6.)
Verify that the
OM
has the correct
PM
installed and that
OM
jumpers are in
the
desired locations
(see Figure 5-2 for
PM
location and jumper locations). Connect all interface cables
to
the
OM
.
7.)
Apply incoming power with the
OM
inhibited and observe the
OM
LEOs.
The green
LED
should tum
on and remain on while the three red
LEOs
should
tum
on for about 1 second and then tum off and
remain off. Check that the
OM
fan is operating
by
checking that air
is
coming
out
of
the top
of
the
OM
near the mount plate.
8.) Connect a serial· terminat
to
·
OM
connector·
P6.
·· Monitor position feedback and observe that
position increases positively when the motor shaft is rotated CW as viewed facing the motor drive
end (refer
to
Section 5.2.3 for serial terminal operation).
9.) Remove incoming power and observe that all module
LEOs
tum
off within one second.
10
.) It
is
safest
to
disconnect the motor(s) from the mechanicalload(s) when initially checking out the
system. If this is not possible, then take adequate precautions in the event
of
a fault.
11
.) Connect
R,
S, T, and G
of
motor to R, S, T, and GND of the
OM
. With the
OM
inhibited reapply
incoming power and observe proper power up diagnostics as indicated
by
module
LEOs
.
12
.) Using the serial terminal
or
a BRU-Series control station, set a low current limit
(25%
is
a typical
value). Apply a small positive voltage (about
0.5V)
to
the
VCS
input of the
OM.
Enable the
OM
and
observe
CW
rotation
of
the motor shaft as viewed facing the motor drive end. If
motor
does not
tum
CW then check that motor power wires and encoder wires are connected
to
the
OM
proper1y
.
13.) Now that the system installation is verified, return the current limit
to
a value
to
suit the application.
The final current limit value should be saved
in
the personality module (see Section 5.2.3.2.

.
5.2 Adjustments
5.2.1 Power Supply Module Adjustments (BRU-500 Only)
There are no
PSM
adjustments. The wide input voltage range of 88-265
VAC
rms is accommodated
automatically and the dissipative shunt regulator automatically tracks the
DC
bus.
The
PSM
has one jumper,
W1,
that
is
used
to
activate
or
deactivate the use
of
an external
PSM
enable
input. The jumper location and description are shown in Figure
5-1.
The
PSM
is
factory configured with
the external enable input deactivated. This means that the
PSM
will supply the
DC
bus if appropriate input
voltages are connected to the
PSM
input and an external enable input will have
no
effect
on
the
PSM
operation. See Section 4.4 for more information concerning use
of
jumper
W1.
5.2.2 Drive Module Adjustments
There are no
OM
potentiometers
to
adjust and in most situations the PM (Personality Module) provides all
the necessary pre-adjustments so that absolutely no adjustments are required. Refer
to
Section 9.3 which
explains the
PM
model number and Section 5.4 which covers
PM
installation. There is also an "automatic
tuning" feature which allows the user
to
set
up
the BRU-Series system on the machine and have
it
tune
itself. Refer to Section 5.
3.1
for information and conditions for using the automatic tuning feature.
A serial interface
is
provided
to
change modes, modify tuning, change limit values. monitor certain
variablesj status, or obtain more diagnostics information than provided by the
LEOs
. Refer
