Optionally, 4-stage filtering may be added as an upgrade to DC motor
drive configurations if additional EMI filtering is required.

Using ControlPoint™ components can greatly simplify wiring
complexity, reduce integration effort, and decrease the number of
assemblies in your machine. Ultimately this will save money and help
reduce errors in design and implementation. ControlPoint™ also
provides a controlled shutdown function for all connected motor drives
when an E-Stop is detected or door interlocks are opened. This works
seamlessly with the optional eF-785 Power-Off Delay to provide very
controlled machine shutdowns.
This position of the eF-785 part number indicates the presence ( C ) or
absence ( X ) of the optional Teknic ControlPoint™ network hub and
integrated 40V network power supply. If you are currently using Teknic’s
ControlPoint™ components, you’ll quickly realize the benefits of
incorporating the CP network hub and 40V network power supply into
your eF-785.
If your design does not include the ControlPoint™ hub with 40VDC
network power supply, order your eF-785 with an X in the indicated
position. With or without ControlPoint™ options, the eF-785 provides
excellent power distribution and safety control functionality.

The eF-785 offers you some options as to how quickly hazardous power is
removed from the Main Area of your machine. Q: When can this option
be valuable? A: In cases where the sudden removal of power from a
motor axis could cause significant (read expensive) damage to the
machine, its payload, or both.
The safety guidelines outlined by EN 954-1 allow for a power-off delay
as long as certain criteria are met, and the eF-785 meets these guidelines.
The delay should be selected to allow for a controlled stop of the relevant
motor axes in the event of an E-stop event. The delay can also be
independently configured for the Load/Unload Area, if the machine is
segmented. Available options and codes are listed below.
N No Delay Required
F Fast Delay (150mS) - For smaller axes or axes where high rates of
deceleration are tolerable.
S Slow Delay (450mS) - For larger axes or axes where more time is
required to complete a controlled removal of power.
