Function code 3:
 DZRN function is executed and the search for the zero point is in the negative direction with the target
frequency.
 After the DOG signal is received, the output frequency decreases to the JOG frequency and the motion
continues in the negative direction.
 The motion goes on according to the number of Z phases when the signal changes from ON to OFF after the
axis moves away from the DOG signal.

Function code 4:
 DZRN function is executed and the search for the zero point is in the negative direction with the target
frequency.
 After the DOG signal is received, the output frequency decreases to the JOG frequency and continues in the
negative direction. The output does not stop until the zero point signal changes from ON to OFF.
 After the axis moves away from the DOG signal, the output stops when the signal changes from ON to OFF and
the clear signal is be ON for about 20 milliseconds.
