Function Code Parameter Name Setting Range Default
F8-13 Reverse control
0: Enabled
1: Disabled
0
It is used to set whether the AC drive allows reverse rotation. In the applications where
reverse rotation is prohibited, set this parameter to 1.
Function Code Parameter Name Setting Range Default
F8-14
Running mode when
frequency reference lower
than frequency lower limit
0: Run at frequency lower limit
1: Stop
2: Run at zero speed
0
It is used to set the AC drive running mode when the frequency reference is lower than the
frequency lower limit. The MD380 provides three running modes to satisfy requirements of
various applications.
Function Code Parameter Name Setting Range Default
F8-15 Droop control 0.00–10.00 Hz 0.00 Hz
This function is used for balancing the workload allocation when multiple motors are used
to drive the same load. The output frequency of the AC drives decreases as the load
increases. You can reduce the workload of the motor under load by decreasing the output
frequency for this motor, implementing workload balancing between multiple motors.
Function Code Parameter Name Setting Range Default
F8-16 Accumulative power-on time threshold 0–65000 h 0 h
If the accumulative power-on time (F7-13) reaches the value set in this parameter, the
