Explanation of Set Values
• When the zero speed designation input is ON, the speed command is forcibly set to 0.
• Set the acceleration and deceleration time settings for the speed command in Soft Start Acceleration
Time (Pn312), Soft Start Deceleration Time (Pn313), and S-curve Acceleration/Deceleration Time
Setting (Pn314).
• When the zero speed designation input is turned ON, if the speed command is equal to or less than
the Position Lock Level Setting (Pn316) minus 10 r/min, the control mode switches to position control
and the servo is locked. If the speed command becomes equal to or greater than the Position Lock
Level Setting (Pn316) plus 10 r/min, the control mode switches from position to speed control and the
motor rotates at the command speed.
• In the position control mode, the position command is forcibly set to 0. Be sure to set the position loop
gain, alarm detection, and other function settings appropriately.
• Use this parameter when Control Mode Selection (Pn001) is set to 1 (speed control).
It may not function properly when Control Mode Selection (Pn001) is set to 3 (position/speed control).

Description
0
The Zero Speed Designation Input function is disabled.
1
The speed command is 0 when Zero Speed Designation is input. (Refer to Figure A.)
2
The speed command is 0 when Zero Speed Designation is input. The Servomotor falls in a servo
lock state in the position control if the actual speed reaches the setting value or less in Position
Lock Level Setting (Pn316). (Refer to Figure B.)
3
When the Zero Speed Designation is input, the Servomotor falls in a servo lock state in the
position control if the actual speed reaches the setting value or less in Position Lock Level Setting
(Pn316). (Refer to Figure C.)
