2.4.5. End Of Travel Limit Input Interface (J103)
End of Travel (EOT) limits are used to define the end of physical travel. The EOT limit inputs accept 5-24
VDC level signals. The active state of the EOT limits is software selectable by the EndOfTravelLimitSetup
axis parameter (refer to the A3200 Help file). Limit directions are relative to the encoder polarity in the
diagnostics display (refer to
Figure 2-26 ).
Positive motion is stopped by the clockwise (CW) end of travel limit input. Negative 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.
