U-dEF
User parameter defaults
Displayed when the Up, Down, and Stop buttons are pressed
simultaneously.
• Press the Off button to proceed.
22
FAn-F
Cooling fan fault
Check and if necessary, replace the internal cooling fan.
23
0–hEAt
Ambient temperature too high
The measured temperature around the drive is above the operating
limit.
• Ensure that the drive internal cooling fan operates.
• Ensure that the required space around the drive is observed,
and that the cooling airflow path is not restricted.
• Increase the cooling airflow to the drive.
• Reduce the load on the motor or drive.
24
0–tor9
Over-current error
Current monitoring function has detected that the current levels are
above the normal operating condition for the application.
• Check that mechanical load has not changed and that the load
is not jammed or stalled.
• For pump applications, check for potential pump blockage.
25
U-tor9
Under-current error
Current monitoring function has detected that the current levels are
below the normal operating condition for the application.
• Check for mechanical breakages causing loss of load.
• Check that the motor has not become disconnected from the
drive.
26
Out-F
Drive output fault
If the fault remains, then contact your sales and service
representative.
40
AtF–01
Autotune failed
Measured motor stator resistance varies between phases.
• Ensure that the motor is correctly connected and free from
faults.
• Check the windings for correct resistance and balance.
41
AtF–02
Autotune failed
Measured motor stator resistance is too large.
• Ensure that the motor is correctly connected and free from
faults.
• Check that the power rating corresponds to the power rating of
the connected drive.
42
AtF–03
Autotune failed
Measured motor inductance is too low.
• Ensure that the motor is correctly connected and free from
faults.
43
AtF–04
Autotune failed
Measured motor inductance is too large.
• Ensure that the motor is correctly connected and free from
faults.
• Check that the power rating corresponds to the power rating of
the connected drive.
44
AtF–05
Autotune failed
Measured motor parameters are not convergent.
• Ensure that the motor is correctly connected and free from
faults.
• Check that the power rating corresponds to the power rating of
the connected drive.
50
Sc-F01
Modbus communication error
detected
A valid Modbus telegram has not been received within the
watchdog time limit that is set in P5-05:Comms loss timeout.
• Check that the network master or PLC still operates.
• Check the connection cables.
• Increase the value of P5-05:Comms loss timeout to a suitable
level.
