(2) Real mode axis information register (SD500, SD501)
This signal is used to store the information used as a real mode axis at the time
of switching from real mode to virtual mode.
The real mode axis information does not change at the time of switching from
virtual mode to real mode.

number corresponding to each bit of word data.
(3) Servo amplifier loading information (SD502, SD503)
The mounting status of the servo amplifier is checked at the power supply on or
reset of the Multiple CPU system and its results are stored in this device.
If communication with servo amplifier stops, it is reset.
The mounting status of changed axis after the power supply on is stored.
