When an option card is installed onto an Altivar 58 is it necessary to repeat the entire procedure for setting the configuration for small motors used in Demo units?

Yes. Installing an option card causes the drive to reset to factory defaults. This will require the settings to be entered again. This includes enabling small motor operation and disabling output phase loss fault.

* Note: Altivar 58 drives using firmware revision less than 4.1 IE25 (Fall 2001) require special settings to be entered into the drive to allow small motor operation for Demo units. For assistance contact Drive Products Support at 888-SQUARED or E-mail
