GX7R ASD Quick Start Guide
Installation and Connections
The
GX7R ASD
may be set up initially by performing a few simple configuration settings. To operate
properly, the ASD must be connected to a power source. Connect the 3-phase AC input lines,
C
-
B
-
A
, to
the
PB1
terminal block terminals
A
,
B
, and
C
, respectively.
The control terminals of the ASD may be used by connecting the terminals of the
Motoring Terminal
Board
(P/N 48570) to the proper sensors or signal input sources (see the section titled
Note:
The optional
ASD-Multicom
boards
may be used to expand the I/O functionality of
the ASD. See the
GX7R ASD Install and Op Manual
for more information on the
available options.
Note:
The
GX7R ASD
uses two control boards and two terminal boards;
Motoring
and
Regeneration
. Unless otherwise specified, the terms
Control Board
and
Terminal
Board
refer to the
Motoring Control
and the
Motoring Terminal Boards
.
The output terminals of the ASD (T1, T2, and T3) must be connected to the motor that is to be
controlled (see
).
As a minimum, the installation of the ASD shall conform to
Article 110
of the
NEC
, the
Occupational
Safety
and
Health Administration
requirements, and to any other local and regional industry codes
and standards.
The
Startup Wizard
assists with the initial configuration of the commonly used GX7R ASD
parameters. See the section titled
for additional information on the
Startup
Wizard
. The
Startup Wizard
is launched by configuring the system to start the wizard automatically
upon a system restart.
Installation Notes
Do Not
apply commercial power to the output terminals
T1
,
T2
, or
T3
.
If an output contactor is used for bypass operation, it must be interlocked such that commercial power is
never applied to the output terminals of the ASD (T1, T2, or T3).
If a secondary magnetic contactor
(MC) is used between the output of the ASD and the motor, it should
be interlocked in series with the
ST – CC
connection such that the
ST – CC
connection is disconnected
before the output contactor is opened.
Do Not
open and then close a secondary magnetic contactor between the ASD and the motor unless the
ASD is off and the motor is not rotating.
Note:
Re-application of power via a secondary contact while the ASD is on or while the
motor is still turning may cause ASD damage.
Disconnect the ASD from the motor before megging or applying a bypass voltage to the motor.
When a brake-equipped motor is connected to the ASD, it is possible that the brake may not release at
startup because of insufficient voltage. To avoid this,
Do Not
connect the brake or the brake contactor to
the output of the ASD.
On some devices the
ST
-to-
CC
connection is further enhanced by the operation of the
MS1 AUX
relay
circuit. The
MS1 AUX
relay circuit is normally open and closes the
ST
-to-
CC
connection (via ST1)
