How to Synchronize Servo Motor and Stepper Motor?
The synchronous setting of stepper motors and servo motors is an important part of achieving precise control, which refers to coordinated control between multiple motors to maintain their motion consistency and accuracy. This technology is crucial in automatic control fields such as automation, robots, and CNC machine tools.
Here are some setting methods for motor synchronization:
Pulse Emission Synchronization
Pulse emission synchronization is a control method that controls the synchronous movement of the motor by transmitting synchronization pulse signals. This method is commonly used on stepper motors and servo motors.
Synchronization mechanism:
Pulse signals are sent to multiple motors simultaneously through the controller to ensure that the frequency of the signals they receive is consistent to achieve synchronous motion.
There are two connection methods when used on stepper motors:
① One driver has two motors. For example, the driver DM456AI can drive two motors at the same time and maintain synchronization.
② Use one controller, input the signals to 2 stepper drivers of the same model, and then connect 2 motors of the same model respectively. One of the drawbacks of this method is that it requires more space.
Features:
① Simple to implement, suitable for low-speed and small-scale applications. The synchronization width is within 1.5m, which can be solved by pulse synchronization.
② Relatively speaking, the deviation is large, and it is more suitable for flexible gantry working conditions that allow a certain amount of deviation.
Frequency Division Output Function to Achieve Synchronization
Use the frequency division output function to synchronize, especially the servo motor with the frequency division output function. If conditions do not allow 2 signal outputs, this method can be adopted.
For example: If the CN6 encoder frequency division output A+A- B+ B- of one T6 is connected to the pulse input of another T6, the two units will run synchronously.
Features:
① The basic principle is consistent with pulse emission synchronization, simple to implement, and suitable for low-speed and small-scale applications.
② Relatively speaking, the deviation is large, and it is more suitable for flexible gantry working conditions that allow a certain amount of deviation.
Use CAN bus and Other Protocols to Achieve Synchronous Operation
CAN (Controller Area Network) bus is a widely used communication protocol, especially suitable for real-time control and monitoring applications. Using CAN bus to realize synchronous operation of servo motors is efficient and reliable.
System design
① Controller selection: Choose a servo motor controller that supports CAN bus to ensure it can handle synchronization signals and feedback data.
② Network topology: Design a suitable network topology, such as star or bus type, to ensure stable signal transmission.
Synchronization algorithm
① Simple synchronization: After the main controller sends a synchronization command, each servo motor starts simultaneously according to the received command, which is suitable for simple synchronization requirements.
② Fine synchronization: Combined with feedback data, the main controller can adjust the operating status of each motor in real time to respond to load changes and dynamic environments, ensuring high-precision synchronous control.
