Non-excitation
42h 8 Sensor error at power-on
An error of the ABZO sensor was detected when
the control power supply was turned on.
Turn off the main power supply and the control power supply, and check the
connection of the ABZO sensor. After that, turn on the main power supply
and the control power supply again.
Turn on the control
power supply again
Non-excitation
43h 8 Rotation error at power on
The motor was being rotated when the control
power supply was turned on. Reconsider the load conditions so that the motor output shaft does not
rotate by an external force when the control power supply is turned on. Turn on the control
power supply again
Non-excitation
44h 8 Encoder EEPROM error The data stored in the ABZO sensor was damaged.
Execute either of the following operations. If the same alarm is still generated,
the ABZO sensor has been damaged. Contact your nearest Oriental Motor
sales office.
• Set phase Z again with the “ZSG-PRESET” of the maintenance command.
• Execute the “Clear tripmeter” of the maintenance command.
Turn on the control
power supply again
Non-excitation
45h 8 Motor combination error
A motor not allowed to combine with the driver
was connected.
(
_
Refer to p.162 for details.)
Check the motor model and the driver model, and connect them in the
correct combination. Turn on the control
power supply again
Non-excitation
4Ah 7 Return-to-home incomplete
Absolute positioning operation was started in a
state where the position coordinate had not been
set.
Execute the position preset or return-to-home operation. Any of reset operations Excitation

Regeneration resistor overheat
(AC power input driver only)
•
The regeneration resistor RGB100 is not
connected properly.
• The regeneration resistor RGB100 was
overheated extraordinarily.
• If the regeneration resistor RGB100 is not used, short the TH1 and TH2
terminals of the CN1.
• Connect the regeneration resistor
RGB100
properly.
• The allowable regenerative power of the regeneration resistor RGB100 is
exceeded. Reconsider the load and operating conditions.
Turn on the control
power supply again
Non-excitation
53h 2 HWTO input circuit error
• The time after either the HWTO1 input or the
HWTO2 input is turned OFF until the other input
is turned OFF exceeded the value set in the
“HWTO delay time of checking dual system”
parameter.
• An error of the circuit corresponding to the
phenomenon above was detected.
• Increase the value set in the "HWTO delay time of checking dual system”
parameter.
• Check the wiring of the HWTO1 input and the HWTO2 input.
Turn on the control
power supply again
Non-excitation
60h 7 ±LS both sides active
• When the “FW-LS/RV-LS input action” parameter
is set to “2: Immediate stop with alarm” or
“3: Deceleration stop with alarm,” both the FW-LS
and RV-LS inputs were detected.
• Return-to-home operation was executed in a
state where both the FW-LS and RV-LS inputs
were detected.
Check the sensor logic installed and the “Inverting mode” parameter. Any of reset operations Excitation
61h 7 Reverse ±LS connection
The LS input opposite to the operating direction
was detected while return-to-home operation in
2-sensor mode or 3-sensor mode was performed.
Check the wiring of the sensor. Any of reset operations Excitation
62h 7 Return-to-home operation error
• An unanticipated load was applied while return-
to-home operation was performed.
• The installation positions of the FW-LS and RV-LS
sensors and the HOME sensor are near to each
other.
• Position preset processing upon completion of
return-to-home operation was failed.
• The motor exceeded the HOME sensor at
decelerating to a stop while return-to-home
operation in one-way rotation mode was
performed.
• Check the load.
• Reconsider the sensor installation positions and the starting direction of
motor operation.
• See that a load exceeding the maximum torque is not applied upon
completion of return-to-home operation.
• Reconsider the specification of the HOME sensor and the “(HOME)
Acceleration/deceleration” parameter.
Any of reset operations Excitation
63h 7 No HOMES
The HOMES input was not detected at a position
between the FW-LS input and the RV-LS input
while return-to-home operation in 3-sensor mode
was performed.
Install the HOME sensor at a position between the FW-LS and RV-LS sensors. Any of reset operations Excitation
