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 .One inverter can
be used for several motors at the same time.
Note:When vector control mode , the drive andmotor capacity can not be vary widely.The
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 .
F0.01 Keyboard set frequency
0.00Hz to F0.19(maximum frequency) 50.00Hz
★
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.
F0.02 Frequency command resolution
0.1Hz

★
0.01Hz
2
This parameter is used to determine the resolution of all related frequency parameters.
When the frequency resolution is 0.1Hz,
JI500
maximum output frequency can
reach 3200Hz, when the frequency resolution is 0.01Hz ,
JI500
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.

Select inverter master reference frequency input channels. There are 10 master reference
frequency channels in all:
0: Keyboard set frequency (F0.01, UP/DOWN can be modified, power-down without
memory)
Initial value for the set frequency is F0.01 "preset frequency" value. The set frequency
value of the inverter can be changed by using the ▲ key and ▼ key on the keyboard (or multi-
function input terminals UP, DOWN).
The Inverter powers down and then powers on again, the set frequency value will be
recovered as F0.01 "digital preset frequency value".
1: Keyboard set frequency (F0.01, UP/DOWN can be modified, power-down with memory)
Initial value for the set frequency is F0.01 "preset frequency" value. The set frequency
value of the inverter can be changed by using the ▲ key and ▼ key on the keyboard (or multi-
function input terminals UP, DOWN).
The Inverter powers down and then powers on again, the set frequency value is same as the
frequency of the last power-down
Please note that F0.09 is for "digital set frequency stop memory selection ”, F0.09 is used to
select SAVE or CLEAR frequency correction when the inverter stops Besides, F0.09 is not
related to the power-down memory but shutdown.
