1 Important information
1.1 About these repair instructions
This document contains important information about the professional repair of planar surface gantries of the type EXCM.
However, the costs of carrying out a repair must be considered in the case of larger defects.
Before carrying out a repair, the relevant chapter in these instructions must be read in full and followed consistently.
For reasons of clarity, these repair instructions do not contain all detailed information. The following documents should
therefore also be available while performing repair work on the planar surface gantry:
– Description of “mechanical installation”
Describes how to mount, install and dismantle the respective planar surface gantry. It can be found on the Festo
website (www.festo.com/sp).
– “Commissioning” description
Describes the functions, the electrical installation, the commissioning using the FCT, the operation, the control
principle and the procedure for error diagnostics for planar surface gantries. It can be found on the Festo website
(www.festo.com/sp).
– Spare parts documentation
Contains an overview of the spare and wearing parts as well as information on their installation. This can be found in
the online spare parts catalogue on the Festo website (www.festo.com/spareparts).
– “Tools and repair accessories” information brochure
Contains an overview of available assembly tools (e.g. lubricants, locking agent), special tools, schematic diagrams,
xtures, measuring devices, etc. The information brochure can be found in the online spare parts catalogue on the
Festo website (Tools and repair accessories.pdf).

– General lists.
Reference to further information.
Underlined, blue text indicates a cross-reference or hyperlink that you can click on in the PDF.
1.4 General safety instructions
Danger
Risk of fatal injury due to electric shock and uncontrolled movement of components.
– The planar surface gantry must be de-energised, depressurised and reliably secured against unauthorised
reactivation before the maintenance and repair work begins.
Caution
The planar surface gantry may only be repaired by authorised and trained persons in accordance with the
specications in the technical documentation and using original spare parts.
Installation and repair by unauthorised and untrained persons, repairs using non-original spare parts or without the
technical documentation required for installation and/or repair are dangerous and therefore not permitted.
Repairs must only be carried out in conjunction with these repair instructions and the respective operating
instructions for the device, as well as the documents listed in Chapter 1.1 on page 6.
Caution
Unintended switching on can trigger unexpected movements and cause bruises.
– Ensure that the unit is protected against restarting before any modication or maintenance work or inspections
are carried out. Loosened parts can make unexpected movements or fall off.
– Secure parts against accidental movements or move them into a safe end position.
Note
Observe the given tightening torques. If no special information is given the tightening torques given in the relevant
standard apply to the screws, bolts and nuts used.
Note the strength class of the screws, bolts and nuts!
Festo recommends use of LOCTITE 243 thread locking agent.
In the event of damage caused by unauthorised manipulation, improper use or use of non-original spare parts, all
warranty and liability claims against the manufacturer expire.
Instead of carrying out the repair yourself, your local Festo sales ofce offers the option of having the repair carried
out by Festo.
Components and equipment replaced during repair must be disposed of in accordance with the relevant local
environmental protection regulations.

1.5 Technical requirements
Note
The following instructions for safe and proper use must be observed:
– Observe the connection and ambient conditions specied in the technical data of the products and all the
connected components. The product can only be operated in compliance with the relevant safety guidelines if you
comply with the limit values and load limits (see enclosed documentation).
– The planar surface gantry must be in perfect technical condition.
– The planar surface gantry may only be operated in its original condition and without unauthorised modications.
– The planar surface gantry is designed for industrial use.
1.6 Standards and test values
Standards and test values which products comply with and full can be found in the “Technical data” sections of the
enclosed documentation.
2 General product description
2.1 Functional description
The EXCM-10 and EXCM-30 are compact planar surface gantries, whose slides can be moved freely in a 2-dimensional
space (X-Y-axis).
The slides are driven in position-controlled operation via two xed stepper motors. The motors and the slide are coupled
to a toothed belt. The toothed belt is guided via pulleys so that the slide can move to any position within the working
space. This drive concept results in a very low moving mass.

2.5 Type code
The features of a planar surface gantry can be determined with the help of the product labelling on the planar surface
gantry. The Festo logo and the product labelling are attached separately to the planar surface gantry. The product
labelling for both sizes is located on the drive cover. The order code describes the planar surface gantry’s features,
separated by a hyphen “-”.
A list and description of all possible equipment features of the planar surface gantry can be found in the data sheet, It
is available on the Festo website (www.festo.com).
