Stepper Motor Driver HY-DIV268N-5A - 48V/5A

HY-DIV268N-5A is is a PWM chopper-type single-chip bipolar sinusoidal micro-step stepping motor driver. 2-phase bipolar-type stepping motor can be driven by only clock signal with low vibration and high efficiency. Suitable for drive Two-phase stepping motor dynamic voltage 12V to 48V, the maximum drive current is less than 5A and having outer diameter of 35 to 86 mm.

This drive uses the current loop subdivision control, the motor torque ripple is very small, low-speed running is very smooth. High-speed torque is much higher than other two-phase drives, high positioning accuracy. Widely used in the engraving machines, CNC machine tools, packaging machinery and other high resolution requirements on the device. NEMA17, NEMA23, NEMA24 and NEMA34 stepper motors work perfectly with this HY-DIV268N-5A Stepper Driver.

Notes:

HY-DIV268N-5A motor driver is not suitable for high holding (static) torque requirements. This driver has high current drive only on the edge of the step pulse. The driver can provide high torque when motor is moving but when motor stops the holding torque will be around 1/10th of selected current setting.
If Stepper motor vibrates but does not turn in any direction make sure that your motor connections for Windings A and B are not exchanged.
If Stepper motor does not runs or locks at all make sure the Enable Signal polarity is correct.
If Stepper motor does not runs or locks at all make sure that the power to the Drive is correct
If Stepper motor does not runs or locks at all make sure the 3x SUB Switches are not all set to ON or all set to OFF
