Select the input channel of the main frequency of the inverter
。
0: Digital setting (no memory is lost), the main frequency is set by parameter P0-08.
The set frequency value of the inverter can be modified by the ▲ and ▼ keys (terminal
UP/DOWN) of the keyboard.
When the inverter is powered off and powered up again, the set frequency is restored to
the set value of parameter P0-08.
1: Digital setting (power-down memory), the main frequency is set by parameter P0-08.
The set frequency value of the inverter can be modified by the ▲ and ▼ keys (terminal
UP/DOWN) of the keyboard.
When the inverter is powered off and powered up again, the set frequency memory is the
set frequency at the last power-down time.
(P0-23 is the setting frequency stop memory selection. When the inverter stops, the
frequency change amount is memorized or cleared. P0-23 is related to the shutdown,
not related to the power-down memory, so pay attention to the application.)
2: Analog AI1 setting, the main frequency is determined by inputting 0V~10V from AI1
terminal.
3: Analog AI2 setting, the main frequency is determined by AI2 input 0V ~ 10V or 4mA ~
20mA
Control board J2 jumper selects whether AI2 is voltage input U or current input I (20mA
corresponds to 10V)
The input voltage value of AI1 and AI2 and the corresponding relationship with the target
frequency can be set by P4-13~27.
4: Panel potentiometer setting, the main frequency is set by the panel potentiometer.
5: The main frequency is given by the terminal pulse signal. The pulse signal
specifications are: voltage range 9V ~ 30V, frequency range 0kHz ~ 100kHz. The
pulse signal can only be input from terminal X6. (See P4-28~P4-31)
6: Multi-segment command, the main frequency can be composed of four multi-segment
terminals with different state combinations corresponding to 16 kinds of set frequency
values.
Set PC group function code corresponding to 16 multi-segment instructions, multi-segment
command terminal function is set in P4 group
7: The simple PLC main frequency is given by the PLC, and the PLC running frequency
and running time are set in the PC group.
8: PID, the main frequency is given by the output controlled by the process PID. Generally
used for closed-loop control in the field, such as constant pressure closed-loop control,
constant tension closed-loop control, etc., it is necessary to set the PA group PID
function parameters.
9: Communication given (optional), the main frequency is given by the host computer
through communication.
