61 -- STEP MOTOR INDEXERS SOL 53SBNB860123 DUE 080598 POC Joan M. Smith, (301) 975-6458 WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued. The solicitation number, #53SBNB860123, is a Request for Quote (RFQ). The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 97-04. The associated Standards Industrial Classification Code (SIC) for this procurement is 5084, and the small business size standards for employees is 500. This procurement is not set aside for small business. The National Institute of Standards and Technology (NIST) has a requirement for Step Motor Indexers, identified as Contract Line Item Number (CLIN) 0001, quantity -- 250 axes each. CLIN 0002 -- Option for 25 axes to be exercised within 6 months ARO. CLIN 0003 -- Option for 25 axes to be exercised within 12 months ARO. CLIN 0004 -- Option for 25 axes to be exercised within 18 months ARO. CLIN 0005 -- Option for 25 axes to be exercised within 24 months ARO. Provide a price per unit. Background -- The NIST Center for Neutron Research (NCNR) is a national facility dedicated to the use of neutrons for materials research and basic science. With 18 operational neutron spectrometers under construction, this facility provides the nation with its most versatile capability for neutron based research. The NCNR has identified the need to modernize the computer-based stepper motor systems which control the position of the many movable components on each spectrometer. NIST has determined that the next-generation motor control system for each spectrometer will be based on a VME bus architecture where the motion control processors will receive the position feedback and direct the control of the step motor driver amplifiers under the control of the VME host computer. Towards this design goal NIST intends to purchase from a manufacturer's standard inventory, a number of multi-axis motor control indexer boards in a single width, 6U size VME form factor. These units are required to support a variety of standard motion control functions, process feedback from incremental position encoders, limit switches, home switches, and digital or analog I/O channels and provide a standard TTL-compatible STEP /DIRECTION control interface to step motor drivers. Specifications -- The step motor indexers shall meet the following specifications: (1) multi-axis (4 axes or more per card) VME motor indexer board, 6U size. This product shall be part of the manufacturer's standard inventory; (2) support dual port VME addressing; (3) support VME bus interrupts for specific operating conditions, especially on "in-position", "limit", "done"; (4) status and position registers available for fast update over VME bus (preferrred); (5) 500kHz step output pulse rate minimum bandwidth (TTL); (6) motor driver interface shall be TTL compatible: STEP, DIR, REMOTE, ENABLE/SHUTDOWN, DRIVE FAULT (input) and REMOTE STANDBY for power reduction (preferred); (7) support trapezoidal, cosine velocity profiles; (8) support open-loop (no encoder feedback) position moves; (9) support multi-axis contouring moves; (10) support single axis or simultaneous multi-axis MOVE, STOP or E_STOP (KILL) commands; (11) two separate end-of-travel limit switch inputs and a home switch input per axis; (12) two-phase quadrature incremental encoder input with an index channel input per axis, 2MHz minimum bandwidth. Shall be able to support single-ended or differential inputs. Shall support TTL compatible logic such as open collector, TTL or line driver encoder outputs. Shall provide a +5VDC supply voltage for encoder; (13) support encoder position based moves (i.e., closed loop), including position error correction mode (position maintenance) and stall/slip detection; (14) support homing routines based on either the HOME switch alone, or based on the HOME switch input and the encoder index channel; (15) provide digital and or analog input/output channels whose function can be user defined; and (16) interface modul to facilitate connection between VME indexer and motor driver and encoder/limit switch inputs (preferred). Delivery is required within 12 weeks ARO. Delivery location is NIST, Building 301, Receiving Room, Gaithersburg, Maryland 20899, The FOB point shall be Destination, Gaithersburg, Maryland. The following FAR provisions apply to this solicitation: FAR 52.212-1 Instruction to Offerors-Commercial; FAR 52.212-2, Evaluation-Commercial Items. Evaluation Criteria to be included in paragraph (a) of provision FAR 52.212-2 are as follows: (1) Technical Capability to meet or exceed the Government's requirement. (2) Past Performance. This will be based on the offeror's demonstrated experience with the VME based step motor control. Offeror's should include recent references (within the last 3 three years) of installations of the proposed unit type with step motor control systems of 20 axes or more. The list should include the name, address, and phone number of the local contact; and (3) Price. Technical evaluation criteria, when combined, are significantly more important than price. Evaluation of the quote will be inclusive of all options. Offerors shall address all requirements in this combined synopsis/solicitation, and shall provide clear evidence of understanding of the Government's requirement and the ability and willingness to comply with the Government's specifications of need. Failure to address a specification/ requirement will be construed by the Government as inability to meet the need or the offeror's taking exception to it. All vendors are to include with their quotes, a completed copy of provisions 52.212-3, Offeror Representations and Certifications-Commercial Items, which may be downloaded from http://www.nist.gov/admin/od/contract/repcert.htm. The clause at 52.212-4, Contract Terms and Conditions-Commercial Items, applies to this acquisition. The clause at 52.212-5, Contract Terms and Conditions Required to Implement Statutes or Executive Orders -- Commercial Items, applies to this acquisition, including subparagraphs: (1) 52.203-6, Restrictions on Subcontractor Sales to the Government, with Alternate I; (3) 52.219-8, Utilization of Small Business Concerns and Small Disadvantaged Business Concerns ; (6) 52.222-26, Equal Opportunity; (7) 52.222-35, Affirmative Action for Disabled Veterans and Veterans of the Vietnam Era; (8) 52.222-36, Affirmative Action for Handicapped Workers; (9) 52.222-37, Employment Reports on Disabled Veterans and Veterans of the Vietnam Era; (10) 52.225-3, Buy American Act-Supplies; (15) 52.225-21, Buy American Act-North American Free Trade Agreement Implementation Act-Balance of Payments Program; and Department of Commerce Agency-Level Protest Procedures Level Above the Contracting Officer, which can be downloaded from the NIST Web Page at http://www.nist.gov/admin/od/contract/protest.htm.
