Function Parameters - TECHTOP TD20 Series Product Manual

TD20 Series VFD

5 Function Parameters

The function parameters of TD20 series VFDs have been divided into 30 groups (P00–P29) according to
the function, of which P18–P28 are reserved. Each function group contains certain function codes
applying 3-level menus. For example, "P08.08" means the eighth function code in the P8 group function,
P29 group is factory reserved, and users are forbidden to access these parameters.
For the convenience of function codes setting, the function group number corresponds to the first level
menu, the function code corresponds to the second level menu and the function code corresponds to the
third level menu.
1. Below is the instruction of the function lists:
The first column "Function code": codes of function parameter group and parameters;
The second column "Name": full name of function parameters;
The third column "Detailed illustration of parameters": Detailed illustration of the function parameters
The fourth column "Default value": the original factory set value of the function parameter;
The fifth column "Modify": the modifying character of function codes (the parameters can be modified
or not and the modifying conditions), below is the instruction:
"○": means the set value of the parameter can be modified on stop and running state;
"◎": means the set value of the parameter can not be modified on the running state;
"●": means the value of the parameter is the real detection value which can not be modified.

Detailed instruction of parameters
0: SVC 0
.No need to install encoders. Suitable in applications
which need low frequency, big torque for high accuracy
of rotating speed and torque control. Relative to mode 1,
it is more suitable for the applications which need small
power.
1: SVC 1
1 is suitable in high performance cases with the
advantage of high accuracy of rotating speed and
torque. It does not need to install pulse encoder.
2: SVPWM control
2 is suitable in applications which do not need high
control accuracy, such as the load of fan and pump. One
VFD can drive multiple motors.
Select the run command channel of the VFD.
The control command of the VFD includes: start, stop,
forward/reverse rotating, jogging and fault reset.
0: Keypad running command channel
