Ultra-silent 4-layer Substrate MKS-LV8729 Stepper Motor Driver with Heat Sink
The Ultra quiet LV8729 4-layer Substrate Stepper Motor Driver Module with 128 subdivisions is used in 3d printers and is a Best suited Moter Driver for Nema stepper motor whose current is less than 1.5A, which makes the motor steady, quiet, and precise.
The LV8729 is a PWM current-controlled micro step bipolar stepping motor driver. This driver can perform eight times of excitation of the second phase to 32W1-second phase and can drive simply by the CLK input.
It has a wide range of Operating voltage range i.e. 6V-36V, the proposed voltage is 12V Support subdivisions of 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 with product Process of four-layer PCB board. In the 64 subdivision or 128 subdivision controller, it has a better ultra-quiet effect.
Note: Please make sure the connecting direction is right, or it will probably burn the driver chip and controller board. Recommend doing a good job of cooling the module
Driver current algorithm and its adjustment:
- Driver current algorithm: i=Vref/0.5, the default Vref about 0.4V, so the default current 0.8A, and maximum current 1.5A
- Please DO NOT connect the motors when measuring the voltage, or it’s easy to burn the drive.
- Please connect both the power supply and the USB for power when measuring the voltage.
- Minor adjustment for potentiometer driver. Adjust it again after measurement to avoid burning the driver by excessive current.
- To increase the current by rotating the potentiometer clockwise slowly, and anticlockwise to reduce.
