Installation checklist and start-up
101
Starting the supply unit
WARNING!
If the drive is equipped with a brake unit, make sure there
are inverters connected to the intermediate circuit before start. As a rule
of thumb, the sum capacitance of the inverters connected must be at
least 30% of the sum capacitance of all inverters.
If there is not enough capacitive load
at start, the DC voltage will overshoot
the controller voltage limit, causing
immediate start of braking. An
unloaded supply unit keeps the DC
voltage high and the chopper
remains conductive.
Units with line contactors: Close the contactors and start the supply unit
by turning the start switch on the cabinet door from 0 into START
position for 2 seconds.
Checks with the supply unit running
Activate and check the operation of the power loss ride-through
function. (Only if automatic restart is required/allowed after a short power
supply break.)
See chapter
Hardware description
.
Check the settings of the earth fault (ground fault) monitoring device.
See chapter
Electrical installation
.
Application program set-up
Follow the instructions in the
Firmware Manual
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.
Optional function. See delivery
specific circuit diagrams.
Check that the cooling fans rotate freely in the right direction, and the air
flows upwards.
Check visually that the fans rotate in
the direction indicated by an arrow
on the fan housing.
Check the direction of rotation of the motor.
Check the correct operation of the emergency-stop circuits from each
operating location.
