2. Basic safety notices
This chapter serves to ensure the safety of everyone working with the linear tables HT-L and those who assemble, install,
operate, maintain or disassemble them. Non-compliance with the following information results in dangerous working
conditions.
WARNING!
2.1 Intended use
The linear tables HT-L combine guiding and drive functions in the one compact unit. They are designed for the precise
positioning in terms of time and location of fixed mounted loads within an automated system. They are specifically ideal
for applications requiring high dynamic responses and precision. Also, with these linear tables large travel distances can be
realised.
Linear tables HT-L may only be installed horizontally and may only be used for the intended purpose as described:
|All HT-L linear table sizes are subject to performance limits (see catalogue „Linear Axes and Axis Systems HX”).
These performance limits may not be exceeded during operations.
|The linear tables HT-L must not be operated in potentially explosive atmospheres.
|The linear tables HT-L may only be used and operated indoors.
|The linear tables HT-L form part of a complete system. Personal safety must therefore be safeguarded beyond the
concept for this complete system.
|Proper use of the linear tables HT-L includes observing the assembly instructions and following the maintenance and
repair specifications.
|Use of the linear tables HT-L for any other purpose shall be considered improper use.
The linear tables HT-L are delivered as a system (guiding/drive). Therefore observe the whole documentation for this system.
The provided documentation may vary depending on the linear axis type.
2.2 Reasonably foreseeable misuse
Linear tables HT-L must not be operated:
outdoors
in potentially explosive atmospheres
2.3 Conversions and modifications
Conversions or modifications to the linear tables HT-L are not permitted!
2.4 Residual risks
During normal operation, there are no residual risks associated with the linear tables HT-L because they form part of the
complete system and the operator must safeguard personal safety beyond the concept for this complete system. Warnings
about risks that may arise during maintenance and repair work are provided in the relevant chapters.

3.4 Functional description
The linear motor axes HT-L are based on an aluminium basic profile with integrated linear guideways. These both absorb the
forces exerted by the weights, accelerations, and processes and provide precise guiding for the carriage. The axis is driven by
a linear motor.
The linear motor consists of two components, the forcer (primary part) with coils and the stator (secondary part) with perma-
nent magnets. The coils carrying alternating current generate a magnetic field that changes over time and interacts with the
steady magnetic field of the stator. The resulting force is used to generate linear motion.
The motor is energized via a drive amplifier in such a way that the carriage of the linear motor axis executes precisely the
movement that is predetermined, for example, by a higher-level control system.

4.5.1 HIWIN-MAGIC
The HIWIN-MAGIC distance measuring system is used in the linear tables HT-L for incremental distance measurement. The
output signals can be either analogue or digital. The HIWIN-MAGIC distance measuring system consists of the encoder (Fig.
4.4) and the magnetic scale (Fig. 4.5) as the measurement standard. It is assembled prior to delivery.
Fig. 4.4 MAGIC encoder Fig. 4.5 MAGIC magnetic scale
The measuring scale of the magnetic measuring systems may not be subjected to any strong magnetic fields
(keep it well away from permanent magnets!). Strong shocks (e.g. hammer blows) can also damage the mag-
netization of the measuring scale. The system is not suitable for environments where there is magnetic dust
(e.g. graphite dust). These things can falsify the encoder signal or damage the distance measuring system.

4.5.2 TTK701)
The TTK70 distance measuring system is used in the linear tables HT-L for absolute position determination, without reference
run. The position determination is magnetic with very high resolution. The sensor board which is aligned with the measuring
level is equipped with Hall sensors on two parallel tracks. Their arrangement corresponds to the division of the magnetic
scale into an incremental and an absolute component. To calculate the absolute position values during operation, the
encoder first detects the absolute starting position when the linear motor is started via the Manchester encoding. Then all
further actual positions of the drive are determined via the incremental position on the magnetic track or via sine/cosine
signals. The measuring system is integrated inside the axis in order to save space. The interface for the electrical connection
is located on the side of the carriage. The system is integrated via the HIPERFACE®interface.

Information on connection and pin assignment can be found in Section 6.6.2.2
For professional commissioning and integration into the system with the HIPERFACE®interface, please refer to the manufac-
turer’s documentation.

Danger from electrical voltage!
Before and during assembly, disassembly and repair work, dangerous currents may flow.
XBefore connecting the electrical power supply, ensure that the linear table is correctly earthed via the PE
rail in the switch cabinet!
XNever loosen electrical connections when energized. In unfavourable cases, electric arcs can form, caus-
ing injury and damage to contacts!
XOnly qualified personnel may work on electrical installations!
XHeed the assembly instructions for the other system components (e.g. linear motor, drive)!
DANGER!
Linear tables HT-L are equipped with an interface for motor and encoder cables. This is located on the side of the carriage.
The self-locking quick fasteners it features provide a fast and easy way of connecting the cables – without the need for
tools. There are four different options for the connector configuration to suit the installation conditions and how the cables
need to be routed, see Fig. 4.9.
To ensure that the supply cables are carried safely, linear tables HT-L with a stroke of up to 4,000mm are available with the
option of generously dimensioned energy chains. They are extremely compact and save space when used with the axis. The
configuration of the energy chain depends on the chosen connector orientation, see Fig. 4.9.

4.8 Energy chain
Optional energy chains are available for the linear tables HT-L. The chains can be installed on either the right or the left and
is based on the selected connector position. The generously dimensioned energy chains provide enough space for the supply
cables to be carried safely. They are extremely compact and achieve space savings when integrated into the system as a
whole.
For details of the energy chain type and size, please see Table 4.6.

The upper run is self-supporting but there is a surface for the lower run that supports the energy chain as it unrolls. To
prevent the cables and hoses from riding over each other, there is a partition in every second link. The connecting pieces are
of a rigid design. Strain relief combs are fitted at both ends so that the cables and hoses can be secured with cable ties. To
ensure that the energy chains are handled correctly, and that the cables and hoses are installed and secured properly, please
observe the assembly instructions from the energy chain manufacturer.
General notes:
|For details of suitable motor and signal cables, please refer to the operating manual from the motor manufacturer.
|Observe the minimum bending radii (industrial standard 8 × D) specified for the cables and hoses, and the associated
service life that is to be anticipated.
|In the case of shielded cables, make sure the shields are resistant to bending.
|Low-friction and abrasion-resistant cable/hose sheaths should be used.
|To prevent cables and hoses with different outer sheaths from bonding, separate them with partitions.
|Ensure twist-free installation of cables and hoses.
|Leave enough spare room (10 to 20%, at least 1mm) all the way around the cables and hoses, and allow for the
lateral expansion that occurs when hoses are pressurised.
|Make sure that the weight is distributed evenly/symmetrically. Ideally, heavy cables and hoses should be positioned at
the outer edges.
|Provide strain relief for cables and hoses at both ends so that they are located in the neutral zone when the energy
chain is in the extended position and can move freely within its radius.
|In the case of high acceleration values or if the cables have a wide variety of diameters, use additional partitions
where applicable.
|Observe the maximum additional load from cables and hoses that is permitted based on the stroke (see Fig. 4.10).
