1. Product overview
Thank you for choosing Rtelligent R series digital stepper driver.
R series stepper driver, which surpasses the performance of common analog stepper driver
comprehensively based on the new 32-bit DSP platform developed by TI, and adopting the
micro-stepping technology and PID current control algorithm design. The R series stepper drivers have
the features of low noise, low vibration, low heating and high-speed high torque output, it is suitable for
most stepper motors by integrated with the micro-stepping technology.
3R60 is a digital driver for hybrid three-phase stepper motors below 60 bases.
The 3R60 driver can select the running current and subdivision through the DIP switch. There are 16
subdivisions and 8 current selections. It has overvoltage, undervoltage and overcurrent protection. Its
input and output control signals are optically isolated.
