Software End of Travel set to Enabled - Motion Programs and Jog commands
are restricted to the High Software EOT Limit value. A Move at Velocity %AQ
Command can cause Commanded Position to exceed the EOT limit.
Commanded Position will roll over at the maximum positive and negative
position values (-
2,147,483,648 …+2,147,483,647 at 1:1 scaling).
Software End of Travel set to Disabled - The High Software EOT Limit is used as
the rollover value for Commanded Position. Motion Program, Jog and Move at
Velocity commands will all cause Commanded Position to roll over at the High
Software EOT Limit.
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. The Low
Software EOT limit is ignored for Jog commands if the Position Valid %I bit is off.
In Auxiliary Axis mode, the Low Software EOT limit has separate purposes depending
on the setting for Software End of Travel:
Software End of Travel set to Enabled - Motion Programs and Jog commands
are restricted to the Low Software EOT Limit value. A Move at Velocity %AQ
Command can cause Commanded Position to exceed the EOT limit.
Commanded Position will roll over at the maximum positive and negative
position values (-
2,147,483,648 …+2,147,483,647 at 1:1 scaling).
Software End of Travel set to Disabled - The Low Software EOT Limit is used as
the rollover value for Commanded Position. Motion Program, Jog and Move at
Velocity commands will all cause Commanded Position to roll over at the Low
Software EOT Limit.
5.08 Software End of Travel. Enables or disables the High Software EOT Limit and Low
Software EOT Limit. Default: Disabled
5.09 Velocity Limit. Axis Velocity Limit (User Units/sec). The Velocity Limit applies to the
sum of all velocity command sources for an axis, including the internal path
generator and external follower master axis commands. If a servo velocity command
exceeds the limit, error code F2h will be reported and the servo command will
internally be set to the limit value. Default: 1,000,000
