Delta AS Series Programming Manual page 1268

The steps for performing the functions are as below
Function code 0:
 The DZRN2 function is executed and the search for the zero point is in the negative direction with the target
frequency (TFreq).
 After the DOG signal is received, the output frequency decreases to the JOG frequency (JFreq). The output
continues in the negative direction and does not stop until the zero point signal changes from ON to OFF.
 The output stops when the signal changes from ON to OFF and the axis moves away from the DOG signal.

 The DZRN2 function is executed and the search for the zero point is in the negative direction with the target
frequency (TFreq).
 After the DOG signal is received, the output is in the positive direction with the JOG frequency (JFreq) after the
output frequency decreases, and the motion direction reverses. The output does not stop until the zero point
signal changes from ON to OFF.
 The axis moves away from the DOG signal and PLC stops when the signal changes from ON to OFF.
