Corrective Action
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 Optidrive 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 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
The output torque limit has exceeded the drive capacity or trip threshold
Reduce the motor load, or increase the acceleration time
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.

Encoder communication /data loss
Speed Error. The error between the measured encoder feedback speed or the estimated
rotor speed is greater than the pre-set limit allowed.
Incorrect Encoder PPR count set in parameters
Encoder Channel A Fault
Encoder Channel B Fault
Encoder Channels A & B Fault
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 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 the 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.
Applies to Frame Size 8 drives only, indicates that the incoming power supply phase sequence
is incorrect. Any 2 phases may be swapped.
One of the motor output phases is not connected to the drive.
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 P5-05 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
