- Description
- The purpose of this modification is to incorporate uploaded specifications and to extend the responses due date to July 3, 2002. RF Plasma Spray Controlled Motion Manipulator This request is for a new motion control system, we do not wish to change any existing bearings, seals, belts or pulley hardware. This is not a system upgrade, but rather one-to-one replacement of existing, antiquated equipment. Please only accept quotes to replace the programmable logic controller (PLC), operator interface display, servo amplifier, and servomotors. The replacement PLC, operator interface touch screen display and servo amplifiers should be all mounted in a 19-inch rack mountable NEMA 12 class enclosure. The enclosure should be approximately six feet tall. The enclosure should have a smoked polycarbonate type of front viewing door, and a closeable door on the back. The display should be mounted in the front of cabinet, with approximately a 10" screen for good visibility from short distances. The servomotors will be installed on the target manipulator and will be connected to the cabinet by cables, from a distance of approximately 25 feet. The rotation servomotor adapts to an Indiana Power Transmission Sys. Inc. Model: HQD-B-56C reduction gear box. Rotation should be capable of 0 to 100 RPM. The translation servomotor has a 0.1875 inch keyed slot and shaft that fits a pulley with a 0.55 inch inside diameter. Shaft should be about 1.75 inch length from mounting surface. The translation speed should be capable 0 to 2 inch per second. The PLC will be utilized to control two modes of operation; 1) Mandrel mode: controls rotation and translation of a round mandrel attached to a 2.5 inch diameter water cooled sting shaft that is manipulated inside a low-pressure vacuum chamber. 2) Table mode: controls a flat tabletop target in an X-Y fashion. It utilizes rotational motion to index the table in the Y direction and translates the same way as in the Mandrel mode. The system only operates in one mode at a time. If the sting is set-up with a mandrel then "mandrel mode" will be selected, if the sting is set-up with the X-Y table then "table mode" should be selected. These are two separate modes of operation. The display will be capable of accessing the program information in the PLC and be able to create multiple schedules of motion, and be able to store and recall them from that same display. The display will replace existing displays and provide motion speed and position (actual speed and RPM, not set point values) for both axes, and both modes. A remote manual jog switch is to be provided, that can be operated from 25 feet away, at the chamber location. The jog switch will provide manual rotation and manual translation control for both modes of operation. The system will be capable of operating in a continuous mode, or running a preset number of cycles for both table and mandrel modes. The system shall be pre-assembled in the cabinet prior to delivery to the facility. The servomotors shall be adapted to the existing hardware upon delivery. The price quoted shall include assembly, delivery, installation, debugging and training provided to the operators of the equipment. The equipment manuals for all of the sub-components are also to be provided upon delivery. The current system hardware for the 2.5 in. diameter manipulator (sting) shaft. The rotation axis is belt driven from the reduction gear box to the 2.5 in. diameter sting shaft, by the following components: Rotational Servo-Drive Motor: Motor: Yaskawa Electric AC Servo Motor Type: USASEM-15A-C2K S/N: 111828-1 KW KG-CM RPM A RATING 1.54 50 3000 10.4 Cont. Rotational Servo-Amplifier Yaskawa Electric CACR-SRCA -15BBB REV.E (O) DF8101720-E0 Reduction Gear Indiana Power Transmission Sys. Inc. Model: HQD-B-56C Ratio: 17.445: 1 S/N: 123091-2 HP 2.75 The translation axis is belt driven from the servomotor to the lead screw, by the following components: Translation Drive Motor: Motor: Yaskawa Electric AC Servo Motor Type: USASEM-03A-E2K S/N: R05HA123 W KG-CM RPM 308 10 3000 Translation Amplifier Yaskawa Electric CACR-SRCA-03BBB REV.D (1) DF8101720-D1 Reduction Gear None System PLC Unit MITSUBISHI "MELSEC-A" PLC RACK SYSTEM CARD LAYOUT: AINCPU, AD72, AY80, AX71, AY23 System uses a "BEIJER ELECRONICS" display unit: Model: E-300 Type: 02750C 24 VDC The system also contains three readout devices, which are "Red Lion" displays, which are fed from a PLC output card. The new display should replace the old "Red Lion" displays. The I/O configuration should be the same as identified in the existing Mitsubishi PLC card configuration layout listed above. Existing hardware items: The system has three rotational bearings; two are used to mount the translation table to the sting shaft and allow for rotation motion only. The third is a Thomson TM linear ball bearing, model number CMB-40 19207 SOCN, which is mounted inside a feed-through chamber with multiple wiper, quad and o-ring seals to maintain vacuum integrity. The translation drive system is a table arrangement that supports the rotational drive components, and uses two rotational Timken TM 2.5 in. bearings clamps (P/N 925ODE), and a Sealmaster TM bearing model RPB 208-2 around the sting shaft which are secured at both ends of the table. The table is attached to a ball screw arrangement that is mounted to a 1 in. diameter, 4 threads per inch pitch, lead screw.
