3.2 Operating principle

Two fixed stepper motors drive a toothed belt arrayed in an H shape.
The toothed belt moves the Y-axis (traverse) and the slide located on the Y-axis (traverse) in a 2-dimen
sional space. A controller calculates the position of the slide. The controlled interaction of the motors
results in the corresponding movement of the slide.

3.3 Permitted mounting position

Warning

The use of the planar surface gantry without a motor brake in a mounting position other
than horizontal can result in uncontrolled movements of the attached load.
Freely movable loads can result in injury to people and damage to the peripherals of the
planar surface gantry.
 Use a planar surface gantry without motor brake (EXCM-30-…-ST-…) exclusively in a

horizontal mounting position.

4.3 Installation

Note

If there are temperature differences between the product and the mounting surface:
 Adapt the temperature of the product to the temperature of the mounting surface.

Observe the permissible ambient temperatures
(è A.5 Operating and storage conditions).

Note

The planar surface gantry is delivered from factory with a backlash-free setting.
 When mounting the planar surface gantry make sure that it is not distorted, because

if it is, it can change this setting.

 Follow the subsequently described procedure for attachment of the planar surface

gantry to avoid tension.

Caution

Inappropriate mounting material can cause the planar surface gantry to loosen and fall
down if the mounting position is not horizontal, which can result in injuries.
 Make sure that the mounting material used (socket head screws of the profile

mountings) ensures sufficient strength in combination with the mounting surface.

If mounting kits are covered by the Y-axis (traverse), this can be moved manually. To do
this, remove the motors (è 4.4.1 Mounting/dismantling motor) or release the holding
brake.

4.5.2 Setting end stops of the Y-axis

To reduce the risk of collisions between attach
ment elements and parts of the planar surface
gantry, the stroke of the Y-axis can be adjusted
accordingly by means of adjustable end stops
(threaded pins).
Various thread pin pairs are included in the scope
of delivery.

The positioning accuracy of the product is dependent on a correct homing. This is only
possible with a hard, mechanical stop. Homing on the motor side should be preferred.

è Only use the end stops included in the delivery (threaded pins) – do not use elastic

materials.

7.1 Safety instructions

Warning

Unexpected movement of the product in case of break of the toothed belt.
Risk of injury from electric shock, impact, crushing.
 Regular test of the toothed belt on signs of wear. Contact our service department if

there are signs of wear.

Warning

Unexpected movement of the product.
Risk of injury from electric shock, impact, crushing.
 Before working on the product, switch off the power supply and secure it against

being switched on again.

 If a toothed belt breaks in combination with a mounting position of the planar sur

face gantry that is other than horizontal, the work mass will fall down.

7.2 Cleaning

Note

Only clean the product in exceptional circumstances by using non-abrasive cleaning
agents and a soft cloth.
Do not clean the guide elements (e.g. guide rails).

7 Maintenance

Festo – EXCM-30-EN – 1605b – English 31

7.3 Lubrication

The product is lubricated initially upon delivery. Subsequent lubrication is only required if

Caution

Crushing due to axis movements of the product.
 Slowly move or travel the Y-axis (traverse) and the slide of the Y-axis.
 Make sure that no one is located in the movement area during the axis movements.

7 Maintenance

32 Festo – EXCM-30-EN – 1605b – English

Note

For motors with holding brake, it is not possible to manually move the Y-axis (traverse)
and the slide of the Y-axis.
The product must be connected and ready for operation.
 Move the Y-axis (traverse) and slide of the Y-axis in manual override.

Observe the documentation (è description EXCM-… “Commissioning”).

Greasing the guide rail

1. Thinly lubricate the guide rails of both axes (è Fig. 7.1) with grease.

2. Move both axes repeatedly over the entire stroke.

Greasing the bearing guides

1. Grease the marked bearing guides (è Fig. 7.1) on both sides at all lubrication holes.

2. Move the slide the complete travel distance during greasing in order to distribute the grease evenly

inside.

7.4 Repair

If you require support for repairs:
 Please contact your regional Festo contact person.
