4.5.1 Gantry System - Travel Ranges and Speed Monitoring
Travel ranges and speed monitoring
The travel range of the X/Y Axis will be determined during machine calibration.
●
The end of the X Axis travel range is + or - 0.5 mm before the software limit switch, which is
1.5 mm before the buffer. A safety distance of 2.0 mm to the buffer is adequate if the X Axis
moves into this area with excessive speed.
●
The end of the Y Axis travel range is + or - 2.0 mm before the software limit switch. The Y
Axis travel range for a particular placement area is monitored in one direction by the software
limit switch and a buffer. In the other direction, there is a permanent exchange of communica-
tion between the axes and their positions.
