Option on Drive Detected
A communications option PCB is in drive terminal
CN5.
Remove the option from the drive and install it on terminal CN5 on
the bypass controller.

WIRE Break
The analog input from the terminal set for
PID
Feedback [H3-xx = B]
is more than 21mA or less
than 3mA for longer than 1 s in these conditions:
•
b5-82 = 2 [Feedback Loss 4
～
20mA Detect Sel =
Fault]
•
b5-01 ≠ 0 [PID Mode Setting ≠ Disabled]
•
H3-01 or H3-09 = 2 [Terminal A1/A2 Signal Level
Selection = 4 to 20 mA]
Make sure that you install the PID feedback source and it operates
correctly.
Note:
•
Do a Fault Reset to clear the fault.
•
If the drive detects this fault, it will operate the motor as specified by the settings of
b5-82
.
•
Parameter
L5-42 [Feedback Loss Fault Retry Select]
sets the Auto Restart function of this fault.

Ground Fault
Overheating caused damage to the motor or the motor
insulation is not satisfactory.
Measure the motor insulation resistance, and replace the motor if
there is electrical conduction or unserviceable insulation.
The motor main circuit cable is contacting ground to
make a short circuit.
•
Examine the motor main circuit cable for damage, and repair
short circuits.
•
Measure the resistance between the motor main circuit cable and
the ground terminal. If there is electrical conduction, replace the
cable.
An increase in the stray capacitance of the cable and
the ground terminal caused an increase in the leakage
current.
•
If the wiring length of the cable is more than 100 m, decrease the
carrier frequency.
•
Decrease the stray capacitance.
There was a problem with the drive hardware.
Replace the control board or the drive. For information about
replacing the control board, contact Yaskawa or your nearest sales
representative.
Note:
•
The drive detects this fault if a current short to ground was more than 50% of rated current on the output side of the drive.
•
Do a Fault Reset to clear the fault.
•
L5-08 [Fault Reset Enable Select Grp2]
disables the Auto Restart function.
