 Changing operation command source:
Regardless of whether the AC motor drive runs or stops, when the new operation command
source is the external terminals, and the terminal status (ON: RUN, OFF: STOP) are different
with the drive current status, the AC motor drive operates according to Pr.02.05.
(1) Pr.02.05 = 0 or 1: the status of the AC motor drive is not changed by the terminal status.
(2) Pr.02.05 = 3 or 4: the status of the AC motor drive is changed by the terminal status.
 When you set Pr.02.05 = 1 or 3, it does not guarantee that the drive will never run. Be careful
when using this function because the switch may bounce due to mechanical vibration or
defective switch parts.
