The 2HCS558 is a new type of simple stepper servo drive that perfectly integrates servo technology. This stepper servo drive adopts the latest 32-bit DSP, integrates advanced vector control and power angle closed-loop control algorithms. Compared with traditional stepper drives, it can avoid the problem of stepper motor losing steps to the greatest extent, effectively suppress motor temperature rise, significantly reduce motor vibration, and greatly enhance motor high-speed performance. The cost of this drive is 50% of that of AC servo system, and the size of the motor is compatible with traditional stepper motors, which is convenient for customers to replace and upgrade. In short, this stepper servo drive integrates the advantages of no lost step, low temperature rise, high speed, high torque and low cost. It is a cost-effective motion control product.
