2.1 Proper use
The rotary table is a rotating drive and guide system for the exact, time-controlled positioning of
permanently mounted loads, such as system components, in an automated system.
Rotary tables are designed for installation and operation in any position, but do not have a
parking brake. The loads to be moved must be fixed into position on the rotor.
The rotary tables must not be used outdoors or in hazardous areas where there is a risk of
explosions. Rotary tables may only be used as described for the intended purpose.
Rotary tables may only be operated within their specified performance limits (see “Rotary
tables” catalogue).
The assembly instructions and the maintenance and servicing instructions must be
complied to ensure the intended use of the rotary tables.
Any other use of the rotary tables is considered improper use.
Only original spare parts from HIWIN GmbH may be used.
2.2 Reasonably foreseeable misuse
Rotary tables must not be operated:
Outdoors
In areas where there is a risk of explosion
2.3 Conversions or modifications
Conversions or modifications to the rotary tables are not permitted!
2.4 Residual risks
No residual risks emanate from the rotary tables during normal operation. Dangers that may
arise during maintenance and servicing are specified in the respective chapters.

3.1 Application
The rotary table is a rotating drive and guide system for the exact, time-controlled positioning of
permanently mounted loads, such as system components, in an automated system.
Rotary tables are designed for installation and operation in any position, but do not have a
parking brake. The loads to be moved must be fixed into position on the rotor.

4 Crossed roller bearings 9 Seal 14 Motor housing
5 Rotor 10 Lower housing cover 15 Seal
3.3 Functional description
The rotary table is driven by a 3-phase, permanently excited torque motor. The integrated
bearing absorbs loads and torques and transfers them to the machine bed. The integrated
distance measuring system provides a standardised sin/cos-1 VSS output signal. The rotary
table is operated with a suitable servo drive.

For information on the torque motors suitable for the HIWIN rotary tables, please refer to the
“Torque motors DMR, TMRW” assembly instructions. These are available for download at
www.hiwin.de.
3.5 Protective plate (option)
The sealing of the torque rotary tables consists of a labyrinth and sealing lips inserted into it,
so-called V-seals. If the rotary table is exposed to abrasive liquids, such as in grinding
machines, then this liquid comes into contact with the sealing lips and can damage the sealing
lip and its drainage surface.
In order to achieve a sufficient service life of the sealing even when abrasive liquids are used, a
stainless steel protective plate is placed on the gap of the labyrinth. This protective plate
provides reliable protection against the ingress of liquids when the rotary table is mounted
horizontally.
Only in the case of overhead and wall mounting should the protective plate not be used, as it
would collect additional liquid and dirt particles in this position.
Note:
The outer diameter of the rotary table increases by 5 mm due to the protective plate.
Fig. 3.2: DMSX – version with optional protective plate

Description of rotary table
Rotary tables DMS and DMN TM-02-4-EN-2202-MA Page 12 of 32
For overhead mounting and for wall mounting combined with abrasive liquids, HIWIN rotary
tables are supplied with a sealing air preparation.
For the additional sealing air, 5 of the radial M4 threads (see Fig. 3.3) are sealed with the
enclosed grub screws and the sealing air is connected through the 6th threaded hole. The
matching push-in fitting is enclosed.
Hose diameter: 4 mm
Air pressure: 0.2 to 0.5 bar

3.6 Parking brake (option)
Note:
The parking brake (clamping element) is only used to clamp the stationary shaft in continuous
operation.
Note:
The parking brakes are mounted under the housing cover as standard. This changes the
dimensions of the rotary table.
Depending on the type, the rotary tables are equipped with a pneumatic parking brake. The
brakes used are emergency-activated, i.e. they are activated without pressure. Parking brakes
are currently available for the DMS3 series and DMS7 series.

3.6.1 Holding torques
If no supplementary air is connected, the rear valve (“Close”) must remain open.
The holding torques are given in Table 3.2. Without application of air, the parking brakes are
closed. The holding torque can be increased by adding air to the rear valve ("Close"), see Fig.
3.5.

Holding torque without additional air 114 Nm 114 Nm 336 Nm 336 Nm
Holding torque with additional air 210 Nm 140 Nm 600 Nm 400 Nm
3.6.2 Connection
Note:
To minimise reaction time, the valves should be placed as close as possible to the parking
brake. In addition, quick exhaust valves can shorten the reaction time.
The parking brake must be controlled with a 3/2 or 5/2-way valve, as shown in Fig. 3.5. The
valves must have a minimum nominal size of G 1/8. The hose connection must not fall below a
minimum diameter of 6 mm.
Fig. 3.5: Pneumatic connection of the parking brake
3.6.3 Commissioning
The function of the parking brake is checked by HIWIN before delivery. Before commissioning
the rotary table, it must nevertheless be checked to ensure that
The parking brake is open (check by turning the shaft manually)
There is no dirt (oil or grease, small solids) between the clamping surfaces
