Closed Loop Servo Motors driver
Advantages :
- Closed loop => no lag or step loss
- Low heating and low noise
- Quick response without overshoot or jerk
- High torque on acceleration and deceleration
- Plug&play (no adjustment for the majority of applications)
The Leadshine ES-DH2306 driver is a new generation stepper motor driver.
It operates in a closed loop and therefore provides real-time position feedback with 3-phase stepper motors equipped with encoders (NEMA 34 and NEMA 42 size).
This solution combines the advantages of stepper motors and servomotors thanks to the management of encoders integrated into the motors.
The control interface is similar to that of a classic stepper motor driver. Since the encoder is managed directly by the driver, it can return an error signal to you in the event of a mechanical blockage (configurable tolerance window).
This solution therefore provides the positioning reliability of a servomotor but also great simplicity of implementation.
Unlike a traditional stepper solution, the current in the windings is not constant but is continuously adapted depending on the load. Consequently, the heating is reduced and it is possible to punctually increase the current very significantly to compensate for hard points on the movements.
