When the application situation has no electrical source, taking advantage of this
function makes motor speed down to zero in deceleration mode, meanwhile, the
inverter can restart in recovery time
5.3 Group F2 V/F Control Parameters
This group function is only for V/F control（F0-03＝2）, not for the vector control.
V/F control is applicable to the general loads such as fan and pump or the
applications where one inverter drives multiple motors or the inverter power is one
level lower or higher than the motor power
