Using the keypad to select Bypass Mode:
When the Bypass button is pressed, the following options are shown to the user. Select the desired mode by using the
arrow keys and pressing the OK key.
The user can toggle between modes by pressing the Bypass button again. If Bypass button is pressed while the Drive
is running, the keypads will display “Bypass is not allowed”. The system must be stopped to allow a change from Drive to
Bypass mode. Likewise if the system is running in Bypass and the Bypass key is pressed the display will indicated “Motor
Running in Bypass” To change state back to Drive the system must be stopped. The keypad will display Bypass in the Status
display when in the Bypass mode and Ready or E-Energy when in the Drive mode
Using the digital input to select Bypass Mode:
If the digital input (Force Bypass) is used to select the Bypass mode, the Drive is set to the Bypass mode the next time
the unit is stopped. If the command is given while the unit is running in the Drive mode, there is no effect unit the stop
command is given and the Drive reaches zero speed. Once the Drive stops, the Bypass mode is active and the keypad will
display the Bypass mode. The Bypass and motor will start when a valid start command is received. Note that the Force
Bypass function is the factory default for Digital Input #6 P2.3.6.2 located at TB16 on the control module and is also factory
wired to the M1 Manual Bypass option if supplied.
Using the Fieldbus to select Bypass Mode:
The Fieldbus command works the same as the digital input.
Auto Bypass operation
The Drive can also be Bypassed automatically if certain faults occur. When the selected fault occurs, the Drive is first
stopped. Then, depending on the Automatic Reset parameter, the Drive is either Bypassed instantly or the fault is first tried
to reset. If the reset fails, the motor is automatically started in Bypass.
When the Drive goes to Auto Bypass, the keypad displays “Going into AutoBypass” for 10 seconds. After the delay, the
Drive goes to the Bypass mode and starts the motor (the run command must still be present).
