+ Limit and - Limit Inputs
The Ultra3000 drive includes integral overtravel limit inputs on the
motor encoder connector (CN2). The logic is designed so that an open
condition will halt motion in the corresponding direction. The integral
limits are configured by the actual motor file and not software
programmable. Although typically not for use on standard servo
motors, they may be activated for linear motors or other unique
applications. Figure 2.41 shows the configuration of the +Limit and
-Limit inputs. Figure 2.42 shows a typical connection to a motor with
integral limit switches.
