Chapter 9 Major Positioning Control
9.1 Outline of major positioning controls
"Major positioning controls" are carried out using the "positioning data" stored in the
QD77MS.
The basic controls such as position control and speed control are executed by setting
the required items in this "positioning data", and then starting that positioning data.
The control system for the "major positioning controls" is set in setting item "
Da.2
Control system
" of the positioning data.
Control defined as a "major positioning control" carries out the following types of
control according to the "
Da.2
Control system
" setting.
However, the position loop is included for commanding to servo amplifier in the speed
control set in "
Da.2
Control system
".
Use the "speed-torque control" (Refer to Section 12.1 "Speed-torque control") to
execute the speed control not including position loop.
