4.3 The Drive and Programming Modes
The 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 settings
cannot 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. When
the drive is in Programming Mode, the “AUTO” and “HAND” keys are ignored.
n Drive Mode Details
The 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 occurred
n Programming Mode Details
The 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 Values
This example explains changing C1-02 (Deceleration Time 1) from 30.0 seconds (default) to 20.0 seconds.
