Set the number of pulses per servo turn. When the lead screw stroke is 32mm, the servo setting is 3200 revolutions per turn, and the maximum output of the PLC is 100K. In this way, the maximum speed of the servo can only be 1850 revolutions. How can the maximum speed be 3000 revolutions?

      Firstly, single pulse accuracy * pulse speed<=maximum output capacity of PLC pulse
      Secondly, is 32mm a stroke or a lead? If it is a lead, a servo revolution of 32mm and 3000 revolutions means nearly 100m/S. Regardless of whether it really requires such a high speed, can you handle it mechanically?
      Finally, no one stipulates that the physical displacement of a single pulse must be an integer, as long as the accuracy requirements are met, it is sufficient to select a relatively regular value that meets the speed requirements. However, when the final setting is made, it is necessary to multiply the coefficient, and it is not necessary for the PLC to calculate by human. For the PLC, calculating 1x0.1 is the same as calculating 1x0.123456. If it can be rounded, it is best not to round, because the accuracy meets the requirements
