Chapter 5 Troubleshooting

5-4

Revision July 2008, EG03, SW V1.06

5.5 Over Heat (OH)

AC motor drive overheats

Heat sink overheats

Check if temperature of heat sink
is greater than 90

Yes

Reduce load

Temperature detection malfunctions.
Please contact DELTA.

If cooling fan functions normally

Change cooling fan

Check if cooling fan is jammed

Remove

obstruction

Check if surrounding temperature

is within specification

Adjust surrounding temperature
to specification

Maybe AC motor drive has malfunction or
misoperation due to noise. Please contact
DELTA.

Is load too large

5.6 Overload

OL1/ OL2

Reduce load or increase the power of AC motor drive

Check for correct settings at
Pr. 06-06 and 06-07

Yes

Modify setting

Is load too large

Maybe AC motor drive has malfunction
or misoperation due to noise.
