Cause
The main power supply was
shut off momentarily or the
voltage became low.
The detection temperature of
the ABZO sensor reached the
upper limit of the specification
value.
An error of the ABZO sensor
was detected during operation.
An error occurred between the
driver and the ABZO sensor.
The motor output power
reached the load factor to
detect the overload alarm. Refer
to p.217 for details.
The feedback speed of the
motor output shaft exceeded
the specification value.
The home information of the
ABZO sensor was damaged.
• The operating speed
exceeded the permissible
value of the driver.
• When the driver exceeded the
wrap range in the Cyclic
synchronous position mode,
the deviation between the
target position command
from the MainDevice and the
command position of the
driver exceeded the
specification value.
• Position preset (P-PRESET) of
the driver was executed in the
Cyclic synchronous position
mode when the motor was in
an excitation state.
The data stored in the driver
was damaged.
Remedial action
Check the input voltage of the
main power supply.
• Check the heat radiation
condition of the motor.
• Reconsider the ventilation
condition.
Turn off the main power supply
and the control power supply,
and check the connection of the
motor. After that, turn on the
main power supply and the
control power supply again.
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.
• Reduce the load.
• Increase the acceleration/
deceleration time or slow the
acceleration/deceleration rate.
• Check if the motor power line is
disconnected.
• Reconsider the Electronic gear
(6091h-01h, 02h) and set the
speed of the motor output
shaft to a value lower than the
specification value.
• If an overshoot is occurred at
the time of accelerating,
increase the acceleration time
or slow the acceleration rate.
Perform position preset
(P-PRESET) or return-to-home
operation to set the home again.
• Reduce the operating speed.
• When the driver performs
operation that exceeds the
wrap range in the Cyclic
synchronous position mode, set
the position control range of
the MainDevice according to
the wrap range.
• Put the motor in a non-
excitation state before
executing position preset
(P-PRESET) of the driver in the
Cyclic synchronous position
mode.
Initialize all parameters.
