TD20 Series VFD
Keypad Operation Procedure
-21-
4.1.2 Displayed state of running parameters
After the VFD receives valid running commands, the VFD will enter into the running state and the keypad
will display the running parameters. RUN/TUNE LED on the keypad is on, while the FWD/REV is
determined by the current running direction which is shown as figure 4-2.
In the running state, there are 24 parameters can be selected to be displayed or not. They are: running
frequency, set frequency, bus voltage, output voltage, output torque, PID given, PID feedback, input
terminals state, output terminals state, torque set value, length value, PLC and the current stage of
multi-step speeds, pulse counting value, AI1, AI2, AI3, HDI, percentage of motor overload, percentage of
VFD overload, ramp given value, linear speed, AC input current. P07.05 and P07.06 can select the
parameter to be displayed or not by bit and
》
/SHIFT can shift the parameters from left to right,
QUICK/JOG (P07.02=2) can shift the parameters from right to left.
4.1.3 Displayed state of fault
If the VFD detects the fault signal, it will enter into the fault pre-alarm displaying state. The keypad will
display the fault code by flicking. The TRIP LED on the keypad is on, and the fault reset can be operated
by the STOP/RST on the keypad, control terminals or communication commands.
4.1.4 Displayed state of function codes editing
In the state of stopping, running or fault, press PRG/ESC to enter into the editing state (if there is a
password, see P07.00 ).The editing state is displayed on two classes of menu, and the order is: function
code group/function code number
→
function code parameter, press DATA/ENT into the displayed state
of function parameter. On this state, press DATA/ENT to save the parameters or press PRG/ESC to
escape.

4.3 Keypad operation
Operate the VFD via operation panel. See the detailed structure description of function codes in the brief
diagram of function codes.
4.3.1 How to modify the function codes of the VFD
The VFD has three levels menu, which are:
1. Group number of function code (first-level menu)
2. Tab of function code (second-level menu)
3. Set value of function code (third-level menu)
