Removing EK8./EK9./AK8./AK9./RK8M – Add-on encoder set with integrated A1GA encoder connector with connection cover or without A2GA connection cover

  1. Unscrew the screws [E].
  2. Remove the connection cover [619] from the connection adapter [U].
  3. Loosen the screws [D] in the lower part [C].
    • Only unscrew the screws [D] to such an extent that the connection adapter [U] can be moved in the recess of the safety cover [657]/forced cooling fan [170].
  4. With forced cooling fan: Unscrew the screws [22].
  5. Without forced cooling fan: Unscrew the screws [34]/[1711].
  6. Remove the safety cover [361]/[657] or the forced cooling fan [170] from the motor. When doing this, slide the connection adapter [U] out of the recess.
  7. With forced cooling fan: Remove the signal cable from the slot/3 wings of the cable retainer [1900].
  8. Unscrew the screws [232].
  9. Remove the fan guard [35] over the encoder [220]. Guide the connection adapter [U] with the signal cable through the cutout of the fan guard [35].
  10. For size 132M – 355 with forced cooling fan: Remove the screw [936], the nuts [734]/[937], the spacer bushing [934], and the torque bracket [935].

    11. NOTICE

    In the case of encoders RK8M, EK8W, AK8H, AK8W, EK8Z, EK9Z, and AK8Z on DR2C.. motors, loosening the central retaining screw [A] of the encoder [220] or loosening the insulation coupling [1891] of the motor or encoder shaft desynchronizes the encoder and motor rotor.
    Higher motor losses and lower torques.
    • Perform a new adjustment.
  11. Unscrew the screw plug [A] of the encoder [220].
  12. Loosen the central retaining screw of the encoder [220]. Use a tool that is at least 45 mm long for this.
    • If the central retaining screw of the encoder [220] cannot be loosened, counter-tighten the spanner flat SW10 of the encoder shaft.
  13. Loosen the cone connection.
    • Encoder EK8., AK8W, AK8Y, RK8M: To loosen the cone connection, continue turning the central retaining screw of the encoder [220] counterclockwise.
    • Encoder AK8H: Continue turning the central retaining screw of the encoder [220] counterclockwise. To loosen the conical connection, screw an M6 screw (≥ 70 mm long) into the bore.
  14. Remove the encoder [220] from the rotor [1] or from the coupling [233]/[1891].
