How can the Altivar 58 drive be set to freewheel stop?
With ATV58 or Econoflex drives, freewheel stop is based on the status of a logic input. In the I-O menu (menu 5) set up a logic input to be freewheel stop (NST). When the input is at 0 state (when there is no voltage on the input), the drive will freewheel stop.
It is also possible to set the drive up to freewheel stop when the frequency goes below a preset value. In menu 3 (drc or drive menu) set Stt to NSt. Then set the FFt threshold in menu 2 (SEt or Adjust menu) to the desired frequency at which to begin freewheel stop.
See the keypad programming guide for more details.
