Table 4.8-11 Cont.
Synchronous motor 1
(iron loss factor)
Set “the iron loss described in
motor test report divided by
Motor rated capacity: p 02 *”.
Set 0%, if the iron loss is
unknown.
Fuji standard synchronous motor
(GNB2 series) constant
Synchronous motor 1
(overcurrent protection
level)
Set the demagnetization limit
current. Set to prevent
demagnetizing the motor. If it is
unknown, set approx. 200% of
motor rated current.
Fuji standard synchronous motor
(GNB2 series) constant
Machine design values
(Note) For the test run of the
motor, increase values so that
they are longer than your
machine design values.
If the specified time is short, the
inverter may not run the motor
properly.
Please refer to Table 4.4-1 Initial
value for each destination
Frequency limiter (upper
limit)
Acceleration time 1

FRN0115G2S-2G/FRN0060G2■
-4G or below: 6.00 (s)
FRN0146G2S-2G/FRN0075G2■
-4G or above: 20.00 (s)
Deceleration time 1
(Note)
(3) Performing tuning (synchronous motors)
Perform tuning in accordance with the "4.8.2 [ 3 ] Synchronous motor tuning method”.
If a filter other than the Fuji optional output filter (OFL-□□□-□A) is connected to the inverter's output
(secondary) circuit, the tuning result cannot be assured. When replacing the inverter connected with such
a filter, make a note of the old inverter’s settings for the primary resistance %R1, leakage reactance %X,
no-load current, and rated slip frequency, and specify those values to the new inverter’s function codes.
Vibration that may occur when the motor's coupling is elastic can be regarded as normal vibration due to
the output voltage pattern applied in tuning. The tuning does not always result in an error; however, run
the motor and check its running state.
