JT550 Series Inverter Manual
F0.08 Digital frequency
If the frequency source is digital setting or terminal UP/DOWN, the value of this parameter is the
initial frequency of the inverter (digital setting).
F0.09 Rotation direction
0: Same direction
1: Reverse direction
You can change the rotation direction of the motor just by modifying this parameter without changing the
motor wiring. Modifying this parameter is equivalent to exchanging any two of the motor's U, V, W wires.
F0.10 Maximum frequency
When the frequency source is AI, pulse setting (X5), or multi-reference, 100% of the input corresponds
to the value of this parameter.
Source of frequency
F0.11
upper limit
It is used to set the source of the frequency upper limit, including digital setting (F0.12), AI,pulse
setting or communication setting. If the frequency upper limit is set by means of AI1,AI2, AI3, DI5 or
communication, the setting is similar to that of the main frequency source X.For details, see the description
of F0.03.
F0.12 Frequency upper limit
This parameter is used to set the frequency upper limit.
Frequency upper
F0.13
limit offset
If the source of the frequency upper limit is analog input or pulse setting, the final frequency upper
limit is obtained by adding the offset in this parameter to the frequency upper limit set in F0.11.
Frequency lower
F0.14
If the frequency reference is lower than the value of this parameter, the inverter can stop, run at the
frequency lower limit, or run at zero speed, determined by F4.14.
F0.15 Carrier frequency
It is used to adjust the carrier frequency of the inverter, helping to reduce the motor noise, avoiding the
resonance of the mechanical system, and reducing the leakage current to the earth and interference generated
by the inverter.
