.) Connect a serial terminal to DM connector P6. Monitor position feedback and observe that
position increases positi
vely
when the motor shaft is rotated
CW
as
viewed facing the motor
drive end (refer
to
Section 5.2.3
for
serial terminal operation).
12.) Remove incoming power and observe that all module LEDs tum
off
within one second. Measure
DC bus to insure voltage is below 15 VDC.
13.) It is safest to disconnect the motor(s) from the mechani
ca
l load(s) when initially checking out the
system.
If
this is not possible, then take adequate precautions in the event
of
a fault.
14.) Disconnect all interface cables from DMs and remove all
DM
covers. Connect R, S, T, and G
of
motor to R, S, T, and GND
of
DM
. Install all
DM
covers. Connect all interface cables to the
proper DM. With each DM inhibited reapply incoming power and observe proper power up
diagnostics as indicated by module LEDs.
15.)
Us
i
ng
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
each
DM
. Enable each
DM and observe
CW
rotation
of
each 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
DM
properly.
16.) Inhibit all DMs and tum
off
input power. Measure DC bus to be sure that it is below 15 VDC.
17 .) 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
5.2.3.2.3).

DANGER OF ELECTRICAL SHOCK OR BURN. ONLY QUALIFIED
INDIVIDUALS SHOULD

ON THIS EQUIPMENT.
DISCONNECT
ALL
POWER BEFORE WORKING ON EQUIPMENT.
DANGEROUS VOLTAGES
MAY
EXIST AFTER POWER IS
REMOVED!
Measure
vo
ltage between DM terminals marked L 1, L2/N to insure incoming power is off. Also
measure voltage between terminals marked L 1
AUX
, L2/N AUX,
if
used , to insure power is
off
.
Observe that green LED is
off
.
Disconnect input wires connected to terminals L 1, L2/N (and terminals L 1 AUX, L2/N AUX,
if
used
).
Arrange these wires to
sate
position
for
testing
of
incoming voltage.
Turn incoming power
on
and measure line voltage to insure that it is
in
the proper voltage range.
If
incoming power is the correct voltage then tum power
off
and reconnect the wires to terminals
L 1, L2/N (and terminals L 1 AUX, L2/N AUX, if used) .
With incomi
ng
power still
off
, disconnect motor leads from
DM
terminals R, S, and
T.
Verify with
an
ohmmeter .that ·the f.esistance .between DM terminals R to GND, S to GND, and T to GND is
1
OOk
ohms minimum.
