    EGMENTED ACHINE UPPORT The eF-785 can be configured so that AC power to mechanical hazards is controlled independently in two different functional areas of a machine. This means that an operator can easily power down the mechanical hazards in one part of a machine (Load Area) while the Main Area of the...
  • Page 10: Controlled Stopping Function (Controlpointâ„¢ Only)

    ™ O ONTROL OINT 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.
  • Page 11 OEM Machine Manufacturer, in mind. Our objective is to provide you with all of the information you need to successfully visualize, integrate and install the eF-785 in your machine. To that end we’ve included a complete set of cable drawings, each with a comprehensive bill of materials.

  • Page 17 (Q). TAGE ILTERING The basic level of EMI filtering offered for the eF-785 is two-stage (Dual) filtering indicated by the letter D in the position shown above. The 2- stage option is standard in configurations where only DC powered motor drives are present in the machine (i.e.
  • Page 18 OFF DELAY PTIONS 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.
  • Page 19 Power up with Soft Shutdown enabled - An operator initiates the machine power-up cycle by pressing the machine’s front panel “on” button (which is wired into the eF-785). The machine powers up and the eF-785 sends AC power to the host computer which then powers up as well.
  • Page 20 U G U S T Power down with Soft Shutdown enabled – When the operator powers down the host PC, the USB signal to the eF-785 turns off. When the eF-785 no longer detects the USB signal, it shuts down the entire machine.
  • Page 21 Hazardous power availability vs. E-Stop switch status EVISION RMWAR The final position of the eF-785 part number contains the firmware revision of the embedded Teknic ControlPoint™ network hub (NC-540).

  • Page 24: Mounting Orientation

    If a vertical mount is chosen, the fan should be “up” to assure proper ventilation and cooling action (see diagram). Never mount the eF-785 such that the front panel faces directly down or up. Refer to the “Unacceptable Mounting Orientation” diagram below.
  • Page 25: Rack Slides

    Often, the bottom of a machine offers the coolest ambient air temperatures. LIDES If you plan to rack mount your eF-785, Teknic recommends the Accuride model c 2807-20 rack drawer slides. This model is compatible with the thread inserts on the side panel of the eF-785.
  • Page 26: Step 4: Set Up The 24Vdc Power Distribution

    OWER SUPPLIES The 24VDC supplies are connected to the 24VDC Supply connector J5 (see figure below), located on the rear panel of the eF-785. This connector not only serves to provide two different control modes for AC line voltage to power the supplies (described below), it also receives the...
  • Page 27 Please refer to the following schematic fragments for details. Note that although the eF-785 can remove AC power to externally connected 24VDC supplies, it does not provide any means for quick-discharge of the connected supplies once AC power is removed. This is usually not an issue if a switching supply is used for the 24V, which is common, the 24VDC will usually drop very quickly, in less than a few hundred milliseconds.

  • Page 32: Step 5: Set Up Dc Motor Power Distribution 48-90Vdc

    Connector P6, on the rear panel of the eF-785, provides switched Main AC power to the DC power supply, and connects the DC output of the supply back to the eF-785. Though we often refer to this as the “75VDC Power Distribution” in the manual, the permissible voltage range for this supply is 48-90VDC.
  • Page 33: Connecting The Loads (Dc Motor Drives) (P7A, P7B, J8A, J8B)

    The negative (return) lead of the power supply should not be connected to safety ground at the power supply. This connection is made internally in the eF-785, and to avoid any ground loops, should not be done externally.
  • Page 34 Refer to Appendix C for cable drawings. The Main DC motor power connectors (P7A, B) are keyed differently than the Load DC motor power connectors (J8A, B) to prevent incorrect connections during installation of the eF-785. See illustration below.

  • Page 44 ONNECTIONS Two USB connectors (one Type A and one Type B) are provided on the rear panel of the eF-785. These USB connectors provide only a pass- through connection and are necessary only if the Soft Shutdown feature is enabled.
  • Page 45: Step 10: Mount And Connect The Power/Enable Switch(Es)

    Using a combination switch such as this not only allows you to provide front panel controls using only one component, but also the front panel wiring harness from P14 on the eF-785 to this switch can be wired with one straight point-to-point cable. Teknic recommends a 22 mm rotary switch such as the Omron/A22W-3AG-24A-11.
  • Page 46 “actuation” of the Off button from the control computer. This feature, known as the Soft Shutdown, works by connecting the control computer to P16 on the eF-785 via a standard USB cable. When the control computer is shut down, the 5V from the USB port is removed. The eF- 785 immediately detects the USB voltage change of state from +5v to 0V and turns off AC Control Power.
