Starting The Supply Unit; Checks With The Supply Unit Running; Supply (Line-Side Converter) Program Set-Up; Application Program Set-Up - ABB ACS800-37-0060-3 Hardware Manual

Action
Close the auxiliary circuit On/Off switch (Q100) if present.

Starting the supply unit

Close the main switch/disconnector (Q1).
Units with emergency stop: Turn the Start switch on the cabinet door
from 0 into START position for 2 seconds, then release the switch and
leave it in position 1.

Checks with the supply unit running

Check the settings of the earth fault (ground fault) monitoring device (if
present).

Supply (line-side converter) program set-up

Parameters of the IGBT supply unit need not be set during the start-up
procedure, or in normal use. In case the parameters of the supply unit
need to be changed, switch the control panel (optional) to view the line-
side converter as described in section
Alternatively, a PC equipped with a programming tool (e.g.
DriveWindow) can be connected to channel CH3 of the inverter unit's
RDCU.
Note: It is recommended to set parameter 16.15 I/O START MODE to
DI2 LEVEL if
• the motor is started and stopped frequently. This prolongs the life of
the charging contactor,
• the drive is equipped with the emergency stop option,
• when it is required to start the motor without delay after the start
command, or
• if the drive is connected to a common DC bus. Otherwise the
charging resistors may be damaged.
Note: The output voltage of the drive can be raised using a parameter
setting; for example, it is possible to run a 500 V motor off a 400 V
supply. Contact your local ABB representative for more information.

Application program set-up

Follow the instructions in the Firmware Manual of the inverter unit to start
up the drive and to set the drive parameters.

On-load checks

Check that the Prevention of Unexpected Start function (if installed)
works:
• Start and Stop the drive and wait until the motor has stopped.
• Open the Prevention of Unexpected Start switch (mounted on a control
desk).
• Give a Start command. The drive should not start.
• Reset the drive.
Check that the cooling fans rotate freely in the right direction, and the air
flows upwards.
Check the direction of rotation of the motor.
Check the correct operation of the emergency-stop circuits from each
operating location.

Optional function. See delivery
specific circuit diagrams.
Check visually that the fans rotate in
the direction indicated by an arrow
on the fan housing.
