10h 4 Excessive position deviation
• When the motor was in a state of current ON, the
deviation between the command position and
feedback position exceeded the value set in the
“Excessive position deviation alarm” parameter in
the motor output shaft.
• A load is large, or the acceleration/deceleration
time or the acceleration/deceleration rate is too
short against the load.
• The operating range of positioning push-motion
SD operation was exceeded.
• Decrease the load.
•
Increase the acceleration/deceleration time or slow the acceleration/
deceleration rate.
• Increase the operating current.
•
Reconsider the operation data.
Any of reset operations Non-excitation
20h 5 Overcurrent
The motor, the cable, and the driver output circuit
were short-circuited.
Turn off the main power supply and the control power supply first, and check
the motor, the cable, and the driver are not damaged. After that, turn on the
main power supply and the control power supply again. If the alarm is still
not reset, the motor, the cable, or the driver may be damaged. Contact your
nearest Oriental Motor sales office.
Turn on the control
power supply again
Non-excitation
21h 2 Main circuit overheat
The internal temperature of the driver reached the
upper limit of the specification value.
Reconsider the ventilation condition. Any of reset operations Non-excitation
22h 3
Overvoltage
(AC power input driver)
• The main power supply voltage exceeded the
permissible value.
•
A large load inertia was suddenly stopped.
• Vertical operation (elevating operation) was
performed.
• Check the input voltage of the main power supply.
• Decrease the load.
• Increase the acceleration/deceleration time or slow the acceleration/
deceleration rate.
• Connect our regeneration resistor RGB100 .
Turn on the control
power supply again
Non-excitation
22h 3
Overvoltage
(DC power input driver)
• The main power supply voltage exceeded the
permissible value.
• A large load inertia was suddenly stopped.
• Vertical operation (elevating operation) was
performed.
• Check the input voltage of the main power supply.
• Decrease the load.
• Increase the acceleration/deceleration time or slow the acceleration/
deceleration rate.
Any of reset operations Non-excitation
23h 3 Main power supply OFF
The main power supply was shut off during
operation.
Check if the main power supply is properly supplied. Any of reset operations Non-excitation
25h 3 Undervoltage
The main power supply was shut off momentarily
or a voltage shortage was generated.
Check the input voltage of the main power supply. Any of reset operations Non-excitation
26h 8 Motor overheat
The detection temperature of the ABZO sensor
reached the upper limit of the specification value.
•
Check the heat radiation condition of the motor.
• Reconsider the ventilation condition.
Any of reset operations Non-excitation
28h 8 Sensor error
An error of the ABZO sensor was detected during
operation.
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 on the control
power supply again
Non-excitation
2Ah 8
ABZO sensor communication
error An error occurred between the driver and the
ABZO sensor.
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
30h 2 Overload
A load exceeding the maximum torque was
applied for the time exceeded the value set in the
“Overload alarm” parameter.
• Decrease the load.
• Increase the acceleration/deceleration time or slow the acceleration/
deceleration rate.
• Increase the operating current.
Any of reset operations Non-excitation
31h 2 Overspeed
The feedback speed of the motor output shaft
exceeded the specification value.
• Reconsider the “Electronic gear A” parameter and the “Electronic gear B”
parameter, and set the speed of the motor output shaft to less than the
specification value.
• If an overshoot is occurred at the time of accelerating, increase the
acceleration time or slow the acceleration rate.
Any of reset operations Non-excitation
33h 7 Absolute position error
The home information of the ABZO sensor was
damaged. Perform the position preset or return-to-home operation to set the home
again. Turn on the control
power supply again
Non-excitation
34h 2 Command pulse error
The command pulse frequency exceeded the
specification value.
Decrease the frequency of the command pulse. Any of reset operations Non-excitation
