Regenerative energy has
exceeded the capacity of
regenerative resistor .
Check the speed if it is too
high. Check the load if it is
too large or not.
lower motor rotational speed; decrease load
inertia ,increase external regenerative resistor,
improve the capacity of the driver and motor

5% or not; check encoder cable
and shielded line if it is damaged or not;
check encoder cable whether it is
intertwined with other power wire or not
Ensure power voltage of encoder
normally, ensure encoder cable and
shielded line well with FG ground,
ensure encoder cable separated with
other power wire
