MKS SERVO42C NEMA17 Closed Loop Stepper Motor Driver Low Noise for CNC 3D Printer Prevent Losing Steps Compatible with Gen L SGen L SKR 2 / V1.4 Turbo BTT Octopus V1.1 Mainboard

MKS servo42C is a product developed by MKS to meet market demand. The closed-loop motor uses the motor's rotation angle feedback to the drive circuit to detect whether every step that should be taken has been taken to prevent losing steps. If a closed loop occurs, the motor will make up or lose steps through the feedback information, and the blue LED on the closed loop module will light up..
Support 1-256 subdivision,odd subdivision (such as 11 subdivision) is also available. And support motors with 0.9 degree or 1.8 degree. Maximum speed 1000RPM. With usart interface, you can connect the computer by serial port, for parameter adjustment and query..
Position /speed/torque closed-loop, it can run at high speed without losing step. Easy to install and wire. The max printing speed can reach 150-180mm/S. Field-Oriented control, low noise, low vibration and low calorific. 4 Half bridge driver with 8 MOSFET, high operating efficiency. 14Bits magnetic encoder, high angle resolution..
Compatible with Gen L SGen L, SKR 2 / V1.4 Turbo BTT Octopus V1.1 Motherboard and other board which is seperated with drivers, that means drivers is not soldered onto the board.
