Figure C
Zero speed designation input
Position 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).
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).
