ACH580 Installation, Operation and Maintenance Manual 59
ACH580-01 Installation
(none) Temperature above
warning limit
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
1 Thermistor broken Contact an ABB service
representative for control board
replacement.
A4A1 IGBT overtemperature Estimated drive IGBT
temperature is
excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
A4A9 Cooling Drive module
temperature is
excessive.
Check ambient temperature. If it
exceeds 40 Β°C/104 Β°F (IP21 frames
R4
β¦R9) or if it exceeds 50 Β°C /122 Β°F
(IP21 frames R1
β¦R9), ensure that
load current does not exceed derated
load capacity of drive. For all P55
frames, check the derating
temperatures. See chapter Technical
data, section Derating in the
Hardware manual of the drive.
Check drive module cooling air flow
and fan operation.
Check inside of cabinet and heatsink
of drive module for dust pick-up.
Clean whenever necessary.
A4B0 Excess temperature Power unit module
temperature is
excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
A4B1 Excess temperature
difference
High temperature
difference between the
IGBTs of different
phases.
Check the motor cabling.
Check cooling of drive module(s).
A4F6 IGBT temperature Drive IGBT
temperature is
excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
A581 Fan Cooling fan feedback
missing.
Check the auxiliary code to identify
the fan. Code 0 denotes main fan 1.
Other codes (format XYZ): βXβ
specifies state code (1: ID run, 2:
normal). βYβ = 0, βZβ specifies the
index of the fan (1: Main fan 1, 2:
Main fan 2, 3: Main fan 3).
Check fan operation and connection.
Replace fan if faulty.
