I am in need of a C++ library of OPC function calls. I also need example code. I need to transfer data using OPC between 2 PC's via Ethernet. Does anyone have any idea as to where I can purchase the library, with examples and good documentation? Thanks, rdrago
What is the point of installing VSD's on conveyor motors that will run only at 60HZ?
Would a "soft starter" be a better choice considering how VSD's can potentially damage non-inverter equipped motors even with the addition of dv/dt filters? Also, VSD's generate harmonics on the...
A 20 HP, 3 phase, 480 volt motor is connected to a motor drive. The measured current (Fluke 43B) at the input to the drive is as follows:
Phase 1- 2.3A
Phase 2- 5.4A
Phase 3- 5.3A
Does anyone have any idea why the Phase 1 current at the input to the drive is so low? The motor and...
How do I measure power in a 3 phase electric motor? I am trying to justify the installation of a drive on a motor based on the power savings obtained through the use of a drive. The motor is running a fan load. The problem lies in the fact that the power factor at different motor speeds...
