between the communication
card and the host controller
(or PLC).
No upgrade The burned file does not
contain a bootloader.

A position sensor position
feedback exception occurred
during positioning.
The position feedback from
the position sensor has
exceeded the maximum
software limit position.

Troubleshooting
Solution
Check the load wiring with UVW.
Check whether the value of
P92.32 is too small.
Check the ambient temperature.
Check whether load is too
heavy.
Check whether
(Mechanism overload protection
point) is too small.
Check whether P92.34 is too
small.
Check whether the brake can be
opened properly.
Check whether P92.36 is too
small.
Check AI1 wiring.
Check AI2 wiring.
Check AI3 wiring.
Check whether the
communication card wiring is
loose or dropped.
Burn the file with a bootloader
again.
You can screen out this fault by
setting P14.12. (The absence of
a bootloader does not affect the
normal running of machine.)
Check the second
encoder wiring.
Check whether
feedback from the
sensor to P17.60 and P17.61 is
normal.
Check whether the feedback
from the position sensor is
proper.
Check whether the maximum
P92.46
channel
