Yaskawa CIMR-PU2A0211 [287/548] Fault detection
Digital Operator Display Fault Name
FbL
PID Feedback Loss
PID feedback loss detection is programmed to trigger a fault (b5-12 = 2 or 5) and the PID feedback level
is below the detection level set to b5-13 for longer than the time set to b5-14.
Cause Possible Solution
Parameters are set inappropriately Check b5-13 and b5-14 settings.
Incorrect PID feedback wiring Correct the wiring.
There is a problem with the feedback sensor
Check the sensor on the control side.
Replace the sensor if damaged.
Digital Operator Display Fault Name
GF
Ground Fault
A current short to ground exceeded 50% of rated current on the output side of the drive.
Setting L8-09 to 1 enables ground fault detection.
Cause Possible Solution
Motor insulation is damaged
Check the insulation resistance of the motor.
Replace the motor.
A damaged motor cable is creating a short
circuit
Check the motor cable.
Remove the short circuit and reapply power to the drive
Check the resistance between the cable and the ground terminal .
Replace the cable.
Excessive leakage current at the drive output
Reduce the carrier frequency.
Reduce the amount of stray capacitance.
The drive started to run
during a current offset
fault or while coasting to a stop
Set b3-01 to 1 to enable Speed Search at Start.
Perform Speed Search 1 or 2 (H1-oo = 61 or 62) via one of the external terminals.
Hardware problem
If the problem continues, replace the control board or the entire drive. Contact Yaskawa or a Yaskawa
representative for instructions on replacing the control board.
Digital Operator Display Fault Name
LF
Output Phase Loss
Phase loss on the output side of the drive.
Setting L8-07 to 1 or 2 enables Phase Loss Detection.
Cause Possible Solution
The output cable is disconnected
Check for wiring errors and properly connect the output cable.
Correct the wiring.
The motor winding is damaged
Check the resistance between motor lines.
Replace the motor if the winding is damaged.
The output terminal is loose
Apply the tightening torque specified in this manual to fasten the terminals. Refer to Wire Gauges
and Tightening Torque on page 77 for details.
The rated current of the motor being used is
less than 5% of the drive rated current
Check the drive and motor capacities.
An output transistor is damaged
If the problem continues, replace the control board or the entire drive. Contact Yaskawa or a Yaskawa
representative for instructions on replacing the control board.
A single-phase motor is being used
The drive cannot operate a single phase motor.
Digital Operator Display Fault Name
nSE
Node Setup Error
A terminal assigned to the node setup function closed during run.
Cause Possible Solution
The node setup terminal closed during run.
Stop the drive when using the node setup function.
A Run command was issued while the node
setup function was active.
Digital Operator Display Fault Name
oC
Overcurrent
Drive sensors detected an output current greater than the specified overcurrent level.
