5.5 Quick Start Parameter Descriptions
Brief descriptions of the Quick Start parameters are provided here for your reference.
Full descriptions of the parameters are provided in the software I/M. These
descriptions are listed in the order that they are displayed during the Quick Start
procedure for vector-regulated drives. For V/Hz regulated drives, fewer parameters
are displayed and the order is slightly different.
For V/Hz control, the drive provides open-loop volts per hertz regulation, which is
appropriate for general purpose applications
For vector control, you may select either flux vector control (FVC) or sensorless vector
control (SVC).
Flux vector control uses the actual encoder value for speed feedback and, therefore,
requires an encoder mounted to the motor and connected to the drive. You program
the drive for FVC by first selecting VECTOR in the REGULATION TYPE parameter
(P.048) and then selecting the PPR value of the encoder in the ENCODER PPR
parameter (U.001).
Sensorless vector control is an extension of the FVC regulator. It provides
performance close to FVC without using an encoder. Control is based on estimated
speed feedback. You program the drive for SVC by first selecting VECTOR in the
REGULATION TYPE parameter (P.048) and then selecting SENSORLESS in the
ENCODER PPR parameter (U.001).
Switching from one regulator type to the other takes approximately ten seconds.
Changing this parameter restores the default values of all General Parameters (P.---)
except for REGULATION TYPE and DEFAULTS TYPE (P.049).

ATTENTION: The incorrect programming of Quick Start parameters
can cause an overspeed condition. These parameters must be
programmed by a qualified person who understands the significance of
programming them accurately. Verify that the values of these
parameters are programmed accurately for your application. Failure to
observe this precaution could result in bodily injury.
