Cause
An error of the ABZO sensor
was detected when the control
power supply was turned on.
The motor was being rotated
when the control power supply
was turned on.
The data stored in the ABZO
sensor was damaged.
A motor that is not compatible
with the driver was connected.
Absolute positioning operation
was started in a state where the
coordinates were not set.
An error was detected during
initialization of the EtherCAT
module.
• The regeneration resistor
RGB200 is not connected
properly.
• The regeneration resistor
RGB200 was overheated
extraordinarily.
• The driver heat sink was
overheated abnormally.
Remedial action
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.
Reconsider the load conditions
so that the output shaft does not
rotate by an external force when
the control power supply is
turned on.
Execute one 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 again with
the ZSG-PRESET (40D1h) of the
maintenance command.
• Execute the Clear tripmeter
(40CFh) of the maintenance
command.
Check the motor model and the
driver model, and connect them
in a correct combination.
• Reconsider the setting of the
Permission of absolute
positioning without setting
absolute coordinates (4148h).
• Execute position preset
(P-PRESET) or return-to-home
operation.
Turn on the control power supply
again. If the alarm still cannot be
cleared, contact your nearest
Oriental Motor sales office.
• If the regeneration resistor
RGB200 is not used, short the
TH1 and TH2 terminals of the
CN1 connector.
• Connect the regeneration
resistor RGB200 properly.
• The allowable regenerative
power of the regeneration
resistor RGB200 is exceeded.
Reconsider the load and
operating conditions.
• Check if the operating sound of
the fan can be heard from the
driver in a state where the
control power supply is turned
on. The fan may stop if the
operating sound cannot be
heard. Contact your nearest
Oriental Motor sales office.
