Revision May 2008, ME14, SW V3.04

 

5.2 Ground Fault 

 

 

GFF

Ground fault

No

Yes

Is output circuit(cable or 

motor) of AC motor drive 

grounded?

Remove ground fault

Maybe AC motor drive  has 

malfunction or misoperation

due to noise. Please 

contact DELTA.

 

5.3 Over Voltage (OV) 

 

 

 

Over voltage

Yes

No

Yes

No

No

No

Is voltage within 
specification

Reduce voltage to
be within spec.

Has over-voltage occurred without load

Maybe AC motor drive
has malfunction or  

misoperation due to
noise. Please contact
with DELTA.

Yes

Yes

Yes

Yes

Yes

Yes

No

No

No

No

No

When OV occurs, check if the 

voltage of DC BUS is greater
than protection value

Dose OV occur when 

sudden acceleration
stops

Increase
deceleration
time

Increase setting time

Increase

acceleration

time

Reduce moment 
of inertia

Reduce moment of load  inertia

Use braking unit or DC braking

Need to check control method. Please contact DELTA.

Need to consider using

braking unit  or
