3.4.6 Torque/position control change mode
Set "0005" in parameter No. 0 to switch to the torque/position control change mode.
(1) Control change (LOP)
Use control change (LOP) to switch between the torque control mode and the position control mode
from an external contact. Relationships between LOP and control modes are indicated below.
(Note) LOP Servo control mode
0 Torque control mode
1 Position control mode
Note. 0: off
1: on
The control mode may be changed in the zero speed status.
To ensure safety, change control after the servo motor has stopped. When position control mode is
changed to torque control mode, droop pulses are reset.
If the signal has been switched on-off at the speed higher than the zero speed and the speed is then
reduced to the zero speed or less, the control mode cannot be changed. A change timing chart is shown
below.
