input.
 The power supply 5V (10V) can be input by either using the internal
power supply or preparing an external power supply. The internal power
supply outputs 5VDC across terminals 10 and 5, or 10V across terminals
10E and 5.

 When inputting 10VDC to the terminal 2, set any of "0, 2, 4, 10, 12, 14"
in Pr. 73. (The initial value is 0 to 5V)
 Setting "1 (0 to 5VDC)" or "2 (0 to 10VDC)" in Pr. 267 changes the
terminal 4 to the voltage input specification. When the AU signal turns
