YASKAWA
TOEPYAIGA8001B GA800 Drive Maintenance & Troubleshooting
Code
Name
Causes
Possible Solutions
The feedback sensor is not operating correctly.
Examine the sensors on the control device side.
A fault occurred in the feedback input circuit of the
drive.
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 the PID feedback input is more than the level set in
b5-36
for longer than
b5-37
.
•
If detected, the terminal assigned to
H2-01 to H2-03 = 10 [MFDO Function Select = Alarm]
will be ON.
•
If the drive detects this fault, it will operate the motor as specified by the stop method set in
b5-12 [Feedback Loss Detection Select]
.

FbL
PID Feedback Loss
The
FbL
detection level is set incorrectly.
Adjust
b5-13 [PID Feedback Loss Detection Lvl]
and
b5-14 [PID
Feedback Loss Detection Time]
.
There is a problem with the PID feedback wiring.
Correct errors with the PID control wiring.
The feedback sensor is not operating correctly.
Examine the sensors on the control device side.
A fault occurred in the feedback input circuit of the
drive.
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 error if the PID feedback input is lower than the level set in
b5-13
for longer than
b5-14
.
•
If the drive detects this error, the terminal assigned to
H2-01 to H2-03 = 10 [MFDO Function Select = Alarm]
will be ON.
•
If the drive detects this error, it will operate the motor as specified by the stop method set in
b5-12 [Feedback Loss Detection Select]

HCA
High Current Alarm
The load is too heavy.
•
Decrease the load for applications with repetitive starts and
stops.
•
Replace the drive with a larger capacity model.
The acceleration time is too short.
•
Calculate the torque necessary during acceleration related to the
load inertia and the specified acceleration time.
•
Increase the values set in
C1-01, C1-03, C1-05, or C1-07
[Acceleration Times]
until you get the necessary torque.
•
Increase the values set in
C2-01 to C2-04 [S-Curve
Characteristics]
until you get the necessary torque.
•
Replace the drive with a larger capacity model.
The drive is trying to operate a specialized motor or a
motor that is larger than the maximum applicable
motor output of the drive.
•
Examine the motor nameplate, the motor, and the drive to make
sure that the drive rated current is larger than the motor rated
current.
•
Replace the drive with a larger capacity model.
The current level temporarily increased because of
speed search after a momentary power loss or while
trying to Auto Restart.
If speed search or Auto Restart cause an increase in current, the
drive can temporarily show this alarm. The time that the drive
shows the alarm is short. No more steps are necessary to clear the
alarm.
Note:
•
The drive detects this error if the drive output current is more than the overcurrent alarm level (150% of the rated current).
•
If the drive detects this error, the terminal assigned to
H2-01 to H2-03 = 10 [MFDO Function Select = Alarm]
will be ON.

L24v
Loss of External Power 24 Supply
The voltage of the backup 24 V power supply has
decreased. The main circuit power supply is operating
correctly.
•
Examine the external 24 V power supply for disconnected wires
and wiring errors and repair the problems.
•
Examine the external 24 V power supply for problems.
Note:
•
Set
o2-23 [External 24V Powerloss Detection]
to enable or disable
L24v
detection.
•
The drive will not output an alarm signal for this alarm.

Causes
Possible Solutions
LoG
Com Error / Abnormal SD card
There is not a micro SD in the keypad.
Put a micro SD card in the keypad.
•
The drive is connected to USB.
•
The number of log communication files is more
than 1000.
•
The micro SD card does not have available
memory space.
•
The line number data in a log communication file
is not correct.
•
A communication error between the keypad and
drive occurred during a log communication.
Set
o5-01 = 0 [Log Start/Stop Selection = OFF]
.
Note:
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 6A [MFDO Function Selection = Data Logger Error]
will activate.
