Overview
This reference design is based on 32-bit DSC MC56F84789, to demo a simple servo motor control solution. This reference design jump-starts your ability to leverage the NXP® DSCs' advanced feature sets via complete software, tools and hardware platform.
- Can be expended to dual servo motors control on single chip.
- Speed regulation: < 0.05% (from 0% to 100% load under nominal speed) with encoder and 32-bit speed control algorithm.
- Speed ratio: 1 : 2000 with position and speed closed loop control – intelligent PID, the minimal operational speed is up to 0.5RPM.
- Only low cost Quadrature Encoder (1000 lines) is required, HALL sensors removed.
- System dynamic response: 90Hz for speed closed loop, and 30Hz for position closed loop – PID regulator.
- Speed acceleration/deceleration: from 1 to 10,000ms (configurable).
- Brake function: regenerative braking, stop in one revolution.
- Bidirectional operation: forward and reverse with speed and torque limitation.
- Faults protection such as abnormal speed, over-/under-voltage, over-current etc.
- FreeMASTER software control interface and monitor.
