15.6 Position Error Recovery Procedure
A position error occurs when the difference between the commanded position and the
current position is more than the maximum allowable error limit for an axis.
An error limit will happen if the dispense/spray head hits a hard stop in Manual mode, if the
speed or acceleration is set too high, or if the axes drives are not powered. Ensure the
“Emergency Stop” button is not engaged. The motor stop codes are shown in the system
messages window.
Note: Refer to Section 15.8 for more information on stop codes.
Figure 120: Position Error
To correct the position error, perform the following steps:
1. Engage the “Emergency Stop” button.
2. Open the access door.
3. Move the dispense head to the center of the work area. Engage the brake on the Z-
axis. Turn the Z-axis motor coupling by hand to move the dispense head, as
necessary.
4. Close the access door.
5. Disengage the “Emergency Stop” button.
