4. Parameter description
Parameter
terminal function is selected, a voltage of 10V is output at terminal FM/AM, when the FM
terminal function is selected, a pulse of 1440Hz is output at terminal FM/AM
•
AM terminal checking steps:
1. Connect an electric meter whose full graduation is 10V between terminal FM/AM and terminal 5,
and set P.64=0, P.54 = 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
, the finger of the meter moves upwards, the AM output bias displayed on the screen
increases. Press
, the finger of the meter moves downwards, the AM output bias displayed on
the screen decreases. When the finger of the meter moves to 0, press
and hold for 1.0s to
finish the emendation of AM output bias.
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, and the finger of the meter moves upwards and
downwards. When the finger of the meter moves to full range, press
and hold for 1.0s to
finish the checking.
•
FM terminal checking steps:
1. Connect an electric meter whose full graduation is 1mA between terminal FM/AM and terminal 5,
and set P.64=1, P.54 = 0, then please check the meter because of the difference of the accessory.
2. Start the motor, and fix the output frequency of the inverter at 0Hz.
3. When the motor steadily, read the set value of P.187, then the screen will display the FM
correction index at this time. Press
, the finger of the meter moves upwards, the FM correction
index displayed on the screen increases. Press
, the finger of the meter moves downwards, the
FM correction index displayed on the screen decreases. When the finger of the meter moves to 0,
press
and hold for 1.0s to finish the emendation of the FM output terminal revision.
Note: 1. Functions of FM and AM share the same terminal
，
if functions change (Value of P.64 changes)
meanwhile, SW1 on the control panel is switching
，
initial value is AM.
2. When the value of P.74 is not 0, the FM and AM is in vain.
