Yaskawa CIMR-PU2A0004 [288/548] Fault detection
Cause Possible Solution
The motor has been damaged due to
overheating or the motor insulation is
damaged
Check the insulation resistance.
Replace the motor.
One of the motor cables has shorted out or
there is a grounding problem
Check the motor cables.
Remove the short circuit and reapply power to the drive.
Check the resistance between the motor cables and the ground terminal .
Replace damaged cables.
The load is too heavy
Measure the current flowing into the motor.
Replace the drive with a larger capacity drive if the current value exceeds the rated current.
Determine if there is sudden fluctuation in the current level.
Reduce the load to avoid sudden changes in the current level or switch to a larger drive.
The acceleration or
deceleration times are too
short
Calculate the torque needed during acceleration relative to the load inertia and the specified acceleration
time. If it is not possible to set the proper amount of torque, make the following changes:
Increase the acceleration time (C1-01, C1-03).
Increase the S-curve characteristics (C2-01 through C2-04).
Increase the capacity of the drive.
The drive is attempting to operate a specialized
motor or a motor larger than the maximum size
allowed
Check the motor capacity.
Ensure that the rated capacity of the drive is greater than or equal to the capacity rating found on the
motor nameplate.
Magnetic contactor (MC) on the output side of
the drive has turned on or off
Set up the operation sequence so the MC does not trip while the drive is outputting current.
V/f setting is not operating as expected
Check the ratios between the voltage and frequency.
Set parameters E1-04 through E1-10 appropriately.
Lower the voltage if it is too high relative to the frequency.
Excessive torque compensation
Check the amount of torque compensation.
Reduce the torque compensation gain (C4-01) until there is no speed loss and less current.
Drive fails to operate properly due to noise
interference
Review the possible solutions provided for handling noise interference.
Review the section on handling noise interference on page 319 and check the control circuit lines, main
circuit lines, and ground wiring.
Overexcitation gain is set too high
Check if the fault occurs simultaneously with overexcitation function operation.
Consider motor flux saturation and reduce the value of n3-13 (Overexcitation Deceleration Gain).
Run command was applied while motor was
coasting
Set b3-01 to 1 to enable Speed Search at Start.
Program the Speed Search command input through one of the multi-function contact input terminals
(H1-oo = 61 or 62).
The rated output current of the drive is too
small
Use a larger drive.
Digital Operator Display Fault Name
oFA00
Option Card Connection Error at Option Port CN5-A
Option compatibility error
Cause Possible Solution
The option card installed into port CN5-A is
incompatible with the drive
Check if the drive supports the option card to be installed. Contact Yaskawa for assistance.
Digital Operator Display Fault Name
oFA01
Option Card Fault at Option Port CN5-A
Option not properly connected
Cause Possible Solution
The option card connection to port CN5-A is
faulty
Turn off the power and reconnect the option card.
Check if the option card is properly plugged
into the option port. Make sure the card is fixed properly.
If the option is not a communication option card, try to use the card in a different option port. If the
option card works properly in a different option port, CN5-A is damaged, and the drive requires
replacement. If the error persists (oFb01 or oFC01 occur), replace the option card.
