Kin_HGantry2 (FB)¶
- FUNCTION_BLOCK Kin_HGantry2 IMPLEMENTS ISMPositionKinematics_Offset,

Transformation FB for a 2-axis H gantry.
The kinematics configuration is similar to that described in Kin_Gantry2. However, the drives are mounted stationary. They move the y-axis rail and slider by means of a drive belt on the perimeter of the frame. (see picture aside; belt in pink).
| Machine coordinate system (MCS) | |
|---|---|
| Origin | Location of the TCP when the position values of both axes are 0. | 
| X | The X axis is defined so that a positive velocity on the first axis (a0) together with a negative velocity of the same amount on the second axis (a1), leads to a movement purely along the X axis in positive direction. | 
| Y | The Y axis is defined so that negative velocities of the same amount on both axes, lead to a movement purely along the Y axis in positive direction. | 
The location of the tool coordinate system (TCS) relative to the MCS in zero position:
| Tool coordinate system (TCS) | |
|---|---|
| Origin | Relative to MCS: dX = 0 dY = 0 dZ = 0 | 
| X | Along the X-Axis of the MCS in positive direction | 
| Y | Along the Y-Axis of the MCS in positive direction | 
| Z | Along the Z-Axis of the MCS in positive direction | 
 
The transformation is adequate for the following axes configurations (other configurations can be reached by interchanging A and B):
 
 
The single axes values have the following interpretation:
| a0 | position of the 1st axis of the machine (A) | 
| a1 | position of the 2nd axis of the machine (B) |
