1.2.8 Servo Off (Mechanical handle)
General
Place the controlled axes in the servo off state; that is, they stop the
current to the servo motor, which disables position control. However,
the position detection feature functions continuously, so the current
position is not lost. These signals are used to prevent the servo motors
from overloading when the tools on the axes are mechanically clamped
under certain machining conditions on the machine, or to move the
machine by driving the motors by mechanical handles.

[Classification] Input signal
[Function] Select whether to place each axis in the servo off state.
These signals are provided for the controlled axes on a one-to-one
basis.
A number appended to a signal represents a controlled axis number.
*SVFx
x : 1 ..... Servo off for the first axis
2 ..... Servo off for the second axis
3 ..... Servo off for the third axis

[Operation] Resetting this signal to 0 specifies the servo-off state (no current is
supplied to the servo motor). Positioning control is disabled, but
position detection remains enabled; so the machine position is not lost.
This signal is valid only when parameter SVF (bit 1 of parameter No.
1802) is set to 1.
