3.2 List of Functions
3.2.1 QD75 control functions
The QD75 has several functions. In this manual, the QD75 functions are categorized
and explained as follows.
(1) Main functions
1) OPR control
"OPR control" is a function that establishes the start point for carrying out
positioning control, and carries out positioning toward that start point. This is
used to return a workpiece, located at a position other than the OP when the
power is turned ON or after positioning stop, to the OP.
2) Positioning control
This control is carried out using the "positioning data" stored in the QD75.
Positioning control, such as position control and speed control, is executed by
setting the required items in this "positioning data" and starting that
positioning data.
3) Manual control
By inputting a signal into the QD75 from an external source, the QD75 will
output a random pulse train and carry out control. Use this manual control to
move the workpiece to a random position (JOG operation), and to finely
adjust the positioning (inching operation, manual pulse generator operation),
etc.
(2) Sub functions
Control compensation, control limits and various functions can be added.
(3) Common functions
Common control using the QD75 such as "parameter initialization" or "backup of
execution data" can be carried out.
