SUNFAR E300 SERIES
F3.7 Linear speed coefficient set Setting range
：
0.01 ~ 10.00
Set running linear speed and linear speed display data, or display other physical quantity which
is direct ratio with output freq.
Running linear speed (d-8) = F3.7 × output freq (d-0)
Set linear speed (d-9) = F3.7 × set freq (d-6)
F3.8 Monitor parameter selection Setting range
：
0 ~ 21
Confirm operation panel display content under state monitor mode.
Monitor parameter selects confirmation LED display content.
Display data corresponding physical quantity that can refer to parameter state monitor
parameter list for reference.
F3.9 Parameter check and modify right Setting range
：
0 ~ 9999
It is for obtaining checkout code of some inner parameter check and modify right.
F3.10 Parameter initialization Setting range
：
0 ~ 9
Modify parameter as manufacture setting.
0
：
No action
1
：
Standard initialization: (F0~F4 unit parameters except F0.0, F0.2, F3.14, all other
parameters return to manufacture set.)
2
：
Clear failure record
3
：
Complete initialization: (F0~F4 unit parameters except F3.14, all other parameters
return to manufacture set and clear failure record)
F3.11 Low-volt protection level Setting range
：
180 ~230V / 360 ~460V
It is used for confirming DC side allowable lower limit volt under inverter normal running. For
some low power line, it can decrease low-volt protection level properly to ensure inverter normal
running.
Note: If power line volt is too low, motor output torque will decrease.
For constant power load and torque load, it will increase inverter input current if too low power
line volt, so decrease inverter running reliability.
F3.12 Over-volt limit action level Setting range
：
350 ~400V / 700 ~800V
