Ft- 13 Excessive DC ripple Excessive DC Ripple
on Internal DC bus
The DC Bus Ripple Voltage level can be displayed in parameter P0-16.
A historical log is stored at 20ms intervals prior to a trip in parameter P0-37.
Check all three supply phases are present and within the 3% supply voltage
level imbalance tolerance.
Reduce the motor load.
If the fault persists, contact your local Invertek Drives Sales Partner.
P-o 14 Input phase loss Input phase missing

Drive intended for use with a 3 phase supply, one input phase has been
disconnected or lost.

4-20mA Signal Lost The reference signal on Analog Input 1 or 2 (Terminals 6 or 10) has dropped
below the minimum threshold of 3mA when signal format is set to 4-20mA.
Check the signal source and wiring to the Optidrive terminals.

Ensure the drive internal cooling fan is operating.
Ensure that the required space around the drive as shown in sections
3.6.
Guidelines for Enclosure mounting (IP20 Units) thru 3.8. Guidelines for
Mounting (IP55 Units) 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.
-toq
24 High motor current Motor current above
configured profile
Current Monitoring Function has detected motor 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.
-oq
25 Low motor current Motor current below
configured profile
Current Monitoring Function has detected motor 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.

26 Drive Output Fault Drive output fault Drive output fault.
Check for loose motor cables at the drive and at the motor or any termination
in between. Otherwise refer to your IDL Authorised Distributor.

tF-
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.
tF- 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.
tF- 42 Autotune fail 3 Measured motor inductance is too low. Ensure the motor is correctly
connected and free from faults.
tF-
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.
tF-
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.
