Group F0: Basic Function
F0.00
1: G type (constant torque load)
2: P type (variable torque load e.g. Fan and pump)
F0.01
0: Sensorless flux vector control (SFVC)
It indicates open-loop vector control, and is applicable to high-performance control applications such as
machine tool, centrifuge, wire drawing machine and injection moulding machine. One inverter can operate
only one motor.
1: Closed-loop vector control (CLVC)
It is applicable to high-accuracy speed control or torque control applications such as high-speed paper
making machine, crane and elevator. One inverter can operate only one motor. An encoder must be installed
at the motor side, and a PG card matching the encoder must be installed at the inverter side.
2: Voltage/Frequency (V/F) control
It is applicable to applications with low load requirements or applications where one inverter operates
multiple motors, such as fan and pump.
F0.02
0: Operation panel control
Commands are given by pressing keys "RUN,STOP"on the operation panel.
1: Terminal control
Commands are given by means of multifunctional input terminals with
JOGF, and JOGR".
2: Communication control
Commands are given from host computer.
F0.03
0: Digital setting (non-retentive at power failure)
The initial value of the set frequency is the value of F0.08 (Preset frequency). You can change the set
frequency by pressing Λ、V on the operation panel (or using the UP/DOWN function of input terminals).
When the inverter is powered on again after power failure, the set frequency reverts to the value of
F0.08.
1: Digital setting (retentive at power failure)
Basic operations are the same as "0: Digital setting" .
The only difference is that when the inverter is powered on again after power failure, the set frequency
is the value memorized at the moment of the last power failure.
Note: The hidden parameters set down by F0.20 cleared or unclear 0, factory default is cleared down.
2: AI1 (0–10 V voltage input)
3: AI2 (0–10 V voltage input or 4–20 mA current input, determined by jumper )
4: AI3 (0–10 V voltage input)
The frequency is set by analog input.
5: Pulse setting (X5)
The frequency is set by X5 (high-speed pulse). The signal specification of pulse setting is 9–30 V
(voltage range) and 0–100 kHz (frequency range). The corresponding value100% of pulse setting
corresponds to the value of F0.10 (Maximum frequency).
6: Multi-reference
In multi-reference mode, combinations of different X terminal states correspond to different set
frequencies. The JT550 supports a maximum of 16 speeds implemented by 16 state combinations of four X
terminals (allocated with functions 12 to 15)in Group FC. The multiple references indicate percentages of the
value of F0.10(Maximum frequency).
