2: Analog AI2 setting (corresponding terminal AI2)
3: Analog AI3 setting (corresponding terminal AI3)
Set the frequency by analog input terminals. TD20
series VFDs provide 3 channels analog input terminals
as the standard configuration, of which AI1 is adjusting
through analog potentiometer, while AI2 is the
voltage/current option (0–10V/0–20mA) which can be
shifted by jumpers; while AI3 is voltage input
(-10V–+10V).
Note: when analog AI2 select 0–20mA input, the
corresponding voltage of 20mA is 10V.
100.0% of the analog input setting corresponds to the
maximum frequency (function code P00.03) in forward
direction and -100.0% corresponds to the maximum
frequency in reverse direction (function code P00.03)
4: High-speed pulse HDI setting
The frequency is set by high-speed pulse terminals.
TD20 series VFDs provide 1 high speed pulse input as
the standard configuration. The pulse frequency range is
0.00–50.00kHz.
100.0% of the high speed pulse input setting
corresponds to the maximum frequency in forward
direction (function code P00.03) and -100.0%
corresponds to the maximum frequency in reverse
direction (function code P00.03).
Note: The pulse setting can only be input by
multi-function terminals HDI. Set P05.00 (HDI input
selection) to high speed pulse input, and set P05.49
(HDI high speed pulse input function selection) to
frequency setting input.
5: Simple PLC program setting
The VFD runs at simple PLC program mode when
P00.06=5 or P00.07=5. Set P10 (simple PLC and
multi-step speed control) to select the running frequency
running direction, ACC/DEC time and the keeping time
of corresponding stage. See the function description of
P10 for detailed information.
