Parameter Details
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).
The zero speed designation input is turned ON, and when the speed command is equal to or less
than the Position Lock Level Setting (Pn316) minus 10 r/min, operation switches to position control
and the servo lock is applied. When the speed command is equal to or more than the Position Lock
Level Setting (Pn316) plus 10 r/min, operation switches to speed control and the motor speed
follows the command speed.
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 alarm 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).
Servo locks with position control when the speed of the motor is lower than the setting of this
parameter.
The setting of this parameter is valid for both forward and reverse direction regardless of the motor
rotation direction.
