Parameter Name Function Description Setting Range Default
bE.02
Motor overload
pending coefîš¿cient
This function is used to input a pending signal to the
control system via DO before the motor overload
protection is performed. The parameter determines
the percentage at which pending is performed
before the motor overload protection. The larger the
value is, the less advanced the pending will be.
When the accumulative output current of the AC
drive is larger than the value of the overload inverse
time-lag curve multiplied by bE.02, the DO set for
the function 9 becomes active.
50% to 100% 80%
bE.05 Overcurrent stall gain When the output current exceeds the overcurrent
stall protective current during acceleration/
deceleration of the AC drive, the AC drive stops
acceleration/deceleration and keeps running at the
current frequency reference. After the output current
decreases, the AC drive continues acceleration/
deceleration.
The overcurrent stall gain is used to adjust the
overcurrent suppression capacity of the AC drive
during acceleration/deceleration. The larger the
value is, the greater the overcurrent suppression
capacity will be. In the prerequisite of no overcurrent
occurrence, set this gain as small as possible.
For small-inertia load, the gain should be small.
Otherwise, the system dynamic response will be
slow. For large-inertia load, the gain should be
large. Otherwise, the suppression result will be
dissatisfactory and the overcurrent fault may occur.
If the gain is set to 0, the overcurrent stall protection
is disabled.
bE.05 and bE.06 are valid only in V/F control.
0 to 100 20
bE.06 Overcurrent stall
protective current
100% to 200% 150%
bE.07 Short-circuit to ground
at power-on
It is used to check whether the motor is short-
circuited to ground at power-on of the AC drive. If
this function is enabled, the drive's U, V, W have
voltage output a while after power-on.
0, 1 1
bE.08 Selection of power
input phase loss
protection
It is used to select whether to enable the power
input phase loss protection.
0: Disabled
1: Power input phase loss protection on hardware
enabled
The models of 18.5 kW and below does not support
this function.
2: Power input phase loss protection on both
hardware and software enabled
0 to 2 1
bE.09 Selection of power
output phase loss
protection
1: Enabled
0: Disabled
0, 1 1
