Supports tension, position, winder, coiler, synchronized-motion and positioning control tasks.
Technical Summary
6DD1606-0AD0 is the Siemens SIMADYN D T400 technology module. Siemens documents sampling times down to 100 microseconds for demanding open-loop and closed-loop drive functions.
The module is intended for SIMOVERT MASTERDRIVES 6SE70/71, SIMOREG DC-MASTER 6RA70 and the SRT400 technology subrack. Its application program, communication option and installed connectors remain part of the replacement boundary.

Features
Provides dual-port RAM coupling to the MASTERDRIVES base control board.
Includes serial communication choices for service, USS or peer-to-peer use according to the configured interface.
Can operate in an SRT400 with a second T400 or an approved MASTERDRIVES communication board.
Compatibility
- Confirm the complete 6DD1606-0AD0 label, board release, installed drive family and electronics-box or SRT400 position.
- Archive the STEP 7/CFC project, parameter set and any user-specific T400 application before removing the board.
- Match encoder types, serial interfaces, communication board and terminal hardware to the installed design.
- Do not substitute a preprogrammed application variant solely because it uses the same T400 hardware format.
Replacement
- Isolate the drive, observe the documented discharge time and use ESD controls before handling the module.
- Photograph all plugs, encoder connections, communication boards and switch or jumper positions.
- Restore only the approved project and parameter record, then test each affected control loop at a controlled operating point.
- Retain the final hardware identity, software checksum and functional-test evidence in the maintenance record.
FAQ
What project files should accompany a 6DD1606-0AD0 enquiry?
Provide the STEP 7/CFC project, parameter backup, installed drive model, communication board and clear board-label photographs.
Can a programmed T400 be replaced from the hardware number alone?
No. 6DD1606-0AD0 can carry an application-specific program, so the software project and machine function must be identified.
What encoder evidence reduces commissioning risk for 6DD1606-0AD0?
Record encoder type, supply, signal standard, resolution, zero-pulse use, connector pinout and the assigned T400 interface.
What should be checked when a T400 control loop becomes unstable?
Review feedback quality, scaling, sampling configuration, communication status and the approved controller parameters before replacing hardware.
What proves a replacement 6DD1606-0AD0 is ready for service?
Confirm the correct project, clean diagnostics and stable response of every affected loop through the approved operating range.
