User manual POWTRAN PI7800

[. . . ] Foreword Thank you very much for purchasing PI7800PI7600 Family Frequency Inverters. This family is designed based on the experience of POWTRAN Company in the professional manufacture and sale of the products, and suitable for general-purpose machine, fan/pump drive, high frequency drive and heavy load machine. This User's Manual provides the users with the instructions on the installation, parameter setting, fault diagnosis, routine maintenance and necessary precautions. Please read the Manual carefully before the installation of the product in order to ensure that it can be correctly installed and operated.

It sets the protection to the load when the set regulated power supply out of the PID control (set, feedback signal invalid). If the max voltage that load voltage requires is 250V, input voltage 380V, and F12 250/380=66% Running mode Adjustment of the acc/dec time could adjust the frequency acc/dec time. Adjustment PID and F28, F29 could adjust the voltage raising time and voltage responding time. l 1 Stabilized voltage supply output voltage200V, maximum voltage<210V. l 2 Stabilized voltage supply frequency 400Hz. l 3 Frequency set mode is keypad set. 4 5 6 Wiring Output voltage set mode 0~10V.
