Fault Code
Description
Corrective Action
.
Under voltage on DC
bus
This occurs routinely when power is switched off. If it occurs
during running, check power supply voltage.
Heatsink over
temperature
Check drive ambient temp.
Additional space or cooling required.
Under temperature
Trip occurs when ambient temperature is less than -10°C.
Temperature must be raised over -10°C in order to start the
drive.
Faulty thermistor on
heatsink
Refer to your Baldor District Office.
External trip (on digital
Input 3)
E-trip requested on digital input 3. Normally closed contact has
opened for some reason.
If motor thermistor is connected check if the motor is too hot.
Comms loss trip
Check communication link between drive and external
devices. Make sure each drive in the network has its unique
address.
Input phase loss trip
Drive intended for use with a 3 phase supply has lost one input
phase. Check incoming supply and fuses.
Phase Imbalance
Mains incoming supply voltage has an imbalance of >3% for
over 30 seconds. Check incoming supply and fuses.
Internal memory fault
Parameters not saved, defaults reloaded.
Try again. If the problem re-occurs, refer to your Baldor District
Office.
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.
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.
Spin start failure
Spin start function (P2-18=1) failed to detect motor speed
Check motor and connections. Ensure motor speed is less than
maximum speed (P1-06). Make sure motor base frequency
(P1-03) is <100Hz.
