4.3 The Drive and Programming ModesThe bypass controller has a Drive Mode to operate the motor and a Programming Mode to edit parameter settings..Drive Mode: In Drive Mode the user can operate the motor and observe U Monitor parameters. Certain parameter settingscannot be edited or changed when in Drive Mode.Programming Mode: In Programming Mode the user can edit and verify parameter settings and perform Auto-Tuning. Whenthe drive is in Programming Mode, the “AUTO” and “HAND” keys are ignored.n Drive Mode DetailsThe following actions are possible in the Drive Mode:• Run and stop the drive• Monitor the operation status of the drive (frequency reference, output frequency, output current, output voltage, etc.)• View information on an alarm• View a history of alarms that have occurredn Programming Mode DetailsThe following actions are possible in the Programming Mode:• Parameter Setting Mode: Access and edit all parameter settings.• Modified Constants: View a list of bypass parameters that have been changed from the default values.• Quick Setting Group: Access a list of commonly used parameters to simplify setup• Auto-Tuning Mode: Automatically calculate and set motor parameters to optimize drive performance.u Changing Parameter Settings or ValuesThis example explains changing C1-02 (Deceleration Time 1) from 30.0 seconds (default) to 20.0 seconds.Step Display/Result1.
