CAUTION: Make sure you select a 24 VDC power supply that meets the spe-
cifications in the preceding table. Using an underrated supply can cause sys-
tem problems and prevent your equipment from operating correctly. See the
following table for recommended power supplies.
Table 3-5. Recommended 24 VDC Power Supplies
Vendor Name Model Ratings Mount
OMRON S8FS-G15024C 24 VDC, 6.5 A, 150 W Side/Bottom
OMRON S8FS-G15024CD 24 VDC, 6.5 A, 150 W DIN-Rail Mount
NOTE: The power requirements for the user-supplied power supply will vary
depending on the configuration of the SmartController EX motion controller and
connected devices. A minimum configuration of the controller, front panel, and
pendant will require 2 A at 24 VDC. However, a 24 V, 5 A power supply is
recommended to allow for additional current draw from connected devices, such
as external IEEE 1394 devices and digital I/O loads.
24 VDC Power Cabling
In order to maintain compliance with many standards, DC power must be delivered over a
shielded cable, with the shield connected to the frame ground at both ends of the cable, as
shown in the following figure. Conductors should be 1.5 mm
2
to 1.85 mm
2
(16 to 14 AWG) in
size. The maximum length for the 24 VDC cable is 10 meters.
