Electric nutrunner eTensil E8CC 90

right-angleinstrumentedwith torque control

Brushless electric angle nutrunner with 90° offset head and torque/angle current control.
Designed and manufactured by Fiam in Italy for Industry 4.0 production environments: compact for confined spaces, low maintenance and high tightening accuracy.

Torque is detected by measuring motor current; angle is measured via integrated Hall sensors.
Torque and angle parameters can be adjusted during the assembly cycle from the combined control unit (TPU-C1 or advanced TPU-C3).

• Lever start requires only 9 N.
• Reversible button supports multifunction programming and includes signaling LEDs.
• Ergonomic ambidextrous grip designed for reduced operator effort and to suit female hands.

Basic functionality of the system: screwdriver + TPU-C1 control unit

• 1 program to control the tightening process
• Automatic tool recognition and immediate configuration
• OK / NOK result display and tightening time
• Sequence display of tightened screws with LEDs
• Screw counting (Poka Yoke)
• Tool speed adjustable within min/max range
• Adjustable lighting LED intensity
• Untightening: activatable/deactivatable, settable speed
• Soft start: adjustable acceleration time
• Detect process anomalies via tightening time monitoring
• Store up to 99 tightenings (process statistics)
• Remote management and PLC interfacing
• Smart Thread for self-threading/self-tapping/self-drilling screws
• Smart Speed: two-phase strategies for speed/accuracy
• Parameterizable functions for multiple applications
• 8 + 8 programmable I/O (9 + 11 signal types)
• Smart Pro programming for end-of-cycle/anomaly/error handling
• Industry 4.0 connectivity with factory management systems

Tightening strategies (TPU-C1)

• Torque control
• Torque control with tightening time monitoring

Additional functions of the system: screwdriver + TPU-C3 control unit
TPU-C3 includes all TPU-C1 functions plus additional options:

• Min / Max tightening angle control — Poka Yoke system
• Displays ANGLE value at end of cycle together with tightening time and torque
• 8 programs to control the tightening process
• 1 programmable sequence up to 8 steps
• 8 + 8 programmable I/O (21 + 22 signal types)
• Pre-auto untightening: set untightening angle and pause between untightening and next tightening (useful for connectors)
• Post-auto untightening: set untightening angle and left-rotation pause after tightening
• Stop-by-time tightening: tighten by depth/time without defining torque

Additional tightening strategies (TPU-C3)

• Torque control with tightening angle monitoring
• Torque control with time and angle monitoring
• Angle control with torque monitoring
• Time control with torque monitoring (stop-by-time tightening)

Features

• Front lighting LED
• Connecting cable supplied (3 m)
• Quick change chuck (1/4" male square drive)
• ESD certified
• Extended warranty: 2 years or 1,000,000 cycles

Applications
Industrial production lines requiring high flexibility: ideal for automotive and household appliance sectors and for tightening in tight or hard-to-reach spaces (against walls, near frames, profiles and shaped parts).

Also available models with Female hex. output coupling for inserting tools (BITS models).
