Note: If Pn000.1 is set to 5, 6, 7, or 9, the zero clamp function will become invalid when the control is changed to any
modes other than speed control.
For speed control, the zero clamp function locks the servo when the speed reference drops below the set speed
in the zero clamp level by setting Pn50D.0 to 7 (zero clamp function is always valid). The input signals
(/ZCLAMP, /P-CON) are not necessary.

Note: Even if a value that exceeds the speed of the servomotor is set, the actual speed will be limited to the maximum
speed of the servomotor.
