This manual and the warnings attached to the LV linear slides only highlight hazards that can be predicted by Gimatic. Be aware they do not cover all possible hazards. Gimatic shall not be responsible for any accidents caused by the misuse or abuse of the device by the operator.
Gimatic - LV Electric Linear Actuators www.gimatic.com 1.1 General safety The following points must be understood and adhered to at all times: • Equipment operators must read the User Guide carefully and make sure of the correct procedure before operating the LV linear actuators.
3 PRODUCT OVERVIEW 3.1 About Gimatic's LV actuators The Gimatic LV actuator is a recirculating ball bearing slide equipped with a 3-phase, brushless, DC, permanent-magnet motor designed for direct-drive, high-precision and high-dynamics applications. High efficiency and performance of Gimatic's ML linear motors meet a lightweight aluminium slide which provides a prismatic guide for the motion of the slider (anti-rotation), a heat dissipation functionality and high stiffness in several directions.
LV actuators can be combined in order to create multiple axis systems. Furthermore for all those applications requiring longer strokes and/or higher stiffness along the entire stroke, Gimatic linear actuators are also available as linear guides (LVP25 and LVP40). These guides can be combined with LV actuators to create more complex structures (i.e.

Gimatic - LV Electric Linear Actuators www.gimatic.com 4.2 Electric linear slides 4.2.1 Application A LV linear actuator is based on a tubular linear motor that provides relative motion between the slider and the stator. In a single axis system the LV part hosting the motor's stator is typically fixed to an external frame while the slide hosting the motor's slider interacts with the load (directly or by means of gripper or some other tools).
A counter balance device should be considered in order to compensate the load statically. Gimatic manufactures a spring compensator that can be mounted laterally on LV devices. A brake is recommended for most applications but must be used to prevent damage in applications where the load drops immediately after power is removed.
4.3 Servo drive Gimatic does not manufacture servo drives since the LV actuators are compatible with most 3-phase, AC, brushless servo drives available on the market. The following is a list of some of the commercial drives tested over time.
The linear encoder is used to provide position feedback to the servo drive to allow for accurate control of the LV actuators. Gimatic manufactures an incremental ABZ encoder with RS-422 output signal for two different resolutions: 25 μm (SE9ABZ1) and 10 μm (SE9ABZ1-HR). The choice of what encoder best fits the application also depends on the maximum speed expected: the higher the resolution, the lower the maximum speed.

4.5 Sensors Hall sensors In the same package of the incremental encoder transducer, Gimatic manufactures a sensor with simulated HALL sensors output. This accessory is especially suited for vertical applications where initial movement usually required for the wake and shake procedure is not allowed.
Page 17
In addition to end stop sensors, it is recommended to incorporate end stop bumpers to absorb and stop the movement in the case of over travel. Gimatic can provide both end stop sensors and bumpers, please contact your local area Gimatic's distributor.
Page 18
Gimatic - LV Electric Linear Actuators www.gimatic.com LV linear actuators are provided with special brackets allowing the usage of magnetic proximity switches as end stop and home sensors. Since sliders of LV40 actuators show a much stronger magnetic field respect to LV25 models, inductive proximity switches can also be used for LV40 actuators only that can be mounted using optional brackets.

Gimatic - LV Electric Linear Actuators www.gimatic.com Operating Environment The temperature of the operating environment is critical when determining the appropriate motor model to use. When the motor is producing force, it will produce a temperature rise above ambient. The higher the temperature of the motor operating environment, the hotter the motor will become under the same duty cycle.

Gimatic - LV Electric Linear Actuators www.gimatic.com 5.3 Static thrusts The maximum thrust the linear actuator can exert depends on the slider portion inserted in the motor. The following graphs show the variation of the maximum force that can be exerted by the motor under static conditions.

Gimatic - LV Electric Linear Actuators www.gimatic.com 6 INSTALLATION 6.1 Unpacking WARNING: Tubular motor shafts contain powerful permanent magnets. People with a pacemaker, AICD or similar medical devices should maintain a minimum distance of 30 cm from the shaft WARNING: The shaft emits a very strong magnetic field. Always use caution when handling.
2. electrical wiring between the encoder and servo drive (on an incremental encoder, inversion of one of the quadrature signals is sufficient); 3. software configuration on the servo drive. In case of first installation or replacement of Gimatic's position transducers and/or sensors (SE9 series), please refer to the following steps: •...
Several mounting interfaces are available to connect LV actuators with other LV units, LVP guides, gripping and rotating devices of Gimatic's Mechatronics series. An overview on some mounting solutions is summarized here in the following pictures but many others are possible. Please refer to the accessories section for a complete list of available interfaces and ordering codes.
DANGER: The actuator must be grounded to prevent the possibility of electric shock during motor operation. Any Gimatic’s ML motor is provided with a 30 mm log flying cable output. The power supply and temperature signal cable can be directly connected to a servo drive by means of an extension cable and either EN175000 7-pole circular connectors (for 70 V BUS voltage) or M23 6 pole circular connectors (for 325 V BUS voltage).
Gimatic - LV Electric Linear Actuators www.gimatic.com 6.3.2 Sensors Connect the sensors, such as home switches and dead stops, to be used to the servo drive as specified in the sensor and servo drive documentation. 6.3.3 Electromagnetic Compatibility (EMC) While the ultimate responsibility for a system’s EMC compliance lies with the system builder, the LV design provides good EMC performance as a system component.
