ERROR CODE LIST

2.4 Errors

DA8EEC-91-210-A0

2.4-17

1859

Node address setting abnormal error

DESCRIPTION

Node address setting error was detected in the servo amplifier

CAUSE

Node address set via the rotary switch on the front panel of the servo amplifier is 32 or more.

SOLUTION

Set the node address of the servo amplifier to within 31 and restart the servo amplifier.

NOTE

1860

Continual communication abnormal error

DESCRIPTION

Continual communication error was detected in the servo amplifier.

CAUSE

Trouble occurred in the network command several times in succession.

SOLUTION

Check the connector for proper connection. Replace the communication cable. If excessive noise on the

communication cable is the problem, reroute the wiring.

NOTE

1861

Communication timeout abnormal error

DESCRIPTION

Communication timeout of the servo amplifier was detected.

CAUSE

A certain period of time elapsed without receipt of a network command.

SOLUTION

Check that the communication cable between the servo amplifier and NC board is looped properly.

NOTE

1862

Cyclic data reception failure

DESCRIPTION

The servo amp could not receive the cyclic data.

CAUSE

The network command was abnormal.

SOLUTION

Please confirm the network command.

Please turn off the machine.

NOTE

1863

Emergency stop input

DESCRIPTION

Servo amplifier detected emergency stop input.

CAUSE

Emergency stop input (No. 2 pin of EMG-STP) is open.

SOLUTION

Check for any abnormality in the switch, wires and power supply connected to the emergency stop input. Especially

check for slow rise time of the control signal power.

NOTE

1864

Motor auto-recognition abnormal error

DESCRIPTION

Motor auto-recognition abnormal error occurred.

CAUSE

The motor could not adapt to that servo amp.

SOLUTION

Please confirm the specification of motor and amp.

If those specifications do not adapt please change the motor adapt to the servo amp.

Please inform us that situation.

1865

Overload warning

DESCRIPTION

Overload warning was issued.

CAUSE

Load has exceeded 85% of the alarm level.

SOLUTION

Check the torque (current) waveform for oscillation or strong vertical fluctuation.

(1) Increase the servo amplifier/motor capacity. Increase the acceleration/ deceleration time. Reduce the load.

(2) Readjust the gain.

(3) Connect the wiring of the motor according to the wiring diagrams. Replace the cable.

(4) Correct the distortion of machine. Reduce load.

(5) Measure the voltage at the electromagnetic brake terminal. Release the electromagnetic brake.

(6) Perform wiring properly so that the motor cable and encoder cable may be connected one-one-one to the

amplifier.

NOTE

1866

Regenerative overload warning

DESCRIPTION

Regenerative overload warning was issued.

CAUSE

Regenerative load has exceeded 85% of the alarm level.

SOLUTION

Check the operation pattern (Speed monitor). Check the regenerative resistor load factor and warning message for

regenerative overload. Increase the motor/servo amplifier capacity. Slack up acceleration/deceleration time. Provide

an external regenerative resistor.

Decrease the motor rotations.

NOTE

1867

Battery warning

DESCRIPTION

Battery warning was issued.

CAUSE

The absolute encoder battery voltage has dropped to approx. 3.2V or below.

SOLUTION

Replace the battery for the absolute encoder with the control power ON.

NOTE

1868

Continuous communication abnormal warning

DESCRIPTION

Continuous communication abnormal warning occured.

CAUSE

The Continuous communication abnormal count exceeded set value.

SOLUTION

Please confirm the connection of cable between motor driver and NC board.

If there are many electric noises on that cable please rewire that cable.

Finally please change that cable.

Please inform us situation.

NOTE

1869

Communication abnormal accumulation warning

DESCRIPTION

Communication error accumulation warning was issued.

CAUSE

The number of communication errors has exceeded the set value.

SOLUTION

Check the connector for proper connection. Replace the communication cable. If excessive noise on the

communication cable is the problem, reroute the wiring.

NOTE

1870

Update Counter warning

DESCRIPTION

Update counter warning was issued.

CAUSE

Command update cycle is 1 ms and the update counter value was not properly incremented continuously more than

the set value.

SOLUTION

Check if the update counter is correctly incremented. Check that the command update cycle has been set properly.

NOTE

1871

Fan lock warning

DESCRIPTION

Locked fan warning was issued.

CAUSE

Cooling fan built in the servo amplifier was stopped for more than 1 s.

SOLUTION

If this warning persists, the fan may be faulty. In such a case, the temperature inside the servo amplifier rises,

possibly shortening its useful life. Inform us of the problem.

NOTE

1872

External scale warning

DESCRIPTION

External scale warning was issued.

CAUSE

External scale temperature is 65°C or higher, or signal strength is insufficient.

SOLUTION

Check the specifications of the external scale.

NOTE

1873

Ring communication is not connect

DESCRIPTION

The Ring communication was not able to be established at power supply ON.

CAUSE

There is no power to supply Ring IO board.

Disconnection or pull out optical cable.

SOLUTION

Please confirm the state of the power supply of the Ring IO load board.

Please confirm the state of the optical cable.

NOTE

1874

Ring communication time out

DESCRIPTION

Ring communication was time-out.

CAUSE

By the optical cable omission on reception side etc. after establishing the communication. The NC/IO board was not

able to receive the Ring communication packet.

SOLUTION

Confirmation of optical cable

NOTE

1875

Ring communication time out

DESCRIPTION

The Ring communication error was detected.

CAUSE

There is a possibility of disconnection, omission of the optical cable.

SOLUTION

Please confirm the state of the optical cable.

NOTE
