Pr. L0-01 is defined as whether the reference command before PLC execution is cleared.
bit 0: before the PLC scan, whether the target frequency is cleared to be 0.
(PLC is ON, and FREQ instruction is in the program)

we force M0 to be 1, then the frequency command is 20.00 Hz. If M0 = 0, it has different
situations:
Case1: when Pr.L0-01 bit0 is 0, and M0 = 0, then the frequency command remains at 20.00 Hz.
Case2: when Pr.L0-01 bit0 is 1, and M0 = 0, then the frequency command becomes 0.00 Hz.
This is because that before the PLC scans the programs, when Pr.L0-01 bit0 = 1, the frequency
will be cleared to be 0 first; when Pr.L0-01 bit0 = 0, the action to clear the frequency to be 0 is
not performed.
