3.8. Motor troubleshooting

Upon occurrence of an error, the '7-segment LED' blinks to display the alarm status and

the alarm code or bit is output. At that time, take appropriate measures referring to the

following table.

Table 3-1. Motor Troubleshooting

7-segment

LED

Alarm Name Operating Status Problem Solution

Comes on only by

turning on the control

power.

y Faulty PC board.

y Replace the

Servo Amplifier

Comes on with "start

ready complete" after

turning on the main

power supply.

y Faulty PC board.

y Replace the

Servo Amplifier

Comes on with "Servo

Power

element error

(over-

current)

Comes on with the

motor starts or stops

y Improper combination of

motor and amplifier.

y Select another

motor type.

Comes on only by

turning on the control

power.

y Faulty PC board.

y Replace the

Servo Amplifier

Comes on while the

motor is in operation.

with no torque. The

LED comes on after

the motor is operated

for a while.

y Improper wiring of the

motor power line (U, V,

W).

y Broken wire in a phase

of the motor power line.

y Improper combination of

motor and amplifier.

wiring.

y Review the

combination.

Over-load

Comes on if the motor

is in operation under

rated torque.

y Faulty PC board.

y Replace the

Servo Amplifier

Comes on only by

turning on the control

power.

y Faulty PC board.

y Replace the

Servo Amplifier

Comes on after a little

while since the main

power supply is turned

on.

y Input supply voltage is

too high.

y Input supply voltage

waveform is distorted.

y Lower the

supply voltage

below the

specification.

Over-voltage

Comes on while the

motor is in operation.

y The load inertia is too

large

y Reduce the

load inertia

below the

specification.

supply voltage

to the

specification.

Main power

supply drop

Comes on after the

main power is turned

on.

y The rectifier or the fuse

is blown.

y Replace the

Servo Amplifier.
