Can I use an AC drive on a servo motor?-

If you are looking to use a standard, plain AC variable frequency drive for a servo I suggest you will be out of luck. Servo motors typically require a different type of output – not a V/Hz or even vector type output PWM output waveform. Before you buy an AC drive said to be suited for servo motor, you might want to get that in writing and find someone that will stand behind the claim. If there is a cost savings to using an AC VFD drive to run your servo motor you may want to use the extra cash to get a factory technician to do a startup […]

How to select the AC drives cables.

In order to better understand the variables involved with the cables that are a key part of any AC drive system and to formulate a useful guide to cable selection, the most commonly recommended cables for AC drive applications have been studied by Iacdrive, in both a lab and working application. Some wiring methods were not examined, however, such as THHN building wire in conduit, since their use has been shown to have detrimental effects, as outlined in other studies. An exception to this exclusion was the use of PVC-Nylon insulated, PVC jacketed tray cables. These cables are the most commonly-installed type of industrial control cable, and though they are often misapplied for use in AC drives applications, they were included in the tests for purposes of comparison. The PVC-Nylon designs (PVC-Nylon/PVC Type TC and PVC-Nylon/PVC Foil Shield Type TC) were evaluated in both unshielded and foil shielded versions. […]
