Removing EK8./EK9./AK8./AK9./RK8M – Add-on encoder set with M23 connector directly on KIGA encoder

  1. For size 71 – 132S with forced cooling fan: Remove the screw [22].
  2. For size 71 – 132S with forced cooling fan: Remove the screws [34] and the washers [33].
  3. For size 132M – 355 with forced cooling fan: Remove the screw [22].
  4. Without forced cooling fan: Remove the screws [34]/[1711].
  5. Remove the safety cover [361]/[657] or the forced cooling fan [170] from the motor. When doing this, slide the cable grommet [269] out of the recess.
  6. With forced cooling fan: Remove the signal cable from the cable retainer [1900].
  7. Unscrew the screws [232].
  8. Without forced cooling fan: Remove the screws [22].
  9. Remove the fan guard [35] over the encoder [220]. Guide the M23 connector [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] or the nut [734], 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].
