The TB6600 5A (3.5A Rated) Stepper Motor Driver, often referred to as the HY-DIV268N-5A, is a PWM chopper-type stepping motor driver. It is a 2-phase single-chip bipolar sinusoidal micro-step driver, suitable for driving both 2-phase and 4-phase stepper motors with outer diameters of 35mm to 86mm at up to 5A (3.5A Rated).

Designed to offer high torque at high speeds, at the cost of low holding torque when not running, the TB 6600 utilizes a current loop subdivision control, which ensures a very low motor torque ripple and very smooth operation at low speeds. Despite the low holding torque, when the motors are running, this drive maintains good positional accuracy due to the high-speed torque. As such, it is most often used within CNC carvers, engravers and other machines that require high torque at high speed – in which holding torque is not vital for quality results.

The TB6600 stepper motor driver also comes with an automatic anti-overheating mechanism called a semi-flow function, in which it reduces the current of the circuit by 50% when no signals have been received for 200ms. Additionally, it is recommended to leave about 20mm of space around the unit clear, so as to ensure efficient heat dispersion and to avoid heat-related problems.

The TB6600 has been tried and tested to work perfectly with the NEMA17, NEMA23, NEMA24 and NEMA34 stepper motors.

DIP Pins SW1 to SW3: Micro Step Revolution Settings Chart

The first three DIP switches define the amount of steps that the motor must take per revolution, and essentially dictates the speed and torque as well. The following chart shows all of the options available and what settings SW1 to SW3 need to be in order to achieve desired pulse per revolution ratios.

DIP Pins SW4 to SW6: Output Current Settings

Each different type of motor will have different current input requirements, which is why the SW4, 5 and 6 DIP switches are designed to adjust output current. When setting these, try to accommodate your motors’ requirements as closely as possible.
