Reason Description
Flashover or short circuit
between output phases
and ground
Brake resistor is short
circuit (22kW and below)
Brake transistor is
damaged (22kW and
below)
Brake resistor is not
connected or working.
Over current due to that
power supply voltage
dips too much
Power supply voltage
dips too much, or high
load to too low power
supply voltage
High load at continuous
low power supply voltage
Missing phase on supply
side
KEB function triggered
but failed to hold the DC
voltage at power supply
voltage drop, due to too
less inertia or two long
time for power supply
voltage drop.
1. motor phase imbalance
2.motor cable loose
1. The input voltage is
too high;
2. The motor works in
generator mode;
3. The deceleration time
is too short;
4. The braking unit and
braking resistor are not
installed.
Too high load or the
cooling condition beyond
the specification

Suggested Handling
1.Check cable or motor
phase to ground insulation
status
2.Replace cable or motor
Check the wire of brake
resistor or Replace Brake
resistor
Contact our local support or
ABC Company to repair
Check the Brake resistor or
replace suitable Brake
resistor
Check the Power supply
Check the Power supply
Check the Power supply
1.Check the Power supply
1.Check the Power supply
2.Set suitable KEB
Threshold voltage
Check the motor phase
cable and motor.
1. Check the power supply
2. Use brake resistor or
energy feedback unit to
consume or use up the
generate energy 3. Adjust
relative parameters to avoid
the motor working in
generator mode
1. Check the load
2. Check the cooling
condition, include to clean
the airduct or replace the
fan
