Universal rotary unit
Universal flat rotary unit with absolute encoder and electric brake as well as optional increased protection class (IP54)

Advantages – Your benefits

  • Integrated torque drive
    for high torque and flexible use by controlled position, velocity and torque
  • Extremely flat design
    for minimal interfering contours and for use in confined spaces
  • With absolute position measurement system
    Less programming effort and time saving when commissioning and in operation
  • Optionally certified safety devices according to SIL2/PLd
    with the DRIVE-CliQ interface for applications with high requirements in the area of machine safety
  • Optional electric brake
    for maintaining the position in downtime
  • Large center bore
    for feed-through lines and media hoses
  • Versatile actuation options
    for simple integration into existing control concepts using different external third-party controllers (e.g. Bosch Rexroth IndraDrive or Siemens SINAMICS)
  • NEW:
    Due to the single cable technology HIPERFACE DSL®, it saves costs, requires less space and is easy to implement.

Options and special information

  • Using the electric holding brake
    The installed brake is only designed to be used as a holding brake. Consequently, it may only be actuated when stationary. Use as an operating brake is not permitted and significantly increases wear.
  • Design with IP54 option
    With the IP54 option, increased friction is caused by the seals (top and bottom). These have a minor effect on the cycle time in a normal positioning process (< 360°). In this case, the ERT can be designed with the IP54 option in the sizing assistant on the homepage. When used as a rotary drive (continuous rotary movement), the friction of the seals (top and bottom) reduces the available input torque. In this case, additional factors must be taken into account during the design. Please ask for details.
  • UL certification
    The electrical ERT rotary module is partially available with UL certification (certified according to US and Canadian regulations) on request. Please contact us.
  • Certified encoder system
    The encoder system with the DRIVE-CLiQ interface is certified according to SIL2/PLd. This means that even demanding applications with high requirements in the area of machine safety can be implemented. Please contact us for further information.
  • HIPERFACE DSL® encoder interface
    The HIPERFACE DSL® encoder interface is a purely digital motor feedback protocol. Due to the single cable technology, it is possible to save costs, it requires less space and it is easy to implement. This interface is currently only supported by the Beckhoff AX8000 drive controller. Please contact us if you would like to use our product with other controllers that support the Hiperface DSL® interface.
