STRAIGHT ELECTRIC SCREWDRIVER WITH TORQUE/ANGLE CURRENT CONTROL

Designed and manufactured by Fiam in Italy, is a handheld brushless electric screwdriver for industrial assembly lines. Torque is deduced from motor current measurement while angle is measured by integrated Hall sensors. Torque and angle parameters can be adjusted during assembly through the connected power/control unit (TPU-C1 or TPU-C3).

Ergonomics & safety
The lever start requires only 9 N activation force to reduce operator fatigue. The reversible button also serves as a multifunction programming key with signaling LEDs. The ambidextrous ergonomic grip is designed for smaller hands, coated with soft insulating material and positioned for easy centering at the fastening point.

Pick & Place readiness
Front predisposition for mounting a screw suction head (ordered separately). Compatible with SSU vacuum pump for Pick & Place integration.

Basic system functions (screwdriver + TPU-C1)

• 1 program for tightening process control
• Automatic tool recognition and configuration
• OK/NOK display, torque value in Nm and tightening time
• Sequence and screw count display via LEDs (Poka Yoke)
• Adjustable rotation speed within min/max range
• Clockwise/anticlockwise tightening; untightening can be enabled/disabled
• Programmable soft start (acceleration ramp)
• Cycle-time monitoring for anomaly detection (cross-threading, pre-tightened screws)
• Memory of up to 99 tightenings
• Remote tool control and PLC / workstation interfacing
• 8 + 8 freely programmable I/O

Advanced functions (examples)

• SMART THREAD: for self-threading/self-tapping/self-drilling screws where final torque is lower than thread-forming torque
• SMART SPEED: two-phase strategy — high speed until set angle, then controlled speed for precision
• S.R.O. – Smart Range Optimizer: automatic identification of optimal final speed range based on selected torque

Tightening strategies

• Torque control
• Torque control with cycle-time monitoring

Additional system functions (screwdriver + TPU-C3)
Includes all TPU-C1 features plus:

• 8 programs to control the tightening process
• 1 programmable sequence up to 8 steps
• Display of detected angle, OK/NOK status, torque and tightening time
• Min/Max tightening time and Min/Max tightening angle control (Poka Yoke)
• 8 + 8 freely programmable I/O (expanded signal types)
• Retention: programmable wait interval between programs

Cycle-related functions

• PRE-AUTO-UNTIGHTEN and POST-AUTO-UNTIGHTEN with configurable angle and pause time
• TIME-BASED TIGHTENING for depth-controlled applications

Features

• 4 start modes selectable from power unit: lever, push, lever+push, latched lever+push
• Front predisposition for screw suction head
• Work area LED illumination
• Connection cable supplied
