6.Control parameters and status parameters of VFD
The control parameters of VFD can achieve the function such as startup, stop,setting operating frequency and so
on.Retrieving the status parameters of VFD can obtain the parameters such as operating frequency,output
current,output torque and so on.
1.Control parameter
The control parameters of VFD are shown in following table.
The main setting
frequency: In the common
operation mode, the
channel of main setting is
serial communication, it
tack effects if the bit8 of
control word 1 is set on.
Wether it saves or not
depends on the setting in
A2.03
Operation frequency setting
Digital closed loop setting
Takes effects after the
closed loop is enabled
Pulse closed loop setting
Analog outprut AO1 setting
Analog outprut AO2 setting
Digital output DO setting
Frequency Proportion
setting
Virtual terminal control
setting
Bit~bit6: X1~X7.
Corresponding to on state
of the bits in A6.24
Bit10~bit13:
Y1/Y2/RO1/RO2, They are
enabled when
A6.14~A6.17=17
Set the acceleration time
Set the deceleration time
Note:
(1)When read control parameters,it will return the value which is rewrote in the previous communication.
(2)In control parameters,the preset value,range of input/output setting value and decimal point scaling should
refer to the corresponding function code.
