F04 Base Speed
F05 Rated Voltage
F04 and F05 specify the base speed and voltage of the motor that the inverter drives.
■
Base speed (F04)
Set the rated speed of the motor. In the case of an induction motor, please set the synchronous speed
of the motor. If the speed command units are r/min (Speed Command Unit function C21 equals 0),
the value of F04 can be obtained from the following expression:
Where f
r
is the rated frequency of the motor, in Hz.
 Data setting range changes depending on the number of poles of motor etc. For details, refer to
section 2.2.
■
Rated voltage (F05)
Set the rated voltage printed on the motor’s nameplate.
Note that the inverter cannot output the voltage exceeding the inverter's input voltage.
- Data setting range: 80 to 240 (V) 200V series
: 160 to 500 (V) 400V series
F07, F08 Acceleration/Deceleration Time 1, 2
E10 to E17
(Acceleration/Deceleration Time 3 to 10)
F07 and F08 specify the acceleration and deceleration times in linear acceleration/deceleration zones
excluding S-curve zones. The acceleration/deceleration time is the time duration required for the
speed to increase linearly from 0.00 r/min to the rated speed (F03) or decrease from the rated speed
to 0.00 r/min, respectively.
- Data setting range: 0.00 to 99.9 (s)

Time
When the inverter runs by an analog speed command, the acceleration and deceleration
times specified by F07 and F08 apply. When speed profile is generated on the controller
with analog signal, please set F07 and F08 to 0.00 s. On the other hand, a small value on
F07 and F08 (0.01 s or similar) may help if speed generated by the controller is not good
enough (to achieve smoother operation).
Also in local mode, the acceleration and deceleration times specified by F07 and F08
apply.
