4.0 STARTUP
Ensure that the drive has been installed according to the previous
guidelines. Also, ensure that the unit has been wired according to the
schematics. Check that all connections are tight and that the motor can
rotate freely.

AC input voltage selection
Before power is applied, confirm that the voltage selection plug on the
AA1128 card matches the supply voltage. DG2P-15 drives are factory
set for 240 VAC input and are not reconfigurable. DG2P-10 drives may
be configured for either 120 VAC or 240 VAC as follows. Locate 2 wire
jumpers and a nylon plug housing in a plastic bag attached to the
heatsink. Insert the wire jumpers into the housing according to one of
the two drawings below depending on the AC input voltage. Insert the
plug into connector JMP1. If the input voltage is 240 VAC then
jumper J4 must be removed.
120 VAC 240 VAC
•
Field voltage selection
Confirm that the field voltage is configured to match the field voltage
of the motor according to its nameplate rating. Permanent magnet
motors do not require field voltage configuration. Terminals 12 and 13
are jumpered as the factory standard default.

All controls have been preset at the factory and should not require
further adjustment.
The DG2 PLUS has been factory set for armature voltage feedback. To
use tachometer feedback, remove the "ARM" link and install the
"TACH" link (LK-3).
The "IR COMP" trimpot is not used with tachogenerator feedback, and
must remain fully counterclockwise.
4.1 Inspection
4.2 Prestart adjustments
To prevent drive runaway,
be very careful to estab-
lish tachogenerator po-
larity with the motor ro-
tating in the desired di-
rection. Then connect
tach (+) to terminal 2 and
tach (-) to terminal 1.
