How does the driver control the servo motor
The servo actuator control motor has three modes of control for speed control, torque control and position control. Speed control is mainly achieved by changing the frequency of the torque, which is achieved by changing the size of the current, and the position control is achieved by the impulse signal. The specific control approach is typically based on customer needs. Servo motor drive control, the first is input parameters needed for the project in the drive, the motor starts, through encoder rapid feedback actual values, the actual value to the servo drive after comparing with original set of reference values, rapid adjustment error, on will adjust good signal to the motor, to realize the actions needed to make motor, thus achieve precise control. (feedback, regulation, this is the closed loop control of servo.)
Actually how to control the servo motor servo drive, this part don't have to do too much, in general use, just need to know about PC control servo drive!
One, with the motor control card, has special drive package, the motion control card is connected to the control port of the servo driver. Second, use motion control software, such as MACH; It is controlled by the parallel port output control signal, which controls the control port of the servo driver. Third, write drive package, drive parallel port; Four, the servo drive that carries the communication, of course need to write the drive.
