9 MAJOR POSITIONING CONTROL
9.2.16 Speed-position switching control (INC mode)
In "speed-position switching control (INC mode)" (" Da.2
Control system = Forward
run: speed/position, Reverse run: speed/position), the pulses of the speed set in
" Da.8
Command speed" are kept output on the axial direction set to the positioning
data. When the "speed-position switching signal" is input, position control of the
movement amount set in " Da.6
Positioning address/movement amount" is exercised.
"Speed-position switching control (INC mode)" is available in two different types:
"forward run: speed/position" which starts the axis in the forward run direction and
"reverse run: speed/position" which starts the axis in the reverse run direction.
Use the detailed parameter 1 "Pr.200 Speed-position function selection" with regard to
the choice for "speed-position switching control (INC mode)".

If the set value is other than 0 and 2, it is regarded as 0 and operation is performed in the
INC mode.
For details of the setting, refer to Sections 5.2 "List of parameters".
Switching over from speed control to position control
(1) The control is switched over from speed control to position control by the
external signal "speed-position switching signal".
(2) Besides setting the positioning data, the "
Cd.24
Speed-position switching
enable flag" must also be turned ON to switch over from speed control to
position control. (If the "
Cd.24
Speed-position switching enable flag" turns
ON after the speed-position switching signal turns ON, the control will continue
as speed control without switching over to position control. Only position
control will be carried out when the "
Cd.24
Speed-position switching enable
flag" and speed-position switching signal are ON at the operation start.)
