TD20 Series VFD
Remarks: Press both the PRG/ESC and the DATA/ENT can return to the second-level menu from the
third-level menu. The difference is: pressing DATA/ENT will save the set parameters into the control
panel, and then return to the second-level menu with shifting to the next function code automatically;
while pressing PRG/ESC will directly return to the second-level menu without saving the parameters,
and keep staying at the current function code.
Under the third-level menu, if the parameter has no flickering bit, it means the function code cannot be
modified. The possible reasons could be:
1) This function code is not modifiable parameter, such as actual detected parameter, operation records
and so on;
2) This function code is not modifiable in running state, but modifiable in stop state.
Example: Set function code P00.01 from 0 to 1.
All digits are blinking.
