Industrial Servo-Control Development Specialist Needed

Delta PLC, Servo Motion, HMI and SCADA Programmer Required Project Overview We are developing two industrial servo-controlled products: 1. Servo Nutrunner 2. Servo Pressing Spindle We require an experienced PLC, servo-motion, HMI and SCADA programmer to develop the control software, operator interface, graphical process monitoring, data logging, reporting and machine diagnostics. This is not only an HMI-development assignment. The programmer must have practical experience in servo motion control, torque-angle monitoring, force-displacement monitoring, PLC programming, industrial communication, database integration and machine commissioning. Proposed Hardware Servo Nutrunner * Controller: Delta PLC * Servo drive and motor: Delta ASDA-B3 * Torque feedback: Servo-drive torque feedback and/or external torque transducer * Angle feedback: Servo motor encoder * HMI/GUI: Delta HMI, VB.NET, C#, Lua or suitable industrial SCADA * Communication: EtherCAT, CANopen, Modbus TCP/RTU or another suitable protocol Servo Press * Controller: Delta PLC * Servo drive and motor: Fuji Electric ALPHA7 * Force measurement: Load cell with amplifier * Displacement measurement: Servo encoder, rotary encoder or linear encoder * HMI/GUI: Industrial HMI or Windows-based application * Database: SQL Server Express or another approved database Scope 1: Servo Nutrunner The operator shall be able to create and save tightening recipes containing: * Target torque * Target angle/theta * Minimum and maximum torque * Minimum and maximum angle * Rundown speed * Final tightening speed * Acceleration and deceleration * Snug/seating torque * Torque hold time * Cycle timeout * Reverse speed and angle * Part number, recipe and batch quantity The tightening sequence may include: 1. High-speed rundown 2. Snug-point detection 3. Low-speed tightening 4. Torque-controlled tightening 5. Torque-plus-angle tightening 6. Hold or verification 7. Controlled stop and reverse 8.

The system should also support multiple checking windows at selected force or displacement ranges. HMI and GUI Requirements The HMI/GUI should include: * User login * Automatic cycle * Manual/setup mode * Recipe creation and selection * Live torque-angle graph * Live force-displacement graph * Previous-cycle graph * Large OK/NOK indication * Batch and production counters * Alarm screen and alarm history * Servo diagnostics * PLC I/O diagnostics * Calibration screen * Maintenance screen * User management * Data search and report screen SCADA and Traceability Every cycle must be stored with: * Date and time * Shift * Operator name/ID * Machine number * Product and part number * Serial number * Batch number * Recipe name and revision * Target values * Actual measured values * OK/NOK status * Failure reason * Cycle time * Torque-angle or force-displacement curve Users must be able to search records by date, shift, operator, part number, serial number, batch, recipe and OK/NOK status. Reports required: * Individual cycle report * Batch report * Shift and daily production report * Operator-wise report * Part-wise report * OK/NOK and rejection summary * Alarm-history report Reports should be printable and exportable to PDF, Excel or CSV. Database backup and restoration must be provided. User Access and Security Access levels should include: * Operator * Setter * Supervisor * Maintenance * Quality * Administrator Recipe editing, calibration, limit changes and user creation must be password protected. The system should maintain an audit trail of logins, recipe changes, calibration changes, alarm acknowledgements and manual overrides. Calibration and Diagnostics Calibration facilities are required for: * Torque * Load cell * Angle * Displacement * Zero and span * Calibration factor * Calibration date and due-date warning Alarms should cover: * Servo not ready or servo fault * Encoder fault * Torque/load-cell fault * Overtravel * Home-position fault * Emergency stop * Safety-door open * Excess torque or force * Cycle timeout * PLC/servo/database communication failure * Printer failure * Workpiece not present Deliverables The programmer must provide: 1.
