Zero-speed Mode
Factory Setting: 0
Settings 0: Output waiting
1: Zero-speed operation
2: Fmin (Refer to Pr.01-07, 01-41)
When the frequency is less than Fmin (Pr.01-07 or Pr.01-41), it will operate by this parameter.
When it is set to 0, the AC motor drive will be in waiting mode without voltage output from
terminals U/V/W.
When setting 1, it will execute DC brake by Vmin(Pr.01-08 and Pr.01-42) in V/f, and SVC modes.
When it is set to 2, the AC motor drive will run by Fmin (Pr.01-07, Pr.01-41) and Vmin (Pr.01-08,
Pr.01-42) in V/F, SVC modes.
