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.
