0:Vector control W/O PG
Refers to the open-loop vector control for high-performance control applications
typically ,only one inverter to drive a motor.
2:V/F control
Suitable for less precision control applications, such as fan and pump loads .One inverter
can
be used for several motors at the same time.
Note:When vector control mode , the frequency inverter and motor capacity can not be
vary widely.The AC drive’s power can be bigger than motor’s power two degree or smaller than
motor’s power one degree.If not, it may result in not very good performancecontrol ,or the drive
system does not work normally .

When "Digital Setting" or "Terminal UP/DOWN " is selected as frequency source, the
parameter value is the initial value of the inverter frequency digital setting.

This parameter is used to determine the resolution of all related frequency parameters.
When the frequency resolution is 0.1Hz, PI9000 maximum output frequency can reach
3200Hz, when the frequency resolution is 0.01Hz , PI9000 maximum output frequency is
300.00Hz.
Note: when modifying the function parameters, the number of decimal places of all related
frequency parameters will change displayed, the frequency value will change accordingly.
