Connecting the Power Supply Module to the Amplifiers
The Module Interface Connection
The modules are consecutively attached, or “daisy chained”, to one another through the module
interface connectors (
JX..B
resp
. CX..B
for output and
JX..A
resp.
CX..A
for input) located on
each power supply module and spindle/servo amplifier unit. The connector JX.. stands for
signal connection, and the connector CX.. stands for a power supply or emergency stop
connection. The power supply module will connect to the first amplifier, and then the first
amplifier to the second and so on.
Locate the cable you will use to connect the power supply
module to the first amplifier module. This cable kit is
identified as GE Fanuc part :
LX660-2077-T200/L300R0 300 mm length
LX660-2077-T201/L300R0 300 mm length
LX660-2077-T202/L300R0 300 mm length
LX660-2077-T200/L200R0 200 mm length
LX660-2077-T201/L200R0 200 mm length
LX660-2077-T202/L200R0 200 mm length
Insert one end of the cable LX660-2077-T200/L… into the
connector labeled
JX1B
on the face of the power supply
module.

.
Connect the other end of the cable into the connector labeled
JX1A
on the first
amplifier module.
Note
If your system has a spindle amplifier, it is normally the first connection.

.
You can add spindle/servo amplifier modules to the system by “daisy chaining” them
the same way. Just connect
JX1B
from the first amplifier to
JX1A
on the second
amplifier and so on.
7
.
The last amplifier in this chain will have an unused output connector (nothing plugged
into
JX1B
). You have to insert the terminating connector here to allow the motors to
be driven. This connector is supplied by GE Fanuc and should be connected to
JX1B
on the power supply module when you receive it.
The 24V DC Connection
This power is connected as follows:
1
.T
he cable LX660-2077-T201/L… connects the 24V DC supply
between the modules.
2
.
Insert one end of this cable into the connector labeled
CX2B
on the power supply
module.
3
.
Insert the other end of this cable into the connector labeled
CX2A
on the first
amplifier.
4
.
When adding amplifier modules to the system, simply connect
CX2B
on the first
amplifier to
CX2A
on the second amplifier and so on.
