FREEZ_ST
Freeze Stat Open
The bypass detected a Freeze Stat condition.
•
Check the digital input programmed for Freeze Stat Switch (Z2-
0x = 39).
•
Check the connected device for continuity.
•
Check Bypass Digital Input Invert Settings in Z2-09 to Z2-16.

FR<MS
Freq Ref < Minimum Speed (Y1-06)
The drive frequency reference setting is less than the
value set in
Y1-06 [Minimum Speed]
in these
conditions:
•
The drive is not in PI Mode
•
The drive is running
•
Minimum Speed
is enabled (
Y1-06 > 0.00
)
•
Y1-06
>
Y4-12 [Thrust Frequency]
Increase the frequency reference to a value more than
Y1-06
.
Note:
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm]
will activate.
•
If the drive detects this error, it internally sets the frequency reference to the value set in
Y1-06
.

Freq. Reference < Thrust (Y4-12)
The drive frequency reference setting is less than the
value set in
Y4-12 [Thrust Frequency]
in these
conditions:

The drive is not in PI Mode
•
The drive is running
•
Thrust
is enabled (
Y4-11 [Thrust Acceleration

Increase the frequency reference to a value more than
Y4-12
.
Note:
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm]

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 or C1-03 [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 set to
H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm]
will activate.

HIAUX
High PI Aux Feedback Level
PI Auxiliary Feedback is more than the level set in
YF-12 [PI Aux Control High Level Detect]
for the
time set in
YF-13 [PI Aux High Level Detection Time]
in these conditions:
•
The drive operates in AUTO Mode.
•
The output frequency > 0.
•
Decrease the PI Auxiliary Feedback level to less than
YF-12
.
•
Set
YF-12
and
YF-13
correctly.
Note:
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm]
will activate.

HIFB
High Feedback Sensed
The feedback level is more than the level set in
Y1-11
[High Feedback Level]
.
•
Decrease the feedback level to less than
Y1-11
-
Y1-14
[Hysteresis Level]
.
•
Set
Y1-11
and
Y1-12
correctly.
Note:
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm]
will activate.
•
If the drive detects this error, it will respond as specified by the setting of
Y1-13 [High Feedback Selection]
.
