A4A1 IGBT overtemperature Estimated drive IGBT
temperature is excessive.
Check ambient condition, air flow
and fan operation, heatsink fins for
dust pick-up, motor power against
drive power.
A4A9 Cooling Drive module temperature is
excessive.
Check ambient temperature, drive
module cooling air flow and fan
operation, dust pick-up in the inside
of cabinet and heatsink of drive
module. Clean whenever
necessary.
A4B0 Excess temperature Power unit module temperature
is excessive.
Check ambient conditions, air flow
and fan operation, dust pick-up in
heatsink fins, motor power against
drive power.
A4B1 Excess temperature
difference
High temperature difference
between the IGBTs of different
phases.
Check motor cabling and drive
module(s) cooling.
A4F6 IGBT temperature Drive IGBT temperature is
excessive.
Check ambient conditions, air flow
and fan operation, dust pick-up in
heatsink fins and motor power
against drive power.
A580 PU communication Communication errors between
drive control unit and power unit.
Check connections between drive
control unit and power unit and
value of parameter 95.04 Control
board supply.
A581 Fan Cooling fan feedback missing. Check the auxiliary code to identify
the fan. Code 0 denotes main fan 1.
Other codes (format XYZ): “X”
specifies state code (1: ID run, 2:
normal). “Y” = 0, “Z” 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.
A582 Auxiliary fan missing An auxiliary cooling fan is stuck
or disconnected.
1 – Auxiliary fan 1 missing
2 – Auxiliary fan 2 missing
Check connection(s). Replace faulty
fan.
A590 Drive HW initialization. Drive hardware setup is
initializing.
1 - Initializing HW settings for
the first time.
See auxiliary code.
A591 Drive HW initialization Initialization of the drive
hardware.
Check the auxiliary code. See
actions for each code below.
0000 Drive hardware setup is
initializing.
Wait for the setup to initialize.
0001 Initializing HW settings for the
first time.
Wait for the setup to initialize.
A5A0 Safe torque off Safe torque off function is active. Check safety circuit connections
and parameter 95.04 Control board
supply.
A5EA Measurement circuit
