6.6 System Start-up
WARNING
MOTOR START
Failure to ensure that the motor, system, and any
attached equipment are ready for start can result in
personal injury or equipment damage. Before start,
•
Ensure that equipment is safe to operate under
any condition.
•
Ensure that the motor, system, and any
attached equipment are ready for start.
The procedure in this section requires user-wiring and
application programming to be completed. The following
procedure is recommended after application set-up is
completed.
1.
Press [Auto On].
2.
Apply an external run command.
Examples of external run commands are a switch,
button, or programmable logic controller (PLC).
3.
Adjust the speed reference throughout the speed
range.
4.
Ensure that the system is working as intended by
checking sound and vibration level of the motor.
5.
Remove the external run command.
If warnings or alarms occur, see

6.7 Parameter Settings
NOTICE
REGIONAL SETTINGS
Some parameters have different default settings for
international or North America. For a list of the different
default values, see
chapter 10.2 International/North
American Default Parameter Settings
.
Establishing the correct programming for applications
requires setting several parameter functions. Details for
parameters are provided in the
programming guide
.
Parameter settings are stored internally in the drive,
allowing the following advantages:
•
Parameter settings can be uploaded into the LCP
memory and stored as a back-up.
•
Multiple units can be programmed quickly by
connecting the LCP to the unit and downloading
the stored parameter settings.
•
Settings that are stored in the LCP are not
changed when restoring factory default settings.
•
Changes made to default settings as well as any
programming entered into parameters are stored
and available for viewing in the quick menu. See
chapter 3.6 Local Control Panel (LCP)
6.7.1 Uploading and Downloading

card, which is located within the drive. The upload and
download functions move the parameters between the
control card and the LCP.
1.
Press [Off].
2.
Go to
parameter 0-50 LCP Copy
and press [OK].
3.
Select 1 of the following:
3a
To upload data from the control card to
the LCP, select
[1] All to LCP
.
3b
To download data from the LCP to the
control card, select
[2] All from LCP
.
4.
Press [OK]. A progress bar shows the uploading or
downloading process.
5.
Press [Hand On] or [Auto On].
6.7.2 Restoring Factory Default Settings
NOTICE
LOSS OF DATA
Loss of programming, motor data, localization, and
monitoring records occurs when restoring default
settings. To create a back-up, upload data to the LCP
before initialization. Refer to
Downloading Parameter Settings
.
Restore the default parameter settings by initializing the
unit. Initialization is carried out through
parameter 14-22 Operation Mode
or manually.
