Check the temperature setting
parameters. Sensor type mismatch Incorrect temper-
ature sensor
setup A490
Check the parameter 35.02 Meas-
ured temperature 1, cooling of the
motor, value of 35.13 Temperature
1 warning limit. Measured temperature 1
exceeded warning limit. External temper-
ature 1 A491
Check the parameter 35.03 Meas-
ured temperature 2, cooling of the
motor, value of 35.23 Temperature
2 warning limit. Measured temperature 2
exceeded warning limit. External temper-
ature 2 A492
Check the sensor and change the
control board. Control board temperat-
ure is excessive. 1 – Sensor
fault. Control board
temperature. A4A0
Check ambient condition, air flow
and fan operation, heatsink fins for
dust pick-up, motor power against
drive power. Estimated drive IGBT
temperature is excessive. IGBTovertemper-
ature A4A1
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. Drive module temperature
is excessive. Cooling A4A9
Check ambient conditions, air flow
and fan operation, dust pick-up in
heatsink fins, motor power against
drive power. Power unit module temper-
ature is excessive. Excess temperat-
ure A4B0
Check motor cabling and drive
module(s) cooling. High temperature differ-
ence between the IGBTs
of different phases. Excess temperat-
ure difference A4B1
Check ambient conditions, air flow
and fan operation, dust pick-up in
heatsink fins and motor power
against drive power. Drive IGBT temperature is
excessive. IGBT temperat-
ure A4F6
Check connections between drive
control unit and power unit and
value of parameter 95.04 Control
board supply. Communication errors
between drive control unit
and power unit. PU communica-
tion A580
