Fault Code Messages
Fault Code Description
Corrective Action
Factory Default parameters
have been loaded
Press STOP key, drive is ready to configure for particular application
Over current on drive output.
Excess load on the motor.
Over temperature on the drive
heatsink
Motor at constant speed: investigate overload or malfunction.
Motor starting: load stalled or jammed. Check for star-delta motor wiring
error.
Motor accelerating/decelerating: The Accel/Decel time too short
requiring too much power. If P-03 or P-04 cannot be increased, a bigger
drive is required. Cable fault between drive and motor.
.
Drive has tripped on overload
after delivering >100% of value
in P-08 for a period of time.
Check to see when the decimal points are flashing (drive in overload) and
either increase acceleration ramp (P-03) or decrease motor load. Check
cable length is within drive specification.
Check the load mechanically to
ensure it is free, and no jams, blockages or other mechanical faults exist
Brake channel over current
Over current in the brake resistor circuit. Check the cabling to the brake
resistor. Check the brake resistor value. Ensure minimum resistance
values form the rating tables are observed.
Brake resistor overload
Brake resistor overload. Increase deceleration time, reduce load inertia or
add further brake resistors in parallel. Ensure minimum resistance values
form the rating tables are observed.
Internal power stage fault
Check wiring to motor, look for ph-ph or ph-Earth short circuit. Check
drive ambient temp, additional space or cooling needed?
Check drive is not forced into overload.
.
Over voltage on DC bus
Supply problem, or increase Decel ramp time P-04.
.
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 IDL Authorised Distributor.
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.
Internal memory fault.
Parameters not saved, defaults reloaded.
Try again. If problem recurs, refer to your IDL Authorised Distributor.
Analog input current out of
range
Check input current in range defined by P-16.
