F03 Maximum frequency 1
•
This is the maximum frequency which is
output by the inverter of motor 1.
Setting range: 50 to 400 Hz
If a value larger than the rating of the driven
unit is set, the motor or machine may be
broken. Set a value suitable for the driven
unit.
F04
Base frequency 1
•
This is the maximum output frequency in the
constant torque zone of motor 1, that is, the
output frequency at the rated output voltage.
Set the rating of the motor.
Setting range: 25 to 400 Hz
Note) If the setting of base frequency 1 is
larger than the setting of maximum frequency
1, the output frequency is limited by the
maximum frequency and the output voltage
does not rise to the rated voltage.
F05
Rated voltage 1
•
This is the output voltage value at base
frequency 1 which is output to motor 1.
However, voltages exceeding the source
(input) voltage cannot be output.
Setting range: 0, 80 to 240 V for 200V class
0, 160 to 480 V for 400V class
A "0" setting stops the operation of the
voltage adjustment function. Therefore a
voltage proportional to the source voltage is
output.
Note) If the setting of rated voltage 1 is larger
than the setting of maximum output voltage 1,
the voltage is limited by the maximum output
voltage and it does not rise to the rated
voltage.
F06
Maximum voltage 1
•
This is the maximum value of the output
voltage of the inverter of motor 1. However,
voltages exceeding the source (input) voltage
cannot be output.
Setting range: 0, 80 to 240 V for 200V class
0, 160 to 480 V for 400V class
Selecting Functions
F07 Acceleration time 1
F08 Deceleration time 1
•
These are the acceleration time taken for the
output frequency to reach the maximum
frequency from the start, and the deceleration
time taken to stop from the maximum output
frequency.
Setting range: Acceleration time 1: 0.01 to
3600 s
Deceleration time 1: 0.01 to 3600 s
The number of significant digits of the
acceleration and deceleration time is three.
Therefore the uppermost three digits can be
set.
The acceleration time and deceleration time
are set based on the maximum frequency.
The relationship between the frequency
setting and the acceleration/deceleration time
is as shown below.
Set frequency<Maximum output frequency
The setting differs from the actual operation time.

frequency)
Note) If an excessively short acceleration or
deceleration time is set though the load torque
or moment of inertia of the load is large, the
torque limiter or stall prevention function is
activated. When these functions are activated,
the time becomes longer than the operation
time explained above.
