Corrective Action
The DC Bus Ripple Voltage level can be displayed in parameter P0-22
A historical log is stored at 20ms intervals prior to a trip in parameter P0-39
Check all three supply phases are present and within the 3% supply voltage level imbalance
tolerance.
Reduce the motor load.
Drive intended for use with a 3 phase supply, one input phase has been disconnected or lost.
Refer to fault 3 above
Refer to your Invertek Sales Partner.
Parameters not saved, defaults reloaded.
Try again. If problem recurs, refer to your IDL Authorised Distributor.
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 drive terminals.
Parameters not saved, defaults reloaded.
Try again. If problem recurs, refer to your IDL Authorised Distributor.
User Parameter defaults have been loaded. Press the Stop key.
The connected motor PTC device has caused the drive to trip
Check and if necessary, replace the drive internal cooling fan
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 5.5 and 5.8 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
Drive output fault, Confirm all 3 motor phases are connected, check that output contactors
are closing fully, not arcing, or not opening whilst the drive is running.
Confirm contactor control connections to the drive are correct.
Check supply to terminal T12 is >18V, otherwise Refer to your Invertek Sales Partner
Encoder communication /data loss
Encoder Speed Error. The % error between the estimated (open loop)/measured encoder
feedback speed and the actual motor speed is greater than the value set in P6-07.

Confirm that the speed loop gains have been optimised.

In Gearless applications can be caused by excess rollback, see section 13.3.

In Gearless applications confirm the encoder offset is correct, see section 12.7.

In Geared Open loop applications this can be caused by the motor stalling, check :

Incorrect Encoder PPR count set in parameters
Encoder Channel A Fault
Encoder Channel B Fault
Encoder Channels A & B Fault
Encoder Communication loss (check Encoder wiring Connections and that encoder module is
pushed fully into the option slot of the drive)
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.
Measured motor stator resistance is too large. Ensure the motor is correctly connected
(motor contactor is closed) and free from faults. Check that the power rating corresponds to
the power rating of the connected drive.
Measured motor inductance is too low. Ensure the motor is correctly connected and free
from faults.
Measured motor inductance is too large. Ensure motor is correctly connected and free from
faults. Check that the power rating corresponds to the power rating of the connected drive.
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.
Check Brake micro-switches, brake release function and that time set in P6-13 is suitable, see
section 14.4 for further details on the "brake release monitoring" function.
One or all of the motor output phases is not connected to the drive, check that output
contactors are closing fully, not arcing, or not opening whilst the drive is running, and also
see P3-18 (Motor connected check).
A valid Modbus telegram has not been received within the watchdog time limit set in P5-06
Check the network master / PLC is still operating, Check the connection cables.
Increase the value of P5-06 to a suitable level
A valid CAN open telegram has not been received within the watchdog time limit set in P5-06
Check the network master / PLC is still operating, Check the connection cables.
Increase the value of P5-06 to a suitable level
Internal communication to the inserted Communication Option Module has been lost.
Check the module is correctly inserted
Internal communication to the inserted Option Module has been lost.
Check the module is correctly inserted

Motor data is correct and an auto-tune has been performed.
Magnetising current in P7-04 is not too high.
Brake is releasing.
