    (Board Status LED) Green LED (Encoder LED) Description: EnDat/SSI Encoder board for Vacon NXP with an input for absolute encoder Sin/Cos type encoder. Allowed slots: B, C, D, E (Sin/Cos signals can only be used in slot C) Type ID:...

  • Page 4: Opt-Be Jumpers

    4 • VACON Installation EnDat is a bidirectional synchronous serial interface for encoders. For example, the absolute encoder position data can be read and encoder parameters can be set via the EnDat connection. It also forwards the messages related to the encoder functions.

  • Page 5: Opt-Be Leds

    Analog Sin/Cos signals deserve some more precautions for noise immunity than pulse encoders. Use of shielded pair cables is recommended. Use one pair for SIN+/SIN- and another pair for COS+/COS- signals. 24-hour service: +358 (0)40 8371 150 • Email: vacon@vacon.com...

  • Page 11: Opt-Ar Jumper Settings

    NOTE! Analog Sin/Cos signals deserve some more precautions for noise immunity than pulse encoders. Use of shielded pair cables is recommended. Use one pair for SIN+/SIN- , one pair for COS+/COS- and another pair for R+/R- signals. 24-hour service: +358 (0)40 8371 150 • Email: vacon@vacon.com...

  • Page 13: Installation

    WARNING! Installing option boards Option boards OPT-BE, OPT-AK and OPT-AR can only be used with Vacon NXP drives. OPT-AK and OPT-AR can be connected to slot C. OPT-BE board can be connected to slots B, E, C or D, but Sin/Cos signals can only be used in slot C. If OPT-BE board is connected to slots B, E or D, the Sin/Cos signals have to be disconnected using the jumpers (see chapter 1.2).
  • Page 14 14 • VACON Installation Open the cover of the control unit. Install the option board in correct slot on the control board of the frequency converter. Make sure that the grounding plate fits tightly in the clamp. Strip the cable at such distance from the terminal that you can fix it to the frame with the grounding clamp.
