Checking method and

remedy of trouble

(22) Alarm

Motor Overheat

[This

alarm

occurs when the thermal protec-

tor which is installed in the motor exceeds
the temperature being set

Item

Cause

The motor cooling fan
defective.

The motor cooling systen

is dirty.

Check that the air in-

take portion of the

motor cooling fan is
clogged with foreign
matter or machine com-
ponents.

The motor is overloaded.

The motor built-in

thermal protector is
defective.

The following cable con-
nections are defective.

Motor

Amplifier

side

CON2 pin 3

OHS2 CON2 pin 2

Check

Visually check that the fan

motor normally rotates.

Visually or by touching the

cooling system, check the
degree of dirt.

Visually check the position

of the foreign matter or
components.

Check the load of the motor

using a load meter or the

load display in the status

display mode

(see Section

Check that the motor is fre-

quently started and stopped.

After stopping the motor and

turning the cooling fan to
fully cool the motor, check
that the motor leads

and

OHS2 is shortcircuited.

(When they are shortcircuited

the thermal protector is
normal.)

Check the wire breakage or

connector imperfect contact
using a circuit tester.

Remedy

Replace the motor cooling

fan with a new one.

(See Section 2.8.)

Clean the cooling system

using the factory utility
air or vacuum cleaner.

Remove the foreign matter.

Change the position of the

machine components.

Review the cutting condition

and tool.

the frequency of the

start and stop operations.

Shortcircuit

and OHS2

of CON2 on the amplifier

side as a temporary repair
and continue the operation.

(See Appendixes l-4 and

At a convenient time, re-

place the motor with a new
one.

Replace the signal cable

with a new one.

Repair the connector's

imperfect contact or re-

place the connector with a
new one.
