Function Parameters 9-25
AC10 Inverter
9.3.3 Analog input monitoring
The value of analog is displayed by 0~4095.
0:Output true
1:Output false
As an example of DO1 output simulation, when inverter is in the stop status and enter F336,
press the UP key, the DO1 terminal is valid. Release the UP key, DO1 remains valid status.
After quitting F336, DO1 will revert to initial output status.
When inverter is in the stop status, and enter F338, press the UP key, the output analog will
increase, and when press the DOWN key, the output analog will decrease. After quitting the
parameters, AO1 will revert to initial output status.
F340 Selection of
terminal negative logic
0: None
1: DI1 negative logic
2: DI2 negative logic
4: DI3 negative logic
8: DI4 negative logic
16: DI5 negative logic
32: DI6 negative logic
64: DI6 negative logic
128: DI8 negative logic
For example if user wants to set DI1 and DI4 to negative logic, set F340=1+8=9
9.4 Analog Input and Output
AC10 series inverters have 2 analog input channels and 2 analog output channels.
F400 Lower limit of AI1 channel input (V)
F401 Corresponding setting for lower limit
of AI1 input
F402 Upper limit of AI1 channel input (V)
Setting range: F400~10.00
F403 Corresponding setting for upper limit
of AI1 input
F404 AI1 channel proportional gain K1
F405 AI1 filtering time constant (s)
When using analog inputs for speed control, sometimes it is necessary to scale the
relationship between the upper limit and lower limit of the value input analog, analog changes
and the output frequency, to achieve a satisfactory speed control effect.
The upper and lower limit of analog input are set by F400 and F402.
