2 Function
The slides of the guide axis support a load whilst moving.
When the load is shifted along the direction of the axis, the slide follows very
smoothly.
An extended slide enables a loading with higher torques.

3 Application
The FDG-...-ZR-RF has been designed as a basic structure for boom or portal
systems consisting of a driving linear axis and a passive guide axis.

4 Conditions of use
Please note
SMake sure that the specifications in this chapter are always observed.
The product will then function correctly and reliably.
SCompare the maximum values specified in these operating instructions with
your actual application (e.g. forces, masses, temperatures, torques).
Only if the loading limits are observed can the product be operated in
accordance with the relevant safety guidelines.
STake into account the ambient conditions
at the location.
Corrosive environments will impair the
service life of the product.
SRemove the packing from the product.
The packing is intended for recycling
(except for: oiled paper which must be
disposed of).
SObserve the specifications applicable to your location, as well as all local and
national laws and regulations.
SUse the product in its original state without undertaking any modifications.
SMake sure that safety measures cannot be ignored.
5 Transport and storage
SConsider the weight of the FDG-...-ZR-RF.
It weighs up to 100 kg.
SIf necessary fasten the slide, which runs
very smoothly, with adhesive tape.

Mechanical components
SMake sure that this condition is observed:
Rated stroke FDG-...-ZR-RF ≥Rated stroke drive axis
Example (type plates): FDG-40-800-ZR-RF ≥DGE-40-800-ZR-RF
Only in this way will the multi-axis system function free of collision in the end
positions.
SPlease note that the rated stroke can be defined differently depending on the
axis and the manufacturer:
Definition of the rated stroke

h: Rated stroke r: Stroke reserve
SPosition the FDG-...-ZR-RF without tension
or bending (evenness of mounting surface:
0.2 mm/30 cm).
Axis fastening kits, centre supports and foot
fastenings will assist you here.
Please note
Take into account that, in the case of heavy loadings, the axis must not be
fastened only at the cover caps.
Excessive tensile loads will cause the cover screws to be pulled out.

In the case of articles with large stroke lengths:
SUse centre support type MUP-... .

SFasten the axis fastening kits or centre supports to the FDG-...-ZR-RF as shown
in the following diagram:
If necessary, sliding blocks in the profile grooves can serve as fastening devices.
If the FDG-...-ZR-RF is used in conjunction with a drive axis type DGE-... or
DGP(L)-...:
SUse the distances between supports of the drive axis also for the FDG-...-ZR-RF.
In this way you will avoid distortion due to uneven bending.
STighten the fastening screws for the transverse fastening at first only slightly
(see Fig. 7: Q).
The FDG-...-ZR-RF can then be further adjusted until it is mounted correctly.
Fitting the fastening elements
SMake sure that the axis fastening kit or
the centre supports are situated outside
the collision range of the slide, by pushing
the slide once over the complete position
ing path.

If the FDG-...-ZR-RF is used in conjunction with a drive axis type DGE-... or
DGP(L)-...:
1. Make sure that the slide surfaces of both
axes lie at the same level within the com
plete positioning stroke.
2. Position the FDG-...-ZR-RF exactly parallel
to the drive axis.
3. Place the bridge (see Fig. 2) and the work
load onto the slides of the FDG-...-ZR-RF and
the drive axis as follows:
– The tilting torque of force F parallel to the
cylinder axis and distance d remains low.
Force F includes here the inertial force
F = m a, the force due to weight and
possible external forces.
– Only loadings within the framework of
the permitted values are effective
(see“Technicalspecifications”).
4. Push the bridge over the complete stroke path from one end position to the
other.
The guide axis will then position itself free of distortion to the drive axis.
5. Tighten the fastening screws (see Fig. 7: Q) of the guide axis.
Check whether shock absorbers or stops are also required externally.
Interrogating the slide positions
SUse sensors with inductive switching in conjunction with ferritic switching
lugs.
SComplete the fitting of the sensors in accordance with the operating instruc
tions for the sensors and for the drive axis.
You can protect unused sensor grooves against dirt deposits at best with cover
rails as described in the chapter “Accessories”.

7 Commissioning and operation
Warning
SMake sure that:
– nobody can place his/her hand in the
path of the moving load (e.g. by
providing a protective screen)
– there are no objects within the
positioning path of the axis.
It must not be possible to touch the
FDG-...-ZR-RF until the mass has come to
a complete stand.
Please note
The slots in the cover caps enable objects (e.g. nuts or screws), which have
fallen unintentionally into the groove, to be extracted.
Warning
Objects ejected from the cover caps can
cause injury to human beings or damage
to property.
SMake sure that nobody can be hit by
these objects if he/she is in their path
(e.g.by providing a protective screen).
SApply current to the drive motor at first at
low speed and with low torques.
The slide will then move slowly over the
complete positioning path.
