2.3.4. End Of Travel Limit Inputs
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 (refer to the A3200Help file).
Limit directions are relative to the encoder polarity in the diagnostics display (refer to Figure 2-12).
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.
N O T E : The Home Limit signal is not available on the HEXRC. Theend of travel limits must be used
during homing.
