Item Type: Stepper motor driver <br>Model: TB6600 upgraded version <br>DC Power Supply: 9V-40V DC power supply <br>Eight Kinds of Output Current Available: Maximum 4.0A <br>6 Subdivision Modes Available: 32 subdivisions <br>Standard Common Positive Single Pulse Interface: Yes <br>Offline Hold Function: Support <br>Protection: Built-in temperature protection and overcurrent protection <br>Weight: Approx. 201 g / 7.1 oz <br>Applicable Stepper Motors: 42, 57 and 86 type 2 phase 4 phase (4-wire 6-wire 8-wire) <br>Definition of Terminal: <br>Signal Input: <br>⑴CP+: Pulse signal input positive terminal. <br>⑵CP-: Pulse signal input negative terminal. <br>⑶DIR+: Positive end of motor forward and reverse control. <br>⑷DIR-: The negative end of the motor's positive and negative control. <br>⑸Enable+: Positive end of motor offline control. <br>⑹Enable-: Motor off-line control negative terminal. <br>Motor Winding Connection: <br>⑴A+: Connect the A+ phase of the motor winding. <br>⑵A-: Connect the A-phase of the motor winding. <br>⑶B+: Connect B+ phase of motor winding. <br>⑷B-: Connect B-phase of motor winding. <br>Working voltage connection: <br>⑴Volt Current Condenser: DC power supply is positive (note: 10V ＜VCC ＜42V). <br>⑵Ground: Negative DC power supply <br>Signal Input: Optocoupler isolation connection <br>Two Connection Methods for Input Signal Interface: The user can adopt the common anode connection method or the common cathode connection method as needed. <br>1. Common Anode Connection Method: Connect CP+, DIR+ and EN+ to the power supply of the control system respectively. If the power supply is +5V, it can be directly connected. If the power supply is higher than +5V, an external current limiting resistor R must be added. To keep that the drive current of 8-15mA is provided to the internal optical coupling of the driver. The pulse input signal is accessed through CP-; at this time, DIR- and Enable- are active at low level. <br>2. Common Cathode Connection: Connect CP-, DIR-, Enable- to the ground terminal of the control system (SGND, isolated from the power ground); the +5V pulse input signal is added through CP+; at this time, DIR+, Enable+ are in Active high. The connection value of the current limiting resistor R is the same as the common anode connection method.<br>1、Stepper motor driver's quiescent current will be automatically halved and it is with 8 available output currents, which can be up to 4.0A. <br>2、With built-in temperature protection and overcurrent protection, motor driver supports H-bridge bipolar constant-phase flow drive. <br>3、As the upgraded version of TB6600, the subdivision is increased to 32 subdivisions, suitable for high subdivision purposes. <br>4、Keeps input signal high-speed photoelectric isolation, driver board provide energy-saving semi-automatic current lock function. <br>5、The semi-closed casing can adapt to more severe environment. And this driver board keeps simple installation.The Enable terminal can not be connected. When Enable is valid, the motor rotor isin a free state (offline state). At this time, you can manually turn the motor shaft tomake adjustments suitable for you. After manual adjustment is completed, set Enable to invalid state to continue automatic control. <br>Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.1 x Stepper Motor Driver
