[3] inverter parameters configuration The system take the semi-closed loop control mode according to the control demand, so the inverter parameters configuration contains two parts. One is the communication configuration setting, another is closed loop control PID parameters setting. Communication parameters Parameters codes Value Instructions 918 1~14 Inverter port's address 916 Sub index1 518 Pcd3 Inverter output frequency Sub index2 524 PCD4 Motor voltage Sub index3 520 PCD5 Motor current Sub index4 517 PCD6 feedback 903 PPO 4 Communicate format Closed loop control parameters Parameters codes Value Instructions 100 1 Speed closed loop 102、103、104、105、106 Set as the motor nameplate 307 29 Pulse feed back 414 0 Min value 415 1350 Rated rotary speed 416 RPM Set the rotary speed unit 203 0 Same to 414 204 1350 Same to 415 The parameters above are needed by the basic functions of the line. The other parameters, such as PID proportional coefficient, integration time, could be adjusted according to the actual circumstance, please take the VLT2800 inverter work book for more instructions.
