I am working on an application involving a servo that moves back and forth between four stations, each equipped with a sensor. The servo initially moves at a controlled speed, but switches to position control mode in INC mode when a sensor at each station detects its position. Despite referring to the manual and creating ladder logic accordingly, I am experiencing issues with my PLC programming on a FX5U with 40ssc-s card and MR-JE-70B amplifier. If anyone has a reference program to share, please do so.
Discover a sample program by clicking on the following link: Downloads - Program Examples / Function Blocks for Mitsubishi Electric Factory Automation MR-JE-10C. The MR-JE 200VAC Servo Amplifiers are versatile, with options up to 3kW and compatibility with both pulse train and analog interfaces in a single model.

I require programming for a B-type servo, not a C-type servo.
To troubleshoot the issue of "logic not working," it is important to understand the behavior of the servo motor. Does the servo move erratically or fail to move at all? Does it overshoot the sensor and stop, or does it continuously run without stopping? Providing specific details is crucial for us to effectively address and resolve the issue.
If you are experiencing issues with your servo, it's important to provide detailed information. Is the servo moving at all, or is it not functioning properly? Does it overshoot the sensor and then stop, or does it continue indefinitely? Please be specific in describing the servo's behavior for us to assist you effectively. In a typical scenario, the servo will start from its home position in speed control mode. However, when a sensor is triggered, it switches to position control mode and moves a specified distance in incremental positioning.
When using a servo in speed control mode, it will start from the home position, but switches to position control mode when a sensor is triggered. It then moves a specific distance in incremental positioning. If your current setup is not functioning as desired, share details and a screenshot of the code where you are changing modes for assistance in troubleshooting. Remember, no one will provide code, but assistance will be offered to fix any issues present.

Answer: 1. How can I troubleshoot PLC programming issues related to Mitsubishi servo with speed to position control switching? Answer: Troubleshooting PLC programming issues with Mitsubishi servo systems involves checking the ladder logic, ensuring proper configuration of the PLC, servo amplifier, and motion controller, and validating sensor inputs for accurate position detection.
Answer: Answer: When programming a Mitsubishi servo for speed to position control switching in a multi-station application, key considerations include setting up sensor detection logic, configuring the servo amplifier for incremental (INC) mode, and synchronizing the motion profiles with station positions.
Answer: Answer: Sharing reference programs for PLC programming of Mitsubishi servos with speed to position control switching can be helpful in understanding the implementation of ladder logic, sensor integration, and control mode switching.
