STRAIGHT ELECTRIC SCREWDRIVER WITH TORQUE/ANGLE CONTROL BY BUILT-IN TRANSDUCER
Brushless electric screwdriver designed and built entirely by Fiam in Italy. It is an efficient, easy-to-use, green electric tool with a high level of performance and reliability, versatile and intelligent ideal for smart production organization in every industrial sector.
These screwdrivers are equipped with a built-in electronic torque transducer. Designed and manufactured by Fiam, it ensures high resolution in measuring torque parameters. The angle, on the other hand, is detected through integrated Hall sensors.
TORQUE ACCURACY of the screwdriver: ±5% with Cm and CmK ≥ 1.67
The screwdriver is paired with the TPU-A3 control unit, which offers numerous essential features to manage the tightening process quickly and correctly, making it both reliable and versatile.
This torque/angle control technology allows programming the tool to perform different assemblies with varying torque, speed, and many other parameters, making it suitable for multiple applications.
Front predisposition for mounting the screw suction head and use in efficient and fast Pick & Place operations (head to ordered separately). All eTensil tools synchronize perfectly with SSU vacuum pumps within the line control logic.

FUNCTIONALITY OF THE SYSTEM: SCREWDRIVER + TPU-A3 CONTROL UNIT
- 8 programs to control the tightening process
- 1 programmable sequence up to a max of 8 steps
- Retention Function: settable waiting interval between programs
- Automatic tool recognition and immediate configuration
- DISPLAY: status OK/NOK and, at the end of each cycle
- torque value in Nm
- angle value
- tightening time
- Displays the sequence of screws tightened with bright LEDs
- SCREW COUNTING (Poka Yoke device)
- TOOL SPEED can be set within the minimum/maximum range
-
Front lighting LED: adjustable intensity
-
UNTIGHTENING: can be activated/deactivated, settable speed
-
SOFT START: settable acceleration time
- Detect process anomalies like overtreading and already tightened screws through the control of the tightening time
- Store up to 99 tightenings (process statistics)
- They relate to the PLC or other devices and can be managed remotely
- Parameterizable functions to manage several applications
- 8 + 8 programmable I/O (21 + 22 signal types)
- Program Source function: when external devices — such as automatic accessory selectors — are connected, it is possible to manage the program‑selection mode.
- Smart Pro programming for end-of-cycle/anomalies/errors management
- Min / Max tightening angle control – Poka Yoke system
- SMART THREAD function: to process self-threading, self-tapping, self-drilling screws, or else where the final torque value is lower than thread forming torque
- SMART SPEED function: two-phase strategies with different speed: the first with a high speed tool rotation until reaching the set angle, the second with a pre-defined speed that allows to maintain the accuracy of the result. This function optimizes the tool’s behavior in applications with very hard joints, where it is necessary to precisely manage the progressive reduction of the initial speed in order to reach the final torque in a controlled mode. Thanks to the integrated torque transducer and the parametrization of the threading angle, it is possible to:
- control the approach to the target torque with greater accuracy
- reduce speed progressively and repeatably improving process control and tightening reliability.
• PRE-AUTO UNTIGHTENING: to set the untightening angle and the pause between the untightening and the subsequent tightening (application in the electrical / electronic field, for example when it is necessary to open and then close connectors to insert electrical wires)
• POST-AUTO UNTIGHTENING: the untightening angle is settable as well as the time pause of left rotation start after the tightening end• STOP-BY-TIME TIGHTENING: to tighten in depth and not to define torque• SMART TORQUE PROGRAMMING: allows setting a torque limit value beyond which the system automatically stops the tightening cycle. This function is useful to prevent abnormal and unsafe conditions for the operator, such as hand‑arm system kickbacks caused by high torque generated by damaged threads or non‑conforming components. It enhances process safety and reliability by enabling the immediate identification of component non‑conformities (defective threads, irregular materials, etc.).• PREVAILING TORQUE: monitoring of the average torque detected over the entire threading angle, with configurable acceptance thresholds for minimum and maximum values.
At the end of the threading angle, the screwdriver considers as target torque the set torque plus the detected average torque, in order to compensate for any torque losses due to friction. Possibility to choose whether to display only the Peak Torque of the final phase or the Peak Torque of the final phase + the Average Torque detected during the threading phase.
Benefits: material quality control and rejection of parts with out-of-range values, for example, in tightening applications with self‑locking nuts, where it is necessary to overcome the high friction generated by the plastic insert to prevent possible loosening of the nut. The prevailing torque function therefore allows monitoring the quality of the self‑locking nuts used.• AVERAGE TORQUE MONITORING (ROLLING): “test” function to display and verify the average torque on the component, by setting an angle-based strategy with: Threading angle = maximum angle = minimum angle. By setting the MIN and MAX Prevailing Torque according to the limits required by the customer, it is possible to verify the integrity of the component within the defined acceptability range. Typical application: integrity check of bearings.

REDUCED-EFFORT START UP: the pressure required to activate lever start up is much lower than others available on the market, only 9 N! Reducing the effort the user needs to sustain over the course of the working day, will result in increase of production efficiency. The reversible button works also for multifunctional programming and it is equipped with signaling leds.
Thanks to ERGONOMIC GRIP can be used by both right- and left-handed operators, and has also been designed to suit female hands. Ideal for tightening points on horizontal surfaces and coated with materials chosen to ensure just the right level of softness to the touch, while insulating the operator’s hand. Moreover, to increase safety and reduce operator fatigue, has anti-slip collars to prevent hands from slipping onto the tightening point.
APPLICATIONS
Thanks to their advanced technology, they guarantee maximum accuracy and precision in tightening, making them indispensable in industrial sectors where process control is essential for the quality of the finished product.
Moreover, by eliminating post-process checks used in traditional systems, they help reduce production time and costs.
