Corrective Action
Parameters not saved, factory defaults are reloaded.
If problem reoccurs, 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 when signal format is set to 4-20mA.
Check the signal source and wiring to the Optidrive terminals.
Parameters not saved, factory defaults are reloaded.
If problem reoccurs, refer to your IDL Authorised Distributor.
User Parameter default has been loaded. Press the Stop key. Three button
default – see section 5.9
The connected motor PTC device has caused the drive to trip (analog input 2
configured for PTC device).
Check and if necessary, replace the drive internal cooling fan
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
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
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.
Drive output fault, refer to your IDL Authorised Distributor
Refer to your Invertek Sales Partner
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.
Check the pump system for leaks for burst pipes.
Check the Pipe fill function has been commissioned correctly (P3-16 & P3-
17)
One of the motor output phases is not connected to the drive.
Internal communication to the inserted Communications Option Module has
been lost. Check the module is correctly inserted
Internal communication to the inserted I/O Option Module has been lost.
Check the module is correctly inserted
A valid BACnet telegram has not been received within the watchdog time
limit set in P5-05
Check the network master / PLC is still operating
Check the connection cables
Increase the value of P5-05 to a suitable level
