)unction Code Parameter Name Setting Range Default
)0-08 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).
)unction Code Parameter Name Setting Range Default
)0-09 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.
Note
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.
)unction Code Parameter Name Setting Range Default
)0-10 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

After the value of )0-22 is modi¿ed, the frequency resolution of all frequency related function
codes change accordingly.
