Features:

  • Independent multi-axis control: Positions up to three axes independently.
  • Open- or closed-loop operation: Uses closed-loop positioning or open-loop limit-switch control.
  • On-module program storage: Holds traversing programs and performs position control on the module.
The Siemens 6FM1726-3BA00 WF726B positioning module keeps the positioning task on the module, helping relieve the main SIMATIC S5 CPU of complete position-control work.

Its WF 726 operating concept supports independent axis positioning through either closed-loop control or open-loop limit-switch control. The selected machine implementation must retain the intended feedback and control arrangement.

Traversing programs are stored directly on the positioning module, so a service request should match the complete 6FM1726-3BA00 module identity before configuration or program recovery is considered.

Apter Power supports document review, quotation, and procurement for the Siemens 6FM1726-3BA00 WF726B Positioning Module.

Important Notice: Review the complete model and installed configuration before using any documentation for service work.
  • Select by the complete 6FM1726-3BA00 code, not by a shortened WF-series reference.
  • Use the WF726B designation together with the complete model when comparing the removed unit.
  • Stop selection when the module marking or connector arrangement does not match the installed assembly.
  • arrangement before removing 6FM1726-3BA00 from the equipment.
  • Return the module only to the documented control-system position for the removed assembly.
  • Use qualified electronic-module handling and site-approved ESD controls during replacement work.
  • kaRecord the connector arrangement before removing 6FM1726-3BA00 from the equipment.
  • Return the module only to the documented control-system position for the removed assembly.
  • Use qualified electronic-module handling and site-approved ESD controls during replacement work.
  • Start the service check with the complete 6FM1726-3BA00 marking and WF726B designation.
  • Compare the removed unit’s connector arrangement with the installed-system record before a sourcing decision.
  • Pause the replacement review if the physical interface or installed position cannot be confirmed.
  • 6FM1726-3BA00 is identified as a Siemens WF726B positioning module.
  • Use it only where the removed assembly and installed equipment record identify the same complete model.
  • For similar WF-series hardware, keep the request within the documented connector and system-position boundary.
Description

6FM1726-3BA00 is the Siemens WF726B positioning module identified by the complete code on the module nameplate. Keeping the full designation with the equipment record distinguishes this legacy assembly from similar WF-series hardware.

For a machine repair, 6FM1726-3BA00 should be matched to the removed module’s connector arrangement and installed control-system position. A related board can look similar while presenting a different interface at the machine.

Using the complete 6FM1726-3BA00 identifier in a sourcing request keeps the enquiry tied to the correct legacy assembly and gives maintenance and procurement teams a clear basis for technical review.

Alternative Names

Technical notes
The WF726B identification on 6FM1726-3BA00 defines a legacy Siemens positioning-module variant, so connector layout and the installed machine position are the critical boundaries. A replacement decision should stop when either record is unavailable, because a related WF-series module can share the family name without proving the same physical interface or controller role.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What positioning work can Siemens 6FM1726-3BA00 perform in a legacy machine-control system?
Siemens describes the WF 725/WF 726 family as positioning modules capable of controlling up to three axes independently. Confirm the installed machine uses the WF 726B configuration before using this function description for the exact 6FM1726-3BA00 module.
Why should the traversing-program record be retained before replacing 6FM1726-3BA00?
The WF 725/WF 726 documentation states that traversing programs are stored on the positioning module. Retain the machine’s existing program and commissioning records before removal so the replacement can be checked against the established motion sequence.
A machine has lost positioning on one axis. Does that prove 6FM1726-3BA00 has failed?
No. The module can control axes independently, so a single-axis issue should be assessed against that axis’s feedback, drive circuit, wiring and machine data before condemning the complete 6FM1726-3BA00 module.
What must be checked when installing a 6FM1726-3BA00 in place of a removed WF 726B?
Check that both required plug connections are present and that the module is installed in the correct SINUMERIK/SIMATIC S5 location. Siemens identifies the WF 725B/WF 726B arrangement as requiring two plug connections.
Why is the PLC rack and addressing information needed for a 6FM1726-3BA00 replacement?
WF positioning modules exchange user programs, machine data, and start/stop signals through the S5 bus and are addressed as I/O modules. The replacement must therefore be checked against the original rack position and addressing record, not only the front-panel part number.
Can the same 6FM1726-3BA00 application be assumed to use closed-loop positioning?
No. The WF 725/WF 726 family supports closed-loop positioning and open-loop limit-switch control. Confirm the installed machine’s feedback and control method before changing motion settings or approving a replacement.
