Speed and force distance are controlled, and analog input is made by P1. 0 is the largest negative, 3.3/2V is 0, 3.3V is the largest positive. B: The potentiometer has 11 scales which are turned counterclockwise to zero, clockwise to 10 and 5 in the middle.

P1: Position Feedforward Regulation P2: Position Proportional Gain Regulation P3: Position Differential Regulation P4: Speed Proportional Gain Regulation

The servo system consists of three feedback loops (position loop, speed loop and torque (current) loop). The reaction speed of the inner loop current loop is the fastest, and that of the middle loop must be higher than that of the outer loop position loop. Failure to comply with this principle will cause shock or poor reaction. The design of servo driver can ensure that the current loop has good response efficiency. Users only need to adjust the parameters of position loop and speed loop. The parameters of the system always restrict each other. If only the gain of the position loop increases, the output instructions of the position loop may become unstable, so that the response of the whole servo system may become unstable. Usually the following steps can be taken to adjust the system:

1) The position feed-forward and position differential are set as potentiometer scale (3), and the position gain and velocity gain are set at a lower scale (3), then the scale (0.5-1) lattice is reduced by increasing the velocity gain at least with vibration step by step without producing abnormal sound and vibration.

2) Increasing the position gain has at least vibration. Add position differential to no vibration.

3) Increase position feed-forward to minimize delay and overshoot.

4) If the motor has vibration during operation, the speed gain should be reduced appropriately.

5) If there is vibration when the motor stops, the position gain can be reduced or the position differential can be increased appropriately.


On the premise of no overshoot and no vibration in the whole response, the position gain should be set to the maximum. Then the velocity gain, position feed-forward and position differential are fine-tuned to find the best

value.

Control signal wiring

When the control signal is connected by a single terminal, the wiring diagram is as follows:


MCAC808


When the control signal is connected differently, the wiring diagram is as follows:

MCAC808



Note: When Vcc is 5V, R = 0

When Vcc is 12V, R = 1K, greater than 1/8W, 

when Vcc is 24V, R = 2K, greater than 1/8W resistance must be connected to the control signal terminal.


Wiring diagram

The typical wiring diagram of the servo system is as follows:


MCAC808

The driver can provide a +5V, maximum power supply of 80mA to the encoder. By using the four-fold frequency counting method, the resolution of the encoder multiplied by four is the number of pulses per turn of the servo motor.
