8-4 Analog Control Parameters
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).
