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
