Function Code Parameter Name Setting Range Default
F0-08 Preset frequency
0.00 to maximum frequency (valid when
frequency source is digital setting)
50 Hz
If the frequency source is digital setting or terminal UP/DOWN, the value of this parameter
is the initial frequency of the AC drive (digital setting).
Function Code Parameter Name Setting Range Default
F0-09 Rotation direction
0: Same direction
1: Reverse direction
0
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.
The motor will resume running in the original direction after parameter initialization. Do not use
this function in applications where changing the rotating direction of the motor is prohibited after
system commissioning is complete.
Function Code Parameter Name Setting Range Default
F0-10 Maximum frequency 50.00–320.00 Hz 50.00 Hz
When the frequency source is AI, pulse setting (DI5), or multi-reference, 100% of the input
corresponds to the value of this parameter.
The output frequency of the MD380 can reach up to 3200 Hz. To take both frequency
reference resolution and frequency input range into consideration, you can set the number
of decimal places for frequency reference in F0-22.
• If F0-22 is set to 1, the frequency reference resolution is 0.1 Hz. In this case, the
setting range of F0-10 is 50.0 to 3200.0 Hz.
• If F0-22 is set to 2, the frequency reference resolution is 0.01 Hz. In this case, the
setting range of F0-10 is 50.00 to 320.00 Hz.
After the value of F0-22 is modied, the frequency resolution of all frequency related function
codes change accordingly.
