2) V/f control
On acceleration.
On deceleration.
At constant speed.
Is power supply voltage within specification?
Does overvoltage occur on sudden removal of load?
Decrease power
supply voltage lower
than maximum
specification.
Inverter fault or
malfunction due to
noise is suspected.
Contact FUJI.
NO
Does abrupt
acceleration/
deceleration
activate
protection?
Can you specify longer deceleration time
(function code F08, C47, C57 or C67)?
NO
Is DC link circuit voltage in main circuit higher than protection
level on activation?
Can you specify longer
acceleration time
(function code F07, C46,
C56 or C66)?
Can you specify smaller moment of inertia of load?
Are braking device or DC braking function
(function code F20 to F22) used?
You should review braking method.
Contact FUJI.
Reduce moment of
inertia of load.
YES
Consider
application of
braking device or
DC braking
function.
NO

Specify longer
time.
