8.6.1.2 Electronic Assemblies
The A25 drive system electronic assemblies include one Power Supply
Module (PSM) and one Servo Amplifier Module (SVM). These compo-
nents are in the servo drive unit, located in the MTC (Machine Tool Cabi-
net).
• The PSM is shared with the X, Y, and Z Servo Amplifier Modules.
Power Supply Module (PSM)
The Fanuc PSM supplies power to the spindle
and servo amplifier modules. The PSM con-
verts the 3-phase AC input voltage to DC volt-
age.
The PSM is a: Model No. PSM-26, Type A06B-
6082-H126.
The PSM contains its own protection and error
detection functions. Two 7-segment displays,
on the front of the PSM display an alarm num-
ber in the event of a PSM fault (
Figure 8-8
).
• See
chapter 5
for details on the self-
diagnostic displays and
appendix A
for detail
on PSM alarms.
Table 8-7
lists the PSM-26 specifications.
