2.3.4. End Of Travel Limit Input Interface
End of Travel (EOT) limits are required to define the end of the physical travel on linear axes. Positive or
clockwise motion is stopped by the clockwise (CW) end of travel limit input. Negative or counterclockwise
motion is stopped by the counterclockwise (CCW) end of travel limit input. The Home Limit switch can be
parameter configured for use during the home cycle, however, the CW or CCW EOT limit is typically used
instead. All of the end-of-travel limit inputs accept 5-24 VDC level signals. Limit directions are relative to the
encoder polarity in the diagnostics display (refer to Figure 2-23).
The active state of the EOT limits is software selectable (by the EndOfTravelLimitSetup
1
axis parameter).
