7.1 Applying Power
WARNING
UNINTENDED START
When the drive is connected to AC mains, DC supply, or
load sharing, the motor can start at any time, causing
risk of death, serious injury, and equipment, or property
damage. The motor can start by activation of an external
switch, a fieldbus command, an input reference signal
from the LCP or LOP, via remote operation using MCT 10
Set-up software, or after a cleared fault.
To prevent unintended motor start:
•
Press [Off] on the LCP before programming
parameters.
•
Disconnect the drive from mains whenever
personal safety considerations make it
necessary to avoid unintended motor start.
•
Check that the drive, motor, and any driven
equipment are in operational readiness.
NOTICE
MISSING SIGNAL
If the status at the bottom of the LCP reads AUTO
REMOTE COASTING, or
alarm 60, External interlock is
shown, it indicates that the unit is ready to operate but
is missing an input signal on, for example, terminal 27.
See
chapter 5.9.4 Enabling Motor Operation (Terminal 27) .
Apply power to the drive using the following steps:
1. Confirm that the input voltage is balanced within
3%. If not, correct the input voltage imbalance
before proceeding. Repeat this procedure after
the voltage correction.
2. Ensure that any optional equipment wiring
matches the installation requirements.
3. Ensure that all operator devices are in the OFF
position.
4. Close and securely fasten all covers and doors on
the drive.
5. Apply power to the unit, but do not start the
drive. For units with a disconnect switch, turn the
switch to the ON position to apply power to the
drive.
7.2 Programming the Drive
7.2.1 Parameter Overview
Parameters contain various settings that are used to
configure and operate the drive and motor. These
parameter settings are programmed into the local control
panel (LCP) through the different LCP menus. For more
detail on parameters, see the product-specific
programming
guide .
Parameter settings are assigned a default value at the
factory, but can be configured for their unique application.
Each parameter has a name and number that remain the
same regardless of the programming mode.
In the Main Menu mode, the parameters are divided into
groups. The 1
st
digit of the parameter number (from the
left) indicates the parameter group number. The parameter
group is then broken down into sub-groups, if necessary.
For example:
0-** Operation/Display Parameter group
0-0* Basic Settings Parameter sub-group
Parameter 0-01 Language Parameter
Parameter 0-02 Motor Speed Unit Parameter
Parameter 0-03 Regional Settings Parameter
Table 7.1 Example of Parameter Group Hierarchy
7.2.2 Parameter Navigation
Use the following LCP keys to navigate through the
parameters:
•
Press [
▲
] [
▼
] to scroll up or down.
•
Press [
◄
] [
►
] to shift a space to the left or right of
a decimal point while editing a decimal
parameter value.
•
Press [OK] to accept the change.
•
Press [Cancel] to disregard the change and exit
edit mode.
•
Press [Back] twice to show the status view.
•
Press [Main Menu] once to go back to the main
menu.
