12.1-01-10
 
01-34 
Zero-Speed Mode 
 
 
   
 Default: 0 
 
 
Settings  0: Output waiting 
1: Zero-speed operation 
2: Minimum frequency (Refer to Pr.01-07 and Pr.01-41) 
 When the drive’s Frequency command is lower than Fmin (Pr.01-07 or 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 and FOCPG mode. 
  2: the AC motor drive runs using 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. 
 In V/F, VFPG, SVC and FOC sensorless modes: 
 
 In FOCPG mode, when Pr.01-34 is set to 2, the AC motor drive operates according to this 
setting. 
   
 
01-43 
V/F Curve Selection 
 
 
   
 Default: 0 
 
 
Settings  0: V/F curve determined by Pr.01-00–01-08 
1: V/F curve to the power of 1.5   
2: V/F curve to the power of 2 
3: 60 Hz, voltage saturation in 50 Hz 
4: 72 Hz, voltage saturation in 60 Hz 
5: 50 Hz, decrease gradually with cube   
6: 50 Hz, decrease gradually with square 
7: 60 Hz, decrease gradually with cube   
8: 60 Hz, decrease gradually with square 
9: 50 Hz, medium starting torque 
10: 50 Hz, high starting torque
