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-D508 driver is a closed-loop stepper motor driver and therefore provides real-time position feedback with 3-phase stepper motors equipped with encoders (NEMA size 23).
This solution combines the advantages of stepper motors and servo motors 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.
The driver has presets for ES-M32309 and ES-M32320 motors.
Unlike a traditional stepper solution, the current in the windings is not constant but is continuously adapted according to the load. Consequently, the heating is reduced and it is possible to very significantly increase the current from time to time to compensate for hard points on the movements.
