Issue with Sinumerik 810 M after program upload

We lost the program from the Sinumerik PLC controller. I asked for help on this platform, and an expert suggested contacting the machine manufacturer. They (machine manufacturer) provided me with the program, which included both the machine and dresser controllers in the same folder. Uploading the program was challenging, especially since we only use the machine controller, not the dresser controller. However, I successfully loaded the program and got the machine running again.

Now, the grinder doesn't reciprocate back and forth as it should. Please check the video at this link [Video link below]. I'm not sure if this issue is due to the program or if there are additional configurations needed after uploading. I've also attached images and videos here. Another observation is that the prox sensors or limit switches that control the grinder's reciprocation appear to be always on, as shown in the image below.

If you have specific details or additional questions, feel free to ask!

• Sensors 2B4 and 2B5 remain ON at all times.
• When we start the hydraulics, the table moves toward the park position but does not reciprocate.
• LEDs 19 and 20 stay ON continuously.
