Integrated ODM & OEM Solutions Provider for Industrial Frequency Inverters
1, Load feature
(1) PID function is required.
(2) There is a pressure sensor in the system.
(3) In theory, if the running frequency is H1, then Energy Saving = 1-(H1/50)3
2, Requests for frequency inverters (VFD)
(1) Soft start the motor, reduce the surge current.
(2) PID control should be stable and accurate.

4, Parameters setting list
No. | Function codes | Default | Setting value | Explanation |
1 | F00.01 | 0 | 1 | Start / stop by external signal (If necessary) |
2 | F00.06 | 0 | 8 | PID control |
3 | F10.00 | 0 | 0 | PID target value set by F9-01 |
4 | F10.01 | 50% | -- | Set suitable value depend on system |
5 | F09.50 ~ F09.52 | -- | -- | Set suitable dormancy and wake up parameters. |
5, Notices
(1) select a suitable pressure sensor, the calculation of Fb-01 as below if the pressure sensor measure range is 16bar (1.6Mpa), and the target pressure is 5bar (0.5Mpa), then F10.01=5/16*100%=31.3%.
(2) Maintenance regularly, pay attention to dust and humidity prevention.
