Item Type: Stepper motor driver Model: TB6600 upgraded version DC Power Supply: 9V-40V DC power supply Eight Kinds of Output Current Available: Maximum 4.0A 6 Subdivision Modes Available: 32 subdivisions Standard Common Positive Single Pulse Interface: Yes Offline Hold Function: Support Protection: Built-in temperature protection and overcurrent protection Weight: Approx. 201 g / 7.1 oz Applicable Stepper Motors: 42, 57 and 86 type 2 phase 4 phase (4-wire 6-wire 8-wire) Definition of Terminal: Signal Input: CP+: Pulse signal input positive terminal. CP-: Pulse signal input negative terminal. DIR+: Positive end of motor forward and reverse control. DIR-: The negative end of the motor's positive and negative control. Enable+: Positive end of motor offline control. Enable-: Motor off-line control negative terminal. Motor Winding Connection: A+: Connect the A+ phase of the motor winding. A-: Connect the A-phase of the motor winding. B+: Connect B+ phase of motor winding. B-: Connect B-phase of motor winding. Working voltage connection: Volt Current Condenser: DC power supply is positive (note: 10V VCC 42V). Ground: Negative DC power supply Signal Input: Optocoupler isolation connection Two Connection Methods for Input Signal Interface: The user can adopt the common anode connection method or the common cathode connection method as needed. 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. 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. 1Stepper motor driver's quiescent current will be automatically halved and it is with 8 available output currents, which can be up to 4.0A. 2With built-in temperature protection and overcurrent protection, motor driver supports H-bridge bipolar constant-phase flow drive. 3As the upgraded version of TB6600, the subdivision is increased to 32 subdivisions, suitable for high subdivision purposes. 4Keeps input signal high-speed photoelectric isolation, driver board provide energy-saving semi-automatic current lock function. 5The semi-closed casing can adapt to more severe environment. And this driver board keeps simple installation.1 x Stepper Motor DriverThe 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. 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.
