stepper motor driver Overview

SL2690A Drives are high performance digital 2-phase hybrid Stepper Drives newly released by Shenzhen Penhui Technology Co., Ltd. The Drives use PI controller to achieve low heating, low noise, low cost and high stability. The Drives have 16 selectable resolutions and 16 selectable current setting. To improve reliability, the Drives have some built-in protection functions, they alarm when over voltage,under voltage and over current. Optoelectronic isolation is employed to the input control signal
In self-running mode, the running speed could be set by SW5-SW8 switches. External control signals are also used to control the motor motions like stop, start , forward and reverse. The 4-28V signal level is used for protection of pulse, direction and enable. Integrated cooling function is built in to auto cut the current.
