Cause
Total earth leakage of inverter
modules is excessive.
Intermediate circuit DC voltage
is oscillating due to missing input
power line phase or blown fuse.
Incorrect input power and motor
cable connection.
Excessive intermediate circuit
DC voltage.
Intermediate circuit DC voltage
is not sufficient.
Difference in DC voltages
between parallel-connected in-
verter modules.
Motor circuit fault due to missing
motor connection (any of the
three phases not connected). In
scalar control mode, the drive
detects fault only when the out-
put frequency is above 10% of
the motor nominal frequency.
Connect motor cable. If the drive
is in scalar mode and nominal
current of the motor is less than
1/6 of the nominal output current
of the drive, set parameter 31.19
Motor phase loss to No action
[0].
Control board temperature is too
high.
Estimated drive IGBT temperat-
ure is excessive.
Drive module temperature is ex-
cessive.
Drive IGBT temperature is ex-
cessive.
Power unit module temperature
is excessive.
Diagnostics 109
What to do
Check there are no power factor correction
capacitors or surge absorbers in motor
cable.
Measure insulation resistances of motor
cables and motor.
Contact your local ABB representative.
Check input power line fuses and there is
no input power supply imbalance.
Check input power connections.
Check overvoltage control is on, supply
voltage matches the nominal input voltage
of the drive. Check supply line for static or
transient overvoltage, brake chopper, brake
resistor and deceleration time. Use coast-
to-stop function (if applicable).
Check supply cabling, fuses and switchgear.
Check the auxiliary code (format XXXY
YYZZ). "XXX" specifies the source of the
first error (see "YYY"). "YYY" specifies the
module through which BCU control unit
channel the fault was received (1: Channel
1, 2: Channel 2, 4: Channel 3, 8: Channel
4, ..., 800: Channel 12).
Connect motor cable.
If the drive is in scalar mode and nominal
current of the motor is less than 1/6 of the
nominal output current of the drive, set
parameter 31.19 Motor phase loss to No
action [0].
Check proper cooling of the drive and auxil-
iary cooling fan.
Check ambient conditions, air flow and fan,
dust pick-up in heatsink fins and motor
power.
Check ambient temperature, air flow and
fan operation, dust pick-up in heatsink.
Clean whenever necessary.
Check ambient conditions, air flow and fan,
dust pick-up in heatsink fins and motor
power.
Check ambient conditions, air flow and fan,
dust pick-up in heatsink fins and motor
power.
