5. Bypass Applications
For many applications, the drive is integrated into a bypass or engineered package. This type of package
typically features an enclosure with contactors which allow the user to run the motor from line power
(bypass mode) or from the drive (drive mode). This package also provides the flexibility for interfacing
normally closed safety interlocks (firestat, freezestat, vibration sensors, etc.) which stop the drive if the
contacts open.
5.1 Typical Parameter Settings
Because of the widespread use of this type of application, the following parameter set-up table is provided
to aid in the start-up of such a drive.

command is used, Terminal S6 Select must be set as listed to stop the motor if the safety
opens.
