Description

Countermeasure

400

The servo motor has overheated.

(estimated value)

The motor operation condition may

be too severe.

Check the operation condition.

401

DRDY(Drive Ready signal) becomes 0.

The servo amplifier is not ready.

SVM1-4

SVM1-20

The cooling fins have

overheated.

(hardware detection)

The load on the motor may be too

high.

Re-examine the load conditions.

403

SVM1-40

SVM1-80

This alarm will not be

issued.

The regenerative discharge unit has

overheated.

This alarm is issued when the

average regenerative discharge

energy is too high (when the

acceleration/deceleration frequency

is too high, for example).

404

(1) When the separate regenerative discharge resistor is not used.

For the SVM1-4

and SVM1-20

, check whether the CXA20 connector

is short-circuited by using a dummy connector.

For the SVM1-40

and SVM1-80

, check whether the CXA20 and CZ6

connectors are short-circuited by using dummy connectors.

(2) The average regenerative discharge energy may be too high.

Decrease the acceleration/deceleration frequency.

(3) The separate regenerative discharge unit may not be connected

properly. Check the connection.

(4) The thermostat of the separate regenerative discharge unit may be

defective. Disconnect the separate regenerative discharge unit,

then check the thermostat. If the thermostat is open even through the

separate regenerative discharge unit is cool, replace the separate

regenerative discharge unit.

(5) The resistor of the separate regenerative discharge unit may be

defective. Disconnect the separate regenerative discharge unit,

then check the resistance. If it does not fall in the range of the

predetermined resistance "20%, replace the separate regenerative

discharge unit.

(6) If from (1) to (5) are not the cause of the alarm, replace the servo

amplifier unit.

Reference position return could not be

executed correctly.

Re-execute reference position

return.

405

If a value in the range of 4 to 96 is set for parameter No. 032 (CMR),

an alarm may be issued. In this case, prevent an alarm from being issued by

setting N405(bit4 of parameter No. 001) to "1".

Unexpected disturbance torque has

been detected.

409

(1) Investigate the mechanical cause of the unexpected disturbance torque,

for example collision.

(2) If no mechanical cause is found, check whether the tuning result about

estimated disturbance torque is correct.(No.093,No.094,No.115)

(3) If the estimated disturbance torque is tuned correctly, specify a larger

value of threshold for the unexpected disturbance torque.(No.096)
