In many cases, it's necessary to adjust the servo motor speed ratio according to the different products to ensure it meets the current production requirements. However, how to adjust the servo motor speed is a major problem that perplexes many. Actually, there are many methods. Let's hear the detailed introduction from the transmission network editor below.
How to adjust the speed of a servo motor?
1. If the servo motor is an AC motor, it is a DC inverter speed control for air conditioners; if the servo motor is a DC brushless motor, it is a DC power supply with a DC transformer for speed control; all servo motors can be used as "PLC motor speed control power supply circuit servo motors".
2. The start, acceleration, constant speed, deceleration, and stop commands in the servo motor speed subroutine are all generated and output by the PLC electronic counter;
3. These operating commands reach the speed control power supply circuit, which then initiates the starting, acceleration, constant speed, deceleration, and stopping of the servo motor;
4. The position loop is an electronic counter in the PLC. The number of instruction pulses from the customer is used as the minuend, and the pulses from the servo motor feedback are used as the down pulses. The output of the electronic counter is compared with the output of the comparison power supply circuit to output various operating instructions.
5. Using a speed controller to change the gear ratio is generally used in reducers with relatively low power, but the linearity is not achieved, and manual adjustment is required;
6. Modify the basic parameters of the control board to change the transmission ratio of the servo motor;
7. Use speed reducers connected together to change the transmission ratio;
8. Use relative positioning commands or precise positioning commands to change (first give a low-speed gear pulse equivalent to 100 revolutions, use the pulse to develop point m, and then use the command to return the altitude).
The above is a summary of "Servo Motor Speed Control Methods" shared by the Transmission Network editor for industrial control professionals. We hope it will be helpful to you. Due to differences in manufacturers and models, the speed control methods for many servo motors may vary slightly. If you are unsure, it is recommended to consult the manufacturer first to see if adjustments can be made before proceeding.
