The 2DM442 is a digital two-phase stepper drive that uses the latest 32-bit ARM processor for control. This digital drive has external subdivision, current, auxiliary function dip switches, which can be freely set according to user needs. The internal advanced drive control algorithm can ensure that the stepper motor runs accurately and stably in each speed range. Among them, the built-in subdivision algorithm can make the motor run smoothly at low speed; the mid-high speed torque compensation algorithm can maximize the torque of the motor at mid-high speeds; the self-tuning parameter algorithm can adapt to various motors and maximize the motor performance; the built-in smoothing algorithm can greatly improve the motor's acceleration and deceleration performance. In short, this digital drive can meet the needs of most occasions and is a cost-effective motion control product.
