oFC00
Option Not Compatible with Port
The option connected to connector CN5-C is not
compatible.
Connect the option to the correct connector.
Note:
AI-A3, DI-A3, and communication options cannot be connected
to the CN5-C connector.
oFC01
Option Fault/Connection Error
The option card connected to connector CN5-C was
changed during operation.
1.
De-energize the drive.
2.
Refer to the option card manual and correctly connect the
option card to the connector on the drive.
oFC02
Duplicate Options
The same option cards or the same type of option
cards are connected to connectors CN5-A, B, and C.
Connect the option card to the correct connector.
oFC03 to
oFC11
Option Card Error Occurred at
Option Port CN5-C
A fault occurred in the option card.
1.
De-energize the drive.
2.
Make sure that the option card is correctly connected to the
connector.
3.
If the problem continues, replace the option card.
oFC12 to
oFC17
Option Card Error Occurred at
Option Port CN5-C
A fault occurred in the option card.
1.
De-energize the drive.
2.
Make sure that the option card is correctly connected to the
connector.
3.
If the problem continues, replace the option card.
oFC50 to
oFC55
Option Card Error Occurred at
Option Port CN5-C
A fault occurred in the option card.
Refer to the manual for the PG-RT3 or PG-F3 option card.
oH
Heatsink Overheat
The ambient temperature is high and the heatsink
temperature of the drive is more than the value set in
L8-02 [Overheat Alarm Level]
.
•
Measure the ambient temperature.
•
Increase the airflow in the control panel.
•
Install a cooling device (cooling fan or air conditioner) to lower
the ambient temperature.
•
Remove objects near the drive that are producing too much heat.
oH1
Heatsink Overheat
The ambient temperature is high and the heatsink
temperature of the drive is more than the
oH1
detection level.
•
Measure the ambient temperature.
•
Increase the airflow in the control panel.
•
Install a cooling device (cooling fan or air conditioner) to lower
the ambient temperature.
•
Remove objects near the drive that are producing too much heat.
oH3
Motor Overheat (PTC Input)
The thermistor wiring that detects motor temperature
is defective.
Correct wiring errors.
oH4
Motor Overheat Fault (PTC Input)
The motor has overheated.
•
Check the load level, acceleration/deceleration time, and motor
start/stop frequency (cycle time).
•
Decrease the load.
•
Increase the values set in
C1-01 to C1-08 [Acceleration/
Deceleration Times]
.
•
Set
E2-01 [Motor Rated Current (FLA)]
correctly to the value
specified by the motor nameplate.
•
Make sure that the motor cooling system is operating correctly,
and repair or replace it if it is damaged.
•
Adjust
E1-04 to E1-10 [V/f Pattern Parameters]
. For motor 2,
adjust
E3-04 to E3-10
. Decrease the values set in
E1-08 [Mid
Point A Voltage]
and
E1-10 [Minimum Output Voltage]
.
Note:
If the values set in
E1-08
and
E1-10
are too low, the overload
tolerance will decrease at low speeds.
oL1
Motor Overload
The load is too heavy.
Decrease the load.
Note:
Reset
oL1
when
U4-16 [Motor oL1 Level]
< 100.
The acceleration/deceleration times or cycle times are
too short.
•
Examine the acceleration/deceleration times and the motor start/
stop frequencies (cycle times).
•
Increase the values set in
C1-01 to C1-08 [Acceleration/
Deceleration Times]
.
Overload occurred while running at low speed.
•
Decrease the load when running at low speed.
•
Increase the motor speed.
•
If the motor is run frequently at low speeds, replace the motor
with a larger motor or use a drive-dedicated motor.
Note:
For general-purpose motors, overload can occur while running
at low speed when operating at below the rated current.
L1-01 [Motor Overload (oL1) Protection]
is set
incorrectly.
Set
L1-01
in as specified by the motor qualities for a drive-dedicated
motor.
