Hello ! In a simovert masterdrive of 800 KW we have replaced the original motor of 610kw, rated speed 747 rpm with another motor of 800 kW,rated speed 990 rpm. The motor is used in a fan application. The new motor does not go more than 688 rpm even the setpoint is higher and current has not reach nominal value of 810 A. The maximum point where motor is running is 688 rpm with 774 A. Attached full parameter list (old motor and new) Can someone help please ! Attachment217.19VS1.rar (203 Downloads) |

Hello ! Thank you for your reply ! I checked the parameters you mentioned and limits of current and torque are set right. The only thing i did not right during commissioning of the new motor is that i did not changed the value of the motor torque (reference torque). Normally the new motor have less torque than the old one. During drive operation i see r0007 = 100 %, i think this maybe is the cause that drive does not increase frequency of the motor. Sorry but i can not upload parameter set as .dnl so i am uploading in pdf. Attachmentparameter set.pdf (256 Downloads) |
