6-11

Possible Causes

What to Check and Suggested Measures

(4) Cyclic overload occurred. CHECK

Measure ripple wave of intermediate dc circuit voltage.

SUGGESTED ACTIONS

– If the ripple is large, raise the drive capacity

(5) 1-phase voltage was

supplied to the drive

instead of 3-phase

voltage.

CHECK

Check the drive type.

SUGGESTED ACTIONS

– Change the drive to one for 1-phase voltage input.

[5] OPL Output phase loss protection

Problem

Output phase loss occurred.

Possible Causes

What to Check and Suggested Measures

(1) Drive output wires are

broken

CHECK

Measure the output current.

SUGGESTED ACTIONS

– Replace the output wires.

(2) Open circuit in motor

windings

CHECK

Measure the output current.

SUGGESTED ACTIONS

– Replace the motor.

(3) The terminal screws for

drive output were not

tight enough.

CHECK

Check if any terminal screws have become loose.

SUGGESTED ACTIONS

– Tighten the terminal screws to the recommended torque.

(4) A 1-phase motor has

been connected

SUGGESTED ACTIONS

– 1-phase motors cannot be used. Note that the AF-300 Mini only drives 3-phase induction motors.

[6] OH1 Overheat protection for heat sink

Problem

Temperature around heat sink rose.

Possible Causes

What to Check and Suggested Measures

(1) Temperature around the

drive exceeded that of

drive specifications.

CHECK

Measure the temperature around the drive.

SUGGESTED ACTIONS

– Lower the temperature around the drive (e.g. improve control board ventilation).

– Reduce the load.

(2) Accumulated running

time of the cooling fan

exceeded the standard

period for replacement,

or the cooling fan

malfunctioned.

CHECK

Check the accumulated running time (E52 = 2). Refer to Chapter 3, Section 3.8 “Reading Maintenance

Information.”

SUGGESTED ACTIONS

– Replace the cooling fan.

CHECK

Visually check that the cooling fan rotates normally.

SUGGESTED ACTIONS

– Replace the cooling fan.

(3) Air vent is blocked.

CHECK

Check if there is sufficient clearance around the drive.

SUGGESTED ACTIONS

– Increase the clearance.

CHECK

Check if the heat sink is clogged.

SUGGESTED ACTIONS

– Clean the heat sink.
