Input terminal wiring instructions:1>.There are three input signals,they are 1.1>.step pulse signal PUL+, PUL- ;1.2>.Direction level signal DIR+, DIR- ;1.3>.Offline signal EN+, EN-. 2>.Common anode connection: connect PUL+DIR+ EN+to the power supply of the control system respectively.The pulse input signal is connected through CP-, the direction signal is connected through DIR-, and the enable signal is connected through EN-, As shown below:3>.Common cathode connectionConnect PUL-, DIR-, EN- to the ground of the control system respectively: the pulse input signal is connected through PUL+, the direction signal is connected through DIR+, and the enable signal is connected through EN+. If a current-limiting resistor is required, the connection method of the current-limiting resistor R is the same as the common anode connection. 4>.Note:The EN terminal can be left unconnected. When EN is valid, the motor rotor is in a free state(off-line state). At this time, you can manually rotate the motor shaft to make adjustments that suit you. After the manual adjustment is completed, set EN to an invalid to continue automatic control.Specifications:Model: TB6600Input Voltage: DC 9V-40VInput Current: 5AOutput Current: 0.5A-4AMaximum Power Consumption: 160WSubdivision: 1,1,2/A,2/B,4,8,16,32Work Temperature: -10~45Storage Temperature: -40~70Work Humidity: No condensation, no dropletsGas: Combustible gas and conductive are prohibitedSize: 96mm*57mm*28mmPackage List:1 X TB6600 stepper motor driver TB6600 is a two-phase stepper motor driver, which can realize forward and reverse control. Set 3 kinds of subdivisions (1,2/A,2/B,4,8,16,32) through 7-bit DIP switch and 8 gear output current(0.5A,1.0A,1.5A,2.0A,2.5A,2.8A,3.0A,3.5A). Suitable for 42/57 type two-phase hybrid stepping motor with phase current below 4.0A and can achieve low vibration, low noise, high speed drive motor. The current is selected by the DIP switch. The interface adopts telling optical isolation. Seven subdivisions are adjustable. Large area heat sink is not afraid of high temperature environment use. Strong anti-high frequency interference ability. Automatic half flow to reduce heat generation. Input voltage anti-reverse protection. Overheating, over current and short circuit protection. Strong anti-high frequency interference ability.
