Description
Run key
This key is used to operate on the VFD in key
operation mode
Stop/
Reset key
This key is used to stop in running state and it is
limited by function code P07.04
This key is used to reset all control modes in the
fault alarm state
Quick key
The function of this key is confirmed by function
code P07.02.

Keypad
port
External keypad port. When the external keypad with the function of parameter
copying is valid, the local keypad LED is off; When the external keypad without
the function of parameter copying is valid, the local and external keypad LEDs are
on.
Note:
Only the external keypad which has the function of parameters copy owns
the function of parameters copy, other keypads do not have.

Analog
potentio
meter
AI1,
When the external common keypad (without the function of parameter copy)
is valid, the difference between the local keypad AI1 and the external keypad AI1
is:
when the external keypad AI1 is set to the Min. value, the local keypad AI1 will be
valid and P17.19 will be the voltage of the local keypad AI1; otherwise, the
external keypad AI1 will be valid and P17.19 will be the voltage of the external
keypad AI1.
Note
: If the external keypad AI1 is frequency reference source, adjust the local
potentiometer AI1 to 0V/0mA before starting the VFD.
4.2 Keypad displaying
The keypad displaying state of TD20 series VFDs is divided into stopping state parameter, running state
parameter, function code parameter editing state and fault alarm state and so on.
4.2.1 Displayed state of stopping parameter
When the VFD is in the stopping state, the keypad will display stopping parameters which is shown in
figure 4-2.
In the stopping state, various kinds of parameters can be displayed. Select the parameters to be
displayed or not by P07.07. See the instructions of P07.07 for the detailed definition of each bit.
In the stopping state, there are 14 stopping parameters can be selected to be displayed or not. They are:
set frequency, bus voltage, input terminals state, output terminals state, PID given, PID feedback, torque
set value, AI1, AI2, AI3, HDI, PLC and the current stage of multi-step speeds, pulse counting value,
length value. P07.07 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.
