8-4 Analog Control Parameters
When the zero speed designation input is turned ON, the speed command is forcibly set to 0.
Set the acceleration/deceleration setting of the speed command using Soft Start Acceleration Time
(Pn312), Soft Start Deceleration Time (Pn313) or S-curve Acceleration/Deceleration Time Setting (Pn314).

When the zero speed designation input is tuned ON, the speed command is forcibly set to 0. When
the actual motor speed is less than the Position Lock Level Setting (Pn316), the operation switches
to position control and servo locks. In addition, when the zero speed designation input is turned
OFF, the operation switches to speed control.
Since the position command for position control is forced to be 0, properly set the position loop
gain, various error detection functions and other settings.
Use this parameter when the CONTROL mode Selection (Pn001) is set to 1 (speed control).
This may not operate correctly if the CONTROL mode Setting (Pn001) is set to 3 (position or speed
control) or 4 (position or torque control).
When the zero speed designation input is turned ON and the speed command is less than the
Position Lock Level Setting (Pn316), the operation switches to position control and servo locks.
When the zero speed designation input is turned ON, the speed command will never be 0. You
need to change the speed command.
Since the operation is executed as a normal position control during position control, properly set
the position loop gain, various error detection functions and other settings.
Use this parameter when the CONTROL mode Selection (Pn001) is set to 1 (speed control).
