Abstract
A control method for motor driver includes: outputting a first signal from the controller to the first motor driver; making the first timer start to count for a first time; returning a first feedback signal from the first motor driver to the controller; dividing a value of a first count time of the first timer by two to get a value of a first delay time, wherein the first delay time is defined as the time of transmitting signals from the controller to the first motor driver; adding the value of the first delay time to the value of the first count time of the first timer to get a first sum; and transferring the first sum to the second timer to replace a value of a count time of the second timer.
Claims9
A motor control method comprising:
- providing:
- a controller comprising a first timer;
- and
- a first motor driver comprising a second timer;
- outputting a first signal from the controller to the first motor driver;
- making the first timer start to count for a first time;
- returning a first feedback signal from the first motor driver to the controller and stopping the first timer;
- dividing a value of a first count time of the first timer by two to get a value of a first delay time, wherein the first delay time is defined as the time of transmitting signals from the controller to the first motor driver;
- adding the value of the first delay time to the value of the first count time of the first timer to get a first sum;
- and
- transferring the first sum to the second timer to replace a value of a count time of the second timer.
A motor control system comprising:
- a controller comprising a first timer;
- a first motor driver comprising a second timer;
- wherein the controller is capable of outputting a first signal to the first motor driver to make the first timer start to count for a first time;
- wherein the first motor driver is capable of returning a first feedback signal from the first motor driver to the controller as receiving the first signal, at the same time the first timer is capable of stopping counting time;
- wherein the controller is also capable of dividing a value of a first count time of the first timer by two to get a value of a first delay time, adding the value of the first delay time to the value of the first count time of the first timer to get a first sum, and transferring the first sum to the second timer to replace a value of a count time of the second timer;
- wherein the first delay time is defined as the time of transmitting signals from the controller to the first motor driver.
