 21 Motor PTC over heat Motor PTC Over Temperature The connected motor PTC device has caused the drive to trip (analog input 2
configured for PTC device).
 22 Cooling Fan Fault Cooling Fan Fault Check and if necessary, replace the drive internal cooling fan
 23 Ambient Temperature
High
Ambient Temperature too
High The measured temperature around the drive is above the operating limit.
Ensure the drive internal cooling fan is operating
Ensure that the required space around the drive as shown in sections 3.8
thru 3.10 has been observed, and that the cooling airflow path to and from
the drive is not restricted
Increase the cooling airflow to the drive
Reduce the effective switching frequency setting in parameter P2-24
Reduce the load on the motor / drive
 24 Exceed max torque Over-Current Error Current Monitoring Function has detected current levels above the normal
operating condition for the application.
Check mechanical load has not changed and that the load is not jammed or
stalling.
For pump application check for potential pump blockage
For fan applications check airstream to and from the fan is not restricted
 25 Output torque too low Under-Current Error Current Monitoring Function has detected current levels below the normal
operating condition for the application.
Check for mechanical breakages causing loss of load (e.g belt break).
Check motor has not become disconnected from the drive.

 40 Autotune fail 1
Autotune Failed
Measured motor stator resistance varies between phases. Ensure the motor
is correctly connected and free from faults. Check the windings for correct
resistance and balance.
 41 Autotune fail 2 Measured motor stator resistance is too large. Ensure the motor is correctly
connected and free from faults. Check that the power rating corresponds to
the power rating of the connected drive.
 42 Autotune fail 3 Measured motor inductance is too low. Ensure the motor is correctly
connected and free from faults.
 43 Autotune fail 4 Measured motor inductance is too large. Ensure the motor is correctly
connected and free from faults. Check that the power rating corresponds to
the power rating of the connected drive.
 44 Autotune fail 5 Measured motor parameters are not convergent. Ensure the motor is
correctly connected and free from faults. Check that the power rating
corresponds to the power rating of the connected drive.
