ELECTRIC NUTRUNNER MOTOR WITH TORQUE/ANGLE CONTROL BY BUILT-IN TRANSDUCER AND ENCODER
Brushless electric nutrunner motor designed and built entirely by Fiam in Italy for automatic use on machines and for the needs of Industry 4.0 With modular construction for safe maintenance management. Built-in electronics.
To be combined with E‑TCS control unit, it ensures::
- High flexibility in managing assembly processes
- Full traceability of all completed assemblies (Industry 4.0)
- High tightening accuracy
- Multiple control and/or monitoring modes for TORQUE/ANGLE/TIME tightening
- Cost reduction thanks to decreased scrap rates
- Easy integration into production lines
- Each individual tightening system (nutrunner motor and control unit) can be programmed to perform different assemblies with different torque, speed, and other parameters, allowing it to be used for several applications
Specifically for use in industrial automation, because it is equipped with:
- strong thrust bearings: they withstand the thrust of the sort of slides found in automated production cycles that move in rapid, non-stop strokes
- ideal external geometries: they make machine mounting practical along the full length of the aluminium outer body
- centring system: designed to achieve unbeatable reliability along both the vertical and horizontal axis.
- guaranteed long-term gear efficiency: careful design, dimensioning and innovative processes ensure that the performance of the reduction unit is almost unchanged even after hundreds and hundreds of operating hours as certified by our laboratories
FEATURES
- Integrated torque transducer and encoder: ensure high resolution in the measurement of torque/angle parameters.
- Status LED to directly check the result of the tightening cycle on the motor.
- Compact design, reduced dimensions and above all low weight make them ideal for installation on single or multiple tightening units and on robots.
- ESD certified
- This model is supplied without axial compensator.
- Mounting flange included.
- Connection cable to be ordered separately: various lengths available, also with 90° connector.
- Available models with: off‑set device for close tightening center distances, axial compensator (to be ordered separately), modified flange and/or customized body design, angled head.
FEATURES OF E-TCS CONTROL UNIT
Powers and controls all functions of the connected E MCB electric tightening tool, enabling advanced programming and accurate control of every phase of the tightening process, with real-time visualization on the color Touch Screen panel.
-
VISUALIZATIONS
- Complete visualization of the tightening process
- Instant display of TORQUE/ANGLE/TIME of tightening
- Graphical visualization of tightening data
- Tightening result indication through display color changes and tool‑mounted light signals
- Last 200 tightening log records
- Last 200 tightening diagrams
-
PROGRAMMING
- Poka‑yoke programming directly on the color touch screen
- 100 configurable Jobs, recallable from operator
- 100 configurable Tasks for each Job
- 12 configurable Steps for each Task
- WIZARD programming of tightening strategies: guided, from Job level down to Step level
- Programming screens available in two languages (English EN, Italian IT)
- I/O test screens: it is possible to force the state of inputs and outputs directly from the unit; useful during diagnostics/commissioning when no PLC is used
-
3 TIGHTENING STRATEGIES
- Settable within the Steps:
- Torque Control – Angle Monitoring (TC‑AM)
- Angle Control – Torque Monitoring (AC‑TM)
- Torque and Angle Control (AC and TC)
- Settable within the Steps:
-
OTHER TYPES OF TIGHTENING CYCLE CONTROL
-
- Tightening with clockwise or counterclockwise rotation (for example: if counterclockwise rotation is selected, the system tightens and controls in that direction, performing loosening clockwise)
-
- Minimum/maximum tightening torque control
-
- Minimum/maximum tightening angle control
-
- Minimum/maximum tightening time control
-
- Threshold torque for angle reading and monitoring
-
- Screw counting
-
- For each screw: programming of the maximum number of re‑tightening attempts in case of NOK screw
-
- Configurable loosening speed and direction
-
- Speed reduction during tightening with configurable final torque/speed values (downshift)
-
- Acceleration ramp duration
-
-
DATA STORAGE AND EXPORT
-
- Tightening logs exportable via Fieldbus (e.g. PROFINET – MODBUS TCP – ETHERNET /IP)
-
- Import/export of tightening programs
-
- Data storable on SD‑card, and therefore exportable
-
- The system can handle a capacity of over 1 million tightenings
-
- Data storable on SD‑card, and therefore exportable
-
-
OTHER FEATURES

- Fieldbus port for connection to the most widely used fieldbus systems
- USB port for unit and tool firmware updates, for importing/exporting tightening program parameters, or exporting tightening logs
- SD port for SD‑CARD containing programs and tightening logs; removable for backup operations
- Multiple authorization levels protected by password, up to 4 users
- Power cable
- Integrated date and time clock
- 120V~230 Vac ±10% 50‑60 Hz
- Code: 686200210
- Code: 686200211 (model E‑TCS‑120V, with cable with American plug)

APPLICATIONS
- To tighten any threaded element, in single or multi-spindle assembly units to assemble multiple elements at the same time. They can be controlled automatically and inserted into automated assembly lines, in rotary table machines, on fastening slides, on electronic axes to assemble on different planes or on versatile and always reconvertible anthropomorphic robots.
- Industrial production environments where high quality and great production flexibility are required: the system adapts to the variability of production batches and therefore to the different types of screws to be used.
