The eF-785 can act as a network hub for connecting Teknic’s open
ControlPoint™ networked motion and I/O control nodes. These nodes
can control servomotor or stepper motor axes. When using the eF-785
with ControlPoint™ components in charge of the motion control,
controlled stopping of the motion axes within a machine can be
automatically initiated by the eF-785 when a safety shutdown occurs.
This, combined with the eF-785 ’s hazardous power disconnect delay
function, forces the axes to a smooth controlled stop (in the fraction of
the second before power removal) during an E-Stop, interlock open and
most other safety shutdown events. This typically saves the material in
process, reduces wear and tear on the machine, and generally increases
the perceived quality of the machine by the customer.

Create a complete power & safety system for your machine
using the eF-785 by following these simple steps:
1. Complete a risk assessment of your machine hazards, and then
select guard-locks or interlocks for guarded areas.
2. Select the eF-785 configuration options that fit your machine
requirements.
3. Mount
the
eF-785.
4. Select and connect the external 24VDC power supplies and devices
to the eF-785. Example cables are shown in Appendix C of this
manual.
5. Select and connect the external DC motor power supplies and DC
motors to the eF-785. Example cables are shown in Appendix C of
this manual.
6. Connect AC powered servo drives. Example cables are shown in
Appendix C of this manual.
7. Connect any other AC loads.
8. Connect incoming AC power, and if required, an incoming power
disconnect switch.
9. Connect the embedded control computer to the eF-785 using off-
the-shelf cables (modular power cord, USB cable, IEEE-1284
cable).
10. Mount the machine’s on-off switch(es) and connect them to the eF-
785. An example cable including recommended switches is shown
in Appendix C of this manual.
11. Mount the safety system components (e-stop switches, interlock
switches and/or guard locks) and connect them to the eF-785. You
will find recommended devices for all of these components in this
manual.
12.
Optional:
Connect Teknic ControlPoint™ motion and I/O
components via standard Category 5 patch cables.
This manual contains all of the instructions you’ll need to complete each
of these tasks quickly with a minimum of research, while meeting all of
the required safety standards.
