0: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:Reserved
2:V/F control
Suitable for less precision control applications, such as fan and pump loads. Can be used for
an inverter drives several m`otors occasions.
Note: Vector control mode, the drive capacity and the level of motor capacity difference
can’t be too large, the drive motor can power level than the big two or a small one, otherwise it
may result in degradation of the control performance or the drive system does not work properly.

Select inverter master reference frequency input channels. There are 10 master reference
frequency channels in all:
8:PV setting/PID control setting
(1)PV setting, Solar pump functions is effective when E0 group of Solar pump special group
select 1 or 2, It’s belong to PID control setting if not setting E0.00=1 or 2.
(2) Select process PID control output as the operating frequency. Generally it is used for
closed-loop control, such as constant pressure closed-loop control, constant tension closed-
loop control, solar pump dedicated and other occasions.
Select PID as the frequency source, you need to set E2 group "PID function"parameters.
