Excessive external load

Check external load

Reduce the load or replace the

high-power motor

E.511: Gantry shaft alarm

Fault alarm reason

Two-axis drives, P 00-39, have an

axis associated alarm set and one

axis alarm.

Two-axis drive, open gantry

function, one of the axis alarm

Fault alarm check

Check whether each axis gives an

alarm

Check whether each axis gives an

E.520: Vibration Alarm

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

E.521: Self-adjusting vibration alarm

Fault alarm reason

The motor vibrates greatly when

using the adjustment-free function

(factory setting)

Fault alarm check

Confirm the waveform of the motor

speed.

Motor vibration is high when

performing advanced auto tuning,

single parameter tuning, EasyFFT

Confirm the waveform of the motor

speed.

disposal measures

Decrease the load moment of

inertia ratio below the allowable

value, or increase the tuning value

of the adjustment free value setting

(Fn200), or decrease the gain value.

The processing method described

in the operation procedure for

implementing each function

E.620: Encoder Off Line

Fault alarm reason

Bus encoder communication

Fault alarm check

Check Encoder Wiring
