5.07 Low Software EOT Limit.
Low Software End of Travel Limit (User Units). If the limit is
enabled and the DSM314 is programmed to go to a position less than the Low Software EOT, an
error will result and the DSM314 will not allow axis motion
.
If the Follower control loop is
enabled, the High Software EOT Limit is ignored for slave axis motion resulting from master axis
commands. The limit only applies to slave axis motion resulting from internally generated jog and
motion program commands.
The limit is always ignored for
Move at Velocity
%AQ commands
.
Default: -8,388,608
In Analog or Digital Servo modes,
the Low Software EOT limit is used only when the
Software
End of Travel
configuration is set to Enabled. If the Low Software EOT Limit is enabled and its
value is more negative than the Low Position Limit, the Low Software EOT Limit will internally
be set equal to the Low Position Limit Axis error code 17h will also be reported, indicating that the
limit has been adjusted.
