PMC006B4 is a micro integrated stepper motor subdivision controller, which can be directly installed on the back cover of 57 42 series stepper motor. The model driver controller adopts RS485 bus control. PMC006B4 stepper motor controller can easily realize industrial control network system with up to 120 nodes, and has excellent noise suppression and motion smoothness. PMC006B4 provides a simple and rich set of control commands, which not only greatly simplifies the complexity of the upper control system, but also retains the flexibility of control to the maximum extent. It is especially suitable for various industrial applications requiring low vibration, high precision and wide voltage range.
