Auxiliary output code, auxiliary output contact
They are used to check the operation of a position control.
The auxiliary output code is a 16-bit code that can be specified for each positioning table, and enables to
monitor which positioning table is being executed.
The exeuction fo the position control can be confirmed by turning an exclusive auxiliary output contact on
for a constant time.
Software limit
Limits can be set for the absolute coordinate managed within the positioning unit RTEX. When
exceeding the setting range of the software limit, an error occurs, and the system decelerates and stops.
The decelration time can be set individually.
Linear interpolation
This is the interpolation control that controls positions as the locas of the operations of the 2-axis motor
with the grouped X axis and Y axis or 3-axis motor with the grouped X axis, Y axis and Z axis becomes a
straight line. There are two setting methods, which are a composition speed specification and long axis
speed specification.
Circular interpolation
This is the inerpolation control that controls positions as the locas of the operation of the 2-axis motor
with the grouped X axis and Y axis becomes a circular arc. Therea re tow setting methods, which are a
center point specification and pass point specification.
Spiral interpolation
This is the interpolation control that controls positions as the loca of the operation of the 3-axis motor
with the grouped X axis, Y axis and Z axis becomes a spiral. Arbitrary 2 axes describe an arc, and the
remaining one axis moves to achieve a spiral There are two setting methods, which are a center point
specification and pass point specification.
Edge type
This is one of the methods to detect the request signals allocated to this unit. It executes each requested
process by detecting a trigger that is the leading edge when the request signal turns on.
Therefore, the next request cannot be accepted until the request signal turns off.
Level type
This si one of the methods to detect the request signals allocated to this unit. It executes each requested
process by detecting a trigger that the request signal is on, and continues the requested process while
the request signal is on.
