Electrical rotary unit with torque motor and angle of rotation > 360° as well as the optional pneumatic brake and rotary feed-through, and if desired increased protection class (IP54)
Description
Advantages – Your benefits
- Integrated torque drive
for high torque and flexible use by controlled position, velocity and torque - Large center bore
for feed-through lines and media hoses - Compact design
for minimal interfering contours and for use in confined spaces - Easy system integration
by standard encoder interface (Sin/Cos) - Versatile actuation options
for simple integration into existing control concepts using different external third-party controllers (e.g. Bosch Rexroth IndraDrive or Siemens SINAMICS) - Optional pneumatic holding brake
for maintaining the position in downtime
Options and special information
- Using the pneumatic 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. - Cycle time design with pneumatic holding brake
The piston fill time of a pneumatically operated holding brake is between 100 and 200 ms depending on the size of the rotary module. This time is already permanently stored in the standard parameter sets for the Siemens and Bosch Rexroth controllers. - Electric and pneumatic rotary feed-through
The ERS with rotary feed-through may be operated with a max. speed of rotation of 250 RPM due to the integrated seals and the slip ring. The current load per signal line (pin 4 on the M8 connector) is 2 A. The collected power supply via pin 1 of the M8 connector may not exceed 4 A.
