 When the drive's Frequency command is lower than Fmin (Pr.01-07 and Pr.01-41), the drive
operates according to this parameter.
 0: the AC motor drive is in waiting mode without voltage output from terminals U, V, W.
 1: the drive executes the DC brake by Vmin (Pr.01-08 and Pr.01-42) in V/F, FOC sensorless, and
SVC modes. And it executes zero-speed operation in VFPG mode.
 2: the AC motor drive runs using Fmin (Pr.01-07 and Pr.01-41) and Vmin (Pr.01-08 and Pr.01-42)
in V/F, VFPG, SVC and FOC sensorless modes.
In V/F, VFPG, SVC and FOC sensorless modes:
Pr.01-11 lower limit > Pr.01-07 Fmin
Pr.01-11 lower limit < Pr.01-07 Fmin
0: Output waiting
1: Zero-speed operation
2: Fmin (refer to Pr.01-07, Pr.01-41)
