Vector control without PG
Refers to the open-loop vector control for high-performance control applications
typically , only one inverter to drive a motor.
1:
Vector control with PG
Refers to the closed-loop vector control, motor encoder client must be installed , the
drive must be matching with the same type of PG encoder card . Suitable for high-
precision speed control or torque control . An inverter can drive only one motor.
2:V/F control
Suitable for less precision control applications, such as fan and pump loads . Can be
used for an inverter drives several motors occasions.
Note: Vector control mode , the drive capacity and the level of non- motor capacity
difference is too large , the drive motor can power level than the big two or a small one ,
or it may result in performance degradation control , or the drive system does not work
properly .
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
320.00Hz.
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.
