<Setting>
• When P.54=0, if the output frequency of the inverter is the set value of P.55, a voltage of 10V is
output at terminal AM.
• When P.54=1, if the output current of the inverter is the set value of P.56, a voltage of 10V is output
at terminal AM.

• AM terminal checking steps:
1. Connect an electric meter whose full graduation is 10V between terminal A and terminal 5, and
set P.54 to 0, then please check the meter because of the difference of the accessory.
2. Set P.13 to 0, then start the motor, and fix the output frequency of the inverter at 0Hz.
3. Read the set value of P.190, then the screen will display the current AM output bias.
4. Press
, press
SET
and hold for 0.5s, the finger of the meter moves upwards, the AM output
bias will increase. Press
to change the value of P.190, press
SET
and hold for 0.5s, the
finger of the meter moves downwards, the AM output bias will decrease. When adjusting the
scale pointer position to 0 to complete the AM output bias correction work.
5. Adjust and fix the output frequency of the inverter at 60Hz.
6. Read the setting value of P.191, then the screen will display the current AM output gain.
7. Press
to adjust the AM output gain, press
SET
and hold for 0.5s, the finger of the
meter moves upwards and downwards. When the finger of the meter moves to full range, finish
the checking.
Note: If P.187=1, P.55 is in the range of 0~1000Hz.
