Without common reference surface
With this parameter setting, the movers have the same flight height, regardless of the height of the movers. The setpoint origin, which is located on the mover surface, is not at the same height for movers of different heights. The following formula can be used to calculate the Z-position setpoints for the movers:
 | In the following example, the setpoint Z-positions are calculated for two movers of different heights. Mover A1 is 12.1 mm high and mover A2 is 13.8 mm high. Tile C is 35.2 mm high and the flight height B is 2 mm. |
| AX | B | CX | ZX |
|---|---|---|---|---|
Height [mm] | 12.1 | 2 | 35.2* | 49.3* |
Height [mm] | 12.1 | 2 | 48.8** | 62.9** |
Height [mm] | 13.8 | 2 | 35.2* | 51* |
Height [mm] | 13.8 | 2 | 48.8** | 64.6** |
* | for APM4322-0000 |
** | for APM42xx-1x00 |
If no common reference surface is specified for the reference Z-position, the mover surfaces are at different heights. The height difference between the mover surfaces and the setpoints for the Z-position of the two movers is 1.7 mm.
