STRAIGHT ELECTRIC SCREWDRIVER WITH TORQUE/ANGLE CONTROL BY BUILT-IN TRANSDUCER

Brushless electric screwdriver designed and built entirely by Fiam in Italy. Efficient, easy to use and reliable tool for industrial assembly lines. Integrated torque transducer and Hall sensors provide high-resolution torque and angle measurement suitable for controlled production processes.

Torque accuracy
±5% with Cm and CmK ≥ 1.67.

Screwdriver + TPU-A3 control unit (system functionality)

• 8 programs to control the tightening process
• 1 programmable sequence up to 8 steps
• Automatic tool recognition and immediate configuration

DISPLAY: status OK/NOK

• torque value in Nm
• angle value
• tightening time
• Displays screw sequence with LEDs
• SCREW COUNTING (Poka Yoke)
• Tool speed adjustable within range
• Adjustable front lighting LED
• Untightening: activatable/deactivatable, programmable speed
• Soft start: adjustable acceleration time
• Detects process anomalies (overtreading, already tightened screws) via tightening time control
• Stores up to 99 tightenings (process statistics)
• Interfaces with PLC and can be managed remotely
• SMART THREAD for self-threading/self-tapping/self-drilling screws
• SMART SPEED: two-phase speed strategy for accuracy
• Parameterizable functions for multiple applications
• 8 + 8 programmable I/O (21 + 22 signal types)
• Smart Pro programming for end-of-cycle/anomaly/error management
• Min/Max tightening angle control – Poka Yoke
• Displays ANGLE, TIGHTENING TIME and TORQUE at cycle end

Special functions

• PRE-AUTO UNTIGHTENING: set untightening angle and pause between untightening and subsequent tightening (useful for connector operations)
• POST-AUTO UNTIGHTENING: set untightening angle and pause before left rotation after tightening
• STOP-BY-TIME TIGHTENING: tighten by depth/time without defining torque

Prevailing torque and monitoring

• PREVAILING TORQUE: monitors average torque over the threading angle with configurable acceptance thresholds; target torque compensated by detected average torque to offset friction losses
• AVERAGE TORQUE MONITORING (ROLLING): test function to display and verify average torque using an angle-based strategy

Tightening strategies

• Torque control
• Torque control with angle monitoring
• Torque control with time monitoring
• Torque control with time and angle monitoring
• Angle control with torque monitoring
• Time-based control with torque monitoring (Stop-by-time)
• Prevailing torque control
• Average torque monitoring (rolling)

Features

• Start: lever
• Front preparation for screw suction head mounting
• Front LED light
• Connection cable supplied (3 m)
• Quick change chuck (female hex 1/4")
• ESD certified
• Performance certificate for torque values (valid 1 year)
• Extended warranty: 2 years or 1,000,000 cycles

Ergonomics and use
Low activation effort: lever pressure only 9 N. Reversible button for multifunction programming with signalling LEDs. Ergonomic straight grip suitable for right- and left-handed operators, designed for smaller hands with soft coating and anti-slip collars.

Applications
Industrial-grade tightening where process control and traceability are required, reducing post-process inspections and production costs.
