This article provides an online calculator for the **Indexer/ATC turret/Flying shear rotary cut mechanism** to quickly find the servo’s electronic gear ratio and provide additional simulation information to evaluate whether the system parameters meet the requirements. The steps are as follows:

- Enter the number(C) of Tools or Stations.
- Define Division, ie, How many
**PUUs**betweens 2 stations. - the Circumference(C×P) is displayed and which is used for P2-52 of Delta A2 servo.
- Enter the mechanical
**Reduction ratio**(1:1 without deceleration) - Enter
**Encoder Resolution**(PLS), PLS number per turn of the Encoder,ie,The number of PUUs required to make the motor rotate 1 turn when the electronic gear ratio is 1:1. - Press the “
**Calculate**” button to get the numerator and denominator of the E-Gear Ratio. - Enter the
**positioning time**T of each division to check whether the simulation result is satisfied?
