Error Contents
The servo program designated by the SVST
program does not exist.
The axis number set for the SVST instruction is
different from the axis number set for the servo
program.
The instruction code cannot be decoded
(a non-existent instruction code has been
designated)
A virtual mode program was started in the real
mode
A real mode program was started in the virtual
mode
An instruction that cannot be used in the virtual
mode (VPF, VPR, VPSTART, ZERO, VVF, VVR,
OSC) was issued.
An axis not used in the system settings has
been set for the servo program set in a SVST
instruction.
Start attempted during processing for switching
from real mode to virtual mode.

Corrective Action
Set the correct servo program
number.
(1) Set the correct axis number.
(2) Use the SVST instruction for 4-
axes linear interpolation.
Set the correct instruction code.
Check the mode allocation for the
program.
Check the mode allocation for the
program.
Correct the servo program.
Set an axis number that is setted
in the system settings.
Use M2034 (real/virtual mode
switching request), M2044
(real/virtual mode status) as
interlocks for starting.
