The drive powers up in Drive mode. In this mode the drive can be controlled normally
from Auto or Hand control place. In the Drive mode the Bypass running relay output
signal is off and the drive's output contactor is energized by closing the relay RO2 on

the drive is in Drive mode.
The Drive mode can be entered from the Bypass mode by pressing the Hand/Auto
button and selecting either Hand or Auto behind the Drive menu.
Mode of operation is the same in both the conventional and electronic bypasses.
However, there are different methods for determining the modes. The procedures in
this section are used to change operational modes.

● This mode is used when the drive is to have control of the motor, and the drive is
being used with an automation system.
