3.6.4 Position/speed control switching mode
Set " _ _ _ 1" in [Pr. PA01] to switch to the position/speed control switching mode.
(1) LOP (control switching)
Use LOP (Control switching) to switch between the position control mode and the speed control mode
with an external contact. The following shows a relation between LOP and control modes.
(Note)
LOP
Control mode
0 Position control mode
1 Speed control mode
Note. 0: Off
1: On
You can switch the control mode in the zero speed status. To ensure safety, switch modes after the
servo motor has stopped. When position control mode is switched to speed control mode, droop pulses
will be reset.
If LOP is switched on/off at the speed higher than the zero speed, the control mode cannot be changed
regardless of the speed. The following shows a switching timing chart.
