Fault alarm reason

FN function cannot be executed

when servo is ON

Fault alarm check

FN function cannot be executed

when servo is ON

disposal measures

Perform FN function with SV-OFF

A.910: Overload warning

Fault alarm reason

Fault alarm check

disposal measures

overload warning

Improper setting of control system

parameters

Motor wiring error

Can be monitored via d13.oL. in

monitor mode

1. Whether the mechanical system

is installed

2. Acceleration setting constant is

too fast

3. Whether the gain parameters are

set correctly

Check U, V, W wiring

Increase P00-51 (overload warning

value) appropriately

1. Adjust the gain of control loop

2. Increase the acceleration and

deceleration time

correct wiring

A.911: Vibration Warning

Fault alarm reason

Abnormal vibration of motor

speed detected

The value of the moment of

inertia ratio (P01-04) is larger than

the actual value or varies greatly

Fault alarm check

Confirm the abnormal sound of the

motor and the speed and torque

waveform during operation.

Confirm the load moment of inertia

ratio

disposal measures

Reduce the motor speed.

Or reduce the speed loop gain

(P02-10)

Set the appropriate ratio of moment

of inertia (P01-04)

P01-10 can be set to turn off the

alarm

A.912: Abnormal Control Board Temperature

Fault alarm reason

Abnormal temperature of control

board

Fault alarm check

Check Drive Temperature

Does the cooling fan work properly

disposal measures

improve heat dissipation condition

of that drive

Drive temperature still alarms

under normal conditions, replace

the drive

A.913: Abnormal Drive Temperature
