Diagnostics 141
What to do
Check the temperature setting
parameters.
Check the parameter 35.02 Meas-
ured temperature 1, cooling of the
motor, value of 35.13 Temperature
1 warning limit.
Check the parameter 35.03 Meas-
ured temperature 2, cooling of the
motor, value of 35.23 Temperature
2 warning limit.
Check the sensor and change the
control board.
Check ambient condition, air flow
and fan operation, heatsink fins for
dust pick-up, motor power against
drive power.
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.
Check ambient conditions, air flow
and fan operation, dust pick-up in
heatsink fins, motor power against
drive power.
Check motor cabling and drive
module(s) cooling.
Check ambient conditions, air flow
and fan operation, dust pick-up in
heatsink fins and motor power
against drive power.
Check connections between drive
control unit and power unit and
value of parameter 95.04 Control
board supply.
