Error Name Error Contents Error Processing Corrective Action
900
START instruction
setting error
The servo program designated by the SVST
program does not exist.
Positioning control does not start. Set the correct servo program
number.
(1) Set the correct axis number.
901
START instruction
setting error
The axis number set for the SVST instruction is
different from the axis number set for the servo
program.
Positioning control does not start.
(2) Use the SVST instruction for 4-
axes linear interpolation.
902
Servo program
instruction code error
The instruction code cannot be decoded
(a non-existent instruction code has been
designated)
Positioning control does not start. Set the correct instruction code.
903 Start error
A virtual mode program was started in the real
mode
Positioning control does not start. Check the mode allocation for the
program.
904 Start error
A real mode program was started in the virtual
mode
Positioning control does not start. Check the mode allocation for the
program.
905 Start error
An instruction that cannot be used in the virtual
mode (VPF, VPR, VPSTART, ZERO, VVF, VVR,
OSC) was issued.
Positioning control does not start. Correct the servo program.
906 Axis No. setting error
An axis not used in the system settings has
been set for the servo program set in a SVST
instruction.
Positioning control does not start. Set an axis number that is setted
in the system settings.
907 Start error
Start attempted during processing for switching
from real mode to virtual mode.
908 Start error
Start attempted during processing for switching
from virtual mode to real mode.
Positioning control does not start. Use M2034 (real/virtual mode
switching request), M2044
(real/virtual mode status) as
interlocks for starting.
