Siemens 840D 310709 - Axis drive error in piston diameter or piston rod diameter
This alarm occurs when the piston diameter or piston rod diameter values in the drive machine data (MD 5131, MD 5132, MD 5133) are invalid, such as a piston diameter less than or equal to zero or a rod diameter exceeding the piston diameter. Correct the values in the respective MD parameters to resolve.
