Installing Your 1394 DC Link Module
(Catalog Number 1394-DCLM)
Introduction
This publication provides installation instructions for adding the 1394
DC Link Module to your 1394 system. Use these instructions in
conjunction with the 1394 Digital AC Multi-Axis Motion Control
System User Manual (publication 1394-5.0). The 1394-DCLM:
•
provides additional capacitance to decrease shunt use

Mounting the 1394-DCLM
To mount the 1394-DCLM hardware:
1. Install the top mounting fastener on the system panel for the
1394-DCLM. The head of the fastener must be at least 6.35 mm
(0.25 in.) from the panel.
2. Hang the 1394-DCLM on the top mounting fastener.
Important: The 1394-DCLM must be the last (or right-most)
module in the 1394 system. This is the only module
that is ever mounted to the right of the 1394-DIM,
if used. If the 1394-DCLM is used as a link between
two systems, the total wire distance between 1394DCLMs cannot exceed 3 meters (9.84 ft).
3. Engage the alignment tab so the 1394-DCLM is connected to the
module on its left.

Important: If you are using the 1394-DCLM for additional
capacitance (stand-alone), leave the power plug
(catalog number 1394-CPDCP) attached to the front
underside of the module and apply power to your
system.

If you are linking two systems together, install the second 1394DCLM in the second system. The total wire distance between 1394DCLMs cannot exceed 3 meters (9.84 ft).
Connecting 1394-DCLMs Together
You can connect two 1394 systems together using either a 1.5 meter
(4.92 ft) cable (catalog number 1394-CPDC-0015) or 3 meter
(9.84 ft) cable (catalog number 1394-CPDC-0030).
To connect 1394-DCLMs together:
1. Remove the power plug from the front underside of each 1394DCLM using a phillips screwdriver.

3. Secure the cable to the 1394-DCLMs with the screws provided
(4M x 10) using 12-15 lb-in. of torque.
4. Modify the start/stop circuit so system 2 (slave DC link) is wired
in series to system 1 (master DC link). Figure 8 illustrates GMC
or GMC Turbo system modules connected together.

Important: For the CNC interface module, this relay indicates
E-stop status. Input terminal 1 is part of the E-stop
contactor and is rated at 30V DC, 1.4A.
5. Set the system module DC link mode for the master (and slave)
module. Refer to the following table.
Note:
Mode
0 (master)
The master 1394-DCLM must always be in mode 0.
480V 3 Phase

Indicates
Normal operating condition. The 9/440
and CNC interface can only operate in this
mode (mode 0).

Three-phase power is connected to the
master only (first system). This mode is not
supported by firmware version 3.7 for the
GMC module.
Important: Use the table below when assigning the master/slave
system module configuration.
For this mode:

Checking for a Blown Fuse
To check the 1394-DCLM for a blown fuse:
1. Remove power from your system including the 1394-DCLM.
!
!
ATTENTION: This system may have multiple
sources of power. More than one disconnect switch
may be required to de-energize the system. To avoid
shock hazard or personal injury, assure that all power
has been removed before proceeding.
ATTENTION: This product contains stored energy
devices. To avoid hazard of electrical shock, verify that
all voltage on the capacitors has been discharged before
attempting to service, repair, or remove this unit. You
should only attempt the procedures in this document if
you are qualified to do so and familiar with solid-state
control equipment and the safety procedures in
publication NFPA 70E.
2. Remove the terminator from the right side of the 1394-DCLM.
