d0-27
Flying start Kp
Range: 0.00~655.35
Factory default: 0
d0-28
Flying start Ki
Range: 0.00~655.35
Factory default: 2.00
d0-27 and d0-28 are PI parameters for software-based flying start. Appropriate parameter
values should be set according to real application for a decent flying start.
Group d1 V/f Control Parameters of Motor
Set control parameters in Group d1 when motor is selected as current load motor on which V/f
control is performed.
d1-00
V/f curve setting
Range: 0 - 1
Factory default: 0
Set the relation between output voltage and output frequency of the drive when the motor is
under V/f control.
0: Linear V/f
Applies to general constant-torque load. When drive output frequency is 0, output voltage will
be 0, while when output frequency is rated frequency of motor, the output voltage would be
rated voltage of motor.
1: Broken line V/f (determined by d1-01 - d1-08)
Applies to spin drier, centrifuge, industrial washing machine and other special loads. When
drive output frequency is 0, output voltage will be 0, while when output frequency is rated
frequency of motor, the output voltage would be rated voltage of motor. What is different is
this pattern can set 4 inflection points by d1-01 - d1-08. See Fig. 6-30.
V0, V1, V2, V3 and f0, f1, f2 and f3 in the figure are voltage value and frequency value set by
parameters d1-01 - d1-08.
