③ Sequence of machine zero return
When the BIT0 (ZMX) of the bit parameter No.006 is set to 0, and the BIT5(DECI) of the bit
parameter No.004 is set to 0, the system chooses the machine zero return mode B, and the
deceleration signal low level is active.
So the sequence of machine zero return mode B is shown as follows:
