Function code 2:
 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 decreases the frequency to the JOG frequency (JFreq) and
continues in the negative direction.
 When the DOG signal is left and the signal changes from ON to OFF, the specified number of pulses are output.
 The first pulse output starts.
 When the 100th pulse output completes, the PLC stops and the Completion flag is ON.

Example
When M0 is ON, outputting the pulse from Y0.0 with a frequency of 20 kHz to search for the zero point in the negative
direction. When the DOG signal is received and X0.4 is ON, it keeps moving in the negative directon with the JOG
frequency of 1 kHz. The output stops immediately after X0.4 changes from ON to OFF.
