8.4.4 Calculate the Zero Point Correction for the D Axis
PLEASE NOTE
The starting value on the axis display should be approximately 0 if the pin of the nozzle support is pointing
towards component table no. 3.
Fig. 8.4.1 0° position of the dr axis
Key to Fig. 8.4.1
To accurately calculate the zero point correction value, you require the IC head camera and a type 416 noz-
zle.
●
Place the nozzle in the correct position, as shown in Fig. 8.4.2.
●
To ensure that the nozzle is clearly visible to the IC camera, mark the tip of the nozzle with washable white
paint.
