Selection of inverter frequency command input channels. There are 9 main frequency
setting channels:
0: Keyboard
Accomplish keyboard frequency setting bymeans ofmodifying the value of function code
F0.07” Keyboard frequency setting”
1: AVI
2: ACI
3: AVI+ACI
Thismeans that the frequency is set up through analog input terminals. ACD series inverter
provides 2 analog input channel. VI is 0-10V voltage input mode, while CI can be 0-10V input or
0 (4)-20mAinput.
The 100.0%setting of analog input is corresponding to the maximum frequency (Function
Code F0.04), and -100.0%is corresponding to maximumreverse frequency (Function Code
F0.04).
4:Multi-speed operation
The inverter is operated in the mode of multi-speed once this frequency settingmode is
chosen. It isneeded to set up the parameters of F2 Group and F4 Group “Multi-speed control
group” to determine the coincidence relation between given percentage and given frequency.
5: PIDcontrol
Selection of this parametermeans that the operation mode of inverter is PID controlmode.In
this case, it is required to set up F4 Group “PID control group” . The operation frequency of
inverter is the frequency value which PID gives. Please refer to the description of F4 Group “PID
