7.1 Applying Power to the Drive
Before applying power to the drive, verify that the drive and any associated equipment is ready for operation. Refer to the Pre-start
Checklist section.
W A R N I N G
UNINTENDED START
When the drive is connected to the AC mains, DC supply, or load sharing, the motor may start at any time, causing risk of death,
serious injury, and equipment, or property damage. The motor may start by activation of an external switch, a eldbus command,
an input reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up software, or after a cleared fault condi-
tion.
Press [O] on the LCP before programming parameters.
Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended motor
start.
Check that the drive, motor, and any driven equipment is in operational readiness.
N O T I C E
MISSING SIGNAL
If the status line at the bottom of the LCP reads AUTO REMOTE COASTING, or if 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 5.10 Enabling Motor Operation for details.
Procedure
Conrm that the input voltage is balanced within 3%. If not balanced, correct the input voltage imbalance before proceed-
ing. Repeat this procedure after the voltage correction.
Ensure that any optional equipment wiring matches the installation requirements.
Ensure that all operator devices are in the OFF position.
Close and securely fasten all covers and doors on the drive.
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 congure and operate the drive and motor. These parameter settings are pro-
grammed into the local control panel (LCP) through the dierent LCP menus. For more detail on parameters, see the Programming
Guide.
Parameter settings are assigned a default value at the factory, but can be congured 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 subgroups, if necessary. For example:
