12 Communications Fault Communications lost with PC or remote keypad. Check the cables and connections to external
devices.

13 Excessive DC ripple 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.

14 Input phase loss Drive intended for use with a 3 phase supply, one input phase has been disconnected or lost.

17 Internal memory fault Parameters not saved, defaults reloaded.
Try again. If problem recurs, refer to your IDL Authorised Distributor.

18 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. Check the signal source and wiring to the Optidrive terminals.

22 Cooling Fan Fault Check and if necessary, replace the drive internal cooling fan.

23 Ambient Temperature
High
The measured temperature around the drive is above the operating limit of the drive.
Ensure the drive internal cooling fan is operating.
Ensure that the required space around the drive as shown in sections 3.5 to 3.9 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 Maximum Torque Limit
Exceeded
The output torque limit has exceeded the drive capacity or trip threshold.
Reduce the motor load, or increase the acceleration time.

25 Output Torque Too Low Active only when hoist brake control is enabled P2-18 = 8. The torque developed prior to releasing
the motor holding brake is below the preset threshold. Contact your local Invertek Sales Partner for
further information on using the Optidrive P2 in hoist applications.


40 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 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 Measured motor inductance is too low. Ensure the motor is correctly connected and free from
faults.

43 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 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.
