Zero-Speed Mode; V/F Curve Selection - Delta C2000 series User Manual

Zero-speed Mode

Settings
 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, FOC Sensorless,
and SVC modes. It executes zero-speed operation in VFPG and FOCPG mode.
 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, VFPG, SVC, FOC Sensorless and FOCPG modes.
