What Is The Default Password For An AC Tech SMVector VFD?

/in , , /by

All AC Tech SMVector drives come equipped with a default password to protect the drive from operators changing parameters without the programmers consent. Although this process can be confusing the first time you open your AC Tech SMVector VFD, or Variable Frequency Drive, it is easy to do once youve done it once.

Password protection is becoming more and more prominent in the world of Variable Frequency Drives and the SMVector illustrates this process right out of the box. The purpose of protection is to keep the program within the drive protected from outside modifications or to allow OEMs to protect their proprietary configurations when selling a machine.

Many customers also opt to purchase a EPM module for their SMVector drive to keep their configuration files backed up to a separate module, just in case of a drive failure or EPM program failure. Whatever the reason for accessing the parameters, the process of accessing the parameter menu is extremely easy.
