Bus voltage U0-05 is higher than
the actual preset threshold, and
lasts for P0-83 setting time to
alarm.

There are two
possibilities of
bus
undervoltage: (1)
the low voltage
of power grid,
(2) the
undervoltage of
bus voltage
caused by power
failure of driver.
The former can
be remembered,
while the latter
can not.
Bus voltage U0-05 is lower than
the actual preset threshold.

Bus Voltage Charging Failure
Module temperature is too high
(Module temperature U-06 ≥ 90℃
alarm, U-06 ≥ 70℃ Warning)
Overspeed (actual speed ≥
P3-21/P3-22)
The maximum forward speed is
P3-21 and the maximum reverse
speed is P3-22.

Judging that the current motor
output torque is greater than
P3-28/P3-29 (internal
forward/reverse torque limit), and
