8 OUTPUT MODULE
(5) Control details
(a) The cam feed current value is continued at switching from the real mode to
virtual mode/from the virtual mode to real mode.
(b) Backlash compensation processing is continued with the settings value of
fixed parameters, even if switches the real mode/virtual mode.
(c) Upper/lower stroke limit value and speed limit value are not checked.
(6) Control change
The current value within 1 cam shaft revolution can be changed to optional value
for the cam as the control change during the virtual mode operation.
Refer to the "Q173DCPU/Q172DCPU Motion controller (SV13/SV22)
Programming Manual (Motion SFC)" for details of current value change.
