Real mode axis
information
register
Real mode axis
information register
• The information (Real mode axis: 0/Except real mode axis: 1) used as a real
mode axis at the time of switching from real mode to virtual mode is stored.
SD500 : b0 to b15 (Axis 1 to 16)
SD501 : b0 to b15 (Axis 17 to 32)
• The real mode axis information does not change at the time of switching from
virtual mode to real mode
S (At virtual mode
transition)
SD502
SD503
Servo amplifier
loading
information
Servo amplifier
loading information
• The loading status (loading: 1/non-loading: 0) of the servo amplifier checked
in initial process, and stored as the bit data.
SD502 : b0 to b15 (Axis 1 to 16)
SD503 : b0 to b15 (Axis 17 to 32)
• The axis which turned from non-loading to loading status after power-on is
handled as loaded. (However, the axis which turned from loading to non-
loading status remains as loaded.)

error information Real mode /virtual
mode switching
error code • When a mode switching error occurs in real-to-virtual or virtual-to-real
mode switching, or a mode continuation error occurs in the virtual mode, its
error information is stored. S (Occur an error)
• This signal is used to temporarily suspend SSCNET communication while
servo amplifiers and/or SSCNET cables after Axis 1 are exchanged with the
power supply ON in a Multiple CPU system.
SD508 stores the command status for "accept waiting" or "execute waiting"
during this process.

information
• Contents of the manual pulse generator axis setting error is stored when the
manual pulse generator axis setting error flag (SM513) turn on.
(Normal: 0/Setting error: 1)
SD513 : The manual pulse generator axis setting error is stored in b0 to b2
(P1 to P3).
The smoothing magnification setting is stored in b3 to b5 (P1 to P3).
SD514 : One pulse input magnification setting error is stored in b0 to b15
(axis 1 to axis 16).
SD515 : One pulse input magnification setting error is stored in b0 to b15
(axis 17 to axis 32).
