Wiring 1394 GMC and GMC Turbo Systems 4-19
Connecting a GMC and GMC Turbo
to a 1394-DIM
The 1394-DIM acts as an interface between one 1394 GMC/GMC
Turbo system module and the external axis drive(s).
On the 1394 x -SJT xx -C, -C-RL, -T, and -T-RL, the 1394-DIM acts in
place of one to four axis modules. On the 1394C-SJT xx -L and -L-RL
the 1394-DIM acts in place of one axis module. The 1394-DIM
passes a standard servo output signal from the system module to each
external drive connected to the 1394-DIM. Using a 1394-DIM as part
of a 1394 system lets you control external drives and motors of any
size.
1394-DIM System Example
The figure below shows an example of a 1394 GMC/GMC Turbo
System after connecting a 1394-DIM.
Figure 4.18
A 1394-DIM Connected to a GMC or GMC Turbo
Figure 4.18 shows the 1394-DIM connected to a 1394 GMC Turbo
with two 1394 axis modules. A 1326AB-B
xxxx motor is directly
connected to each of the 1394 axis modules. Two servo amplifiers
with motors are connected to the 1394-DIM. It can accept two
because there are two axis modules connected to the 1394 GMC
Turbo. The encoders attached to the motors have encoder feedback
cables connected to the system module.
