：
External analog signal AI2
（
0~10V or 0-20mA
）
,use S1(AI2) dial switch to determine
voltage/current signal
4
：
up/down 1 setting
Present frequency is set by terminal defined by up/down function. Frequency setting is held
when the drive stops.
5
：
up/down 2 setting
Present frequency is set by terminal defined by up/down function. Frequency setting is the
data of P0.11 when the drive stops.
6
：
Multi Frequency
You need to set relevant parameter of the P6 I/O and P2 ,When choose multi frequency
operational mode
7
：
PID
8
：
RS485 setting
Frequency setting is set by host computer via RS485 serial communication command.
9
：
Program running
When inverter begins running,Need to set P9 parameter.
P0.04
Main Frequency gain
Setting arrange
：
0.000~9.999
The main frequency is the product of the setting frequency selected by parameter P0.03 and
this gain.
P0.05
Zero frequency source of
multi-speed mode
