Selection and handling of output terminal AO1
•
The current/voltage output of terminal AO1 is set by both the toggle switch SW3 on control board and 02-45. When
the user need to select the output type of terminal AO1, please turn the toggle switch SW3 to the corresponding
type at first and then set the value of 02-45.
•
The output of the terminal AO1 are shown as follows:
Figure 1. AO1-GND output 0~10V voltage Figure 2. AO1-GND output 0~20mA current
Figure 3. AO1-GND output 4~20mA current
•
For the difference on the components, header needs to be calibrated, the voltage/current calibration procedures of
AO1 terminal:
1. Set the toggle switch SW3 to 0~10V/0~20mA, then set 02-45 at 0 or 2.
2. Insert an electric meter with a full graduation of 10V/20mA across terminal AO1 and terminal 5. Set 02-04 at 0.,
02-51 at 60Hz.
3. Set 01-11 at 0. Start the motor. Fix the output frequency of the inverter to 0 Hz.
4. Press
>
to adjust the value of 02-47. The screen will display the accumulated output bias voltage of AO1.
Press
WRITE
for more than 1 second, and the pointer will move upward. Press to reduce the value of 02-47, and the
screen will display the progressively decreased output bias voltage of AO1. Press
>
for more than 1second, and
the pointer will move downward. When the pointer is adjusted to 0, the calibration of AO1 output bias voltage is
completed.
5. Adjust and fix the output frequency of the inverter at 60 Hz.
6. Read the set value of 02-46, and the screen will display the current output gain of AO1.
7. Press
>
or
>
to adjust the value of 02-46. Press
WRITE
for more than 1 second, and the pointer will move
upward or downward. When the pointer moves to the full-scale position, the calibration is completed.

When selecting the output signal of terminal AO1, please pay attention to the switch of SW3. If 4~20mA output current is
selected, please switch SW3 to 0~20mA.
