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.

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.

Cooling Fan Maintenance Time
The cooling fan is at 90% of its expected performance
life.
1.
Replace the cooling fan.
2.
Set
o4-03 = 0 [Fan Operation Time Setting = 0 h]
to reset the
cooling fan operation time.
Note:
When the estimated performance life is expired, the terminal set to
H2-01 to H2-03 = 2F [MFDO Function Selection = Maintenance Notification]
will activate.

Capacitor Maintenance Time
The capacitors for the main circuit and control circuit
are at 90% of expected performance life.
Replace the control board or the drive. For information about
replacing the control board, contact Yaskawa or your nearest sales
representative.
Note:
When the estimated performance life is expired, the terminal assigned to
H2-01 to H2-03 = 2F [MFDO Function Select = Maintenance Notification]
will be ON.

performance life.
Replace the control board or the drive. For information about
replacing the control board, contact Yaskawa or your nearest sales
representative.
Note:
When the estimated performance life is expired, the terminal assigned to

IGBT Maintenance Time (50%)
The IGBT is at 50% of its expected performance life.
Check the load, carrier frequency, and output frequency.
Note:
When the estimated performance life is expired, the terminal assigned to
H2-01 to H2-03 = 2F [MFDO Function Select = Maintenance Notification]
will be ON.
