Parameter Name Function Description Setting Range Default
bE.13
Torque threshold of
overload protection
It is used to set the torque threshold at which the
overload protection is enabled.
If it is set to 0, the function is disabled.
When the AC drive runs in the forward direction,
if the output frequency reaches the value of b7.17
or reaches the constant-speed running frequency,
the output torque is detected. For details, see the
descriptions of b7.16 and b7.17.
If the output torque is larger than the setting
of bE.13, the AC drive stops automatically and
restricts forward running. After the AC drive runs in
the reverse direction, the restriction is cancelled.

bE.14 Selection of power dip
ride-through
These two parameters are used to set the power
dip ride-through function. With this function, the
AC drive can automatically reduce the max. output
frequency to maintain the full-torque output when a
sudden bus voltage dip occurs.
bE.14 =1: Power dip ride-through enabled
bE.14 = 0: Power dip ride-through disabled
bE.15 is used to set the voltage level of power dip
ride-through enabled. It is a percentage of standard
bus voltage.
