Technical details for cantilever axis ELCC

Function and sizes

  • The cantilever axis is attached to the slide as a standard
  • The axis moves in and out of the working area
  • Freely selectable motor positions (turned 4x90°) and mounting kits (axial and parallel) can be retrofitted
  • Vertical and horizontal installation system
  • Size/max. nominal stroke [mm]: 60/1300, 70/1500, 90/2000, 110/2000

 

 

 

Motor position

  • Freely selectable mounting direction up or down
  • Mounting axial, parallel or transverse to the axis
  • Motor alignment 4 × 90°
  • Can be changed at any time
  • Optional mounting kits for third-party motors

 

 

 

Toothed belt variants

  • Wider toothed belt possible for higher forces and dynamic response
  • Three material options

- Durable standard polychloroprene toothed belt with glass fibre cords
- Polyurethane toothed belts with steel cords for packaging applications in the food industry
- Coated polyurethane toothed belt with long service life for greater resistance to lubricants, e.g. in machine tools

 

 

 

Front-unit components

Electrical and pneumatic components on the front unit

  • Easy to select – convenient and fast, directly from the catalogue

Electric rotary module ERMB

  • Rotary axis with any rotation angle >360°

Parallel gripper HGPT-B

  • Sturdy T-slot gripper with a gripping force of up to 6300 N

Semi-rotary drive DRRD

  • Swivelling high loads up to 200°

Robot flange

  • Front end interface for industrial robots in accordance with ISO 9409-1

Position detection

Incremental displacement encoder

  • Contactless position sensing with 2.5 μm resolution
  • Direct monitoring for safety-relevant two-channel solutions
  • Greater positioning accuracy, as elasticity is controlled by the servo drive

Inductive proximity sensor

  • For homing or for sensing the end positions
  • Proximity sensor SIEN-M8 with switching output PNP or NPN
  • Can be installed alongside the displacement encoder

 

 

 

Clamping unit

  • For securely holding the load
  • Spring-loaded brake shoes secure the axis directly onto the guide rail and are released and engaged using compressed air
  • Clamps the upright axis for a secure hold even in the event of a power failure or cable break
  • Double the holding force with second slide and second clamping unit
  • Only suitable for emergency braking
  • Clamping unit can be selected for sizes 70, 90 and 110
  • Not in connection with sealing air

 

 

 

Sealing air

  • Sealing air connection near the recirculating ball bearing guide
  • Minimises the number of particles that get into the axis, e.g. in a dusty environment or on machine tools

 

 

 

Shock absorber

  • Dampens the end position impact of the axis in the event of a collision
  • Prevents damage during set-up, dampens short falling distances of the vertically installed de-energised axis

 

 

 

Additional slide

  • Extends the guide, increases the rigidity with longer strokes and enhances load-bearing capacity, especially when used horizontally
  • Reduces vibrations and significantly shortens oscillations

 

 

 

Central lubrication system

  • 2 lubrication nipples for lubricating the guide cassettes
  • Alternative connection to a central lubrication system
  • Suitable for oils and greases
