The deviation between actual measured pitch value between any adjacent teeth and the theoretical circular pitch at the mean cone distance. Motion Drivetrain provide a single pitch error method by each flank.
This is the maximum amount of tooth runout in the radial direction, measured by indicating a pin or ball placed between two teeth at the central cone distance.

| Parameter | Description |
Dimension (Range) |
| 1. Type |
Use to set a tolerance type. - Pitch - Runout | N/A |
| 2. Gear | Use to set the target gear. | N/A |
| 3. Import |
User can use a data file for tolerance. The file format is as following. (Pitch error) - First column : Gear tooth number - Second column : Left flank error - Third column : Right flank error (Runout error) - First column : Gear tooth number - Second column : Runout error | N/A |
| 4. Data grid(Left) | Use to set left flank tolerance. | N/A |
| 5. Data grid(Right) | Use to set right flank tolerance. | N/A |
| 6. Graph(Left) | Show amount of left tolerance by using chart. | N/A |
| 7. Graph(Right) | Show amount of right tolerance by using chart | N/A |
