This function code is to determine the inverter operating state when the set frequency is
less than the lower limit frequency.
0: Run at the lower limit frequency: means that the inverter runs at the lower limit
frequency when the operating frequency is less than the lower limit frequency.
1: Stop. In order to prevent motor operating at low speed for a long period of time, can use
this function to stop.
2: stand-by state. Inverter stops when the set frequency is less than the lower limit
frequency. When the set frequency is once again higher than or equal to the lower frequency
limit, the inverter automatically starts to run.
Note: For PID control mode, the stand-by state function is invalid.

0: NO restart. Indicate that after the power is down, the inverter does not automatically
restart if the power is back, until an operating command is input.
1: Permit restart. It indicates that if keypad control or remote communication control is
applied, when the power is back on, no matter whether operation command exists or not, the
inverter can automatically restart after the restart delay time (P1.16) is passed; If under
terminal control mode, only when the terminal control start is valid, the inverter can
automatically restart after the restart delay time (P1.16) is passed. If the power is down at
stand-by, the permit restart function is invalid.
Important: the user must chose the permit restart function with caution, otherwise,
it may cause serious consequences.
