CONTROL UNIT TPU-C1

TPU-C1 control unit represents a great innovation INDUSTRY 4.0 able to manage all tools functionalities. It works with eTensil electric brushless screwdrivers and nutrunner motors with torque/angle current control, where the torque is detected by measuring the current used by the motor of the connected tool while the angle is detected by specific Hall sensors always integrated in the tool.

• Allows in-process torque adjustments during work by modifying the relevant parameter on the operating panel
• It detects process anomalies, by CHECK TIGHTENING TIME for example stripped threads or screws already tightened
• It interfaces with external equipment, the PLC, or other devices on the production line, such as workpiece‑clamping jigs, accessory selectors, and screw‑vacuum systems for automatic pick‑and‑place operations
• It can be managed remotely
• Allow to communicate the phase and the system status and to remote control the tool

BASIC FUNCTIONS: here are some of them, essentials to monitoring a tightening process correctly and making it reliable.

• 1 program to control tightening process
• Automatic recognition of the connected tool and immediate setting
• Screws counting: effective Poka Yoke device
• Displays: OK/ NOK status, torque value in Nm or other unit of measurement, tightening time value
• Min/Max tightening time control – Poka Yoke System
• Settable untightening speed
• 2 level password: to protect the set parameters or totally block the system
• Unit calibration
• Available measurements units: Nm/Lb/In./Kgf.cm
• Serial communication (RS232)
• Language selection (IT, EN, DE, FR, ES, TR)
• Storing the outcome of the last 99 tightening
• Program Source function: when external devices – such as automatic accessory selectors – are connected, it is possible to manage the program‑selection mode

• «SMART THREAD” function: for processing of selfthreading, self-tapping, self-drilling screws, or else where the final torque value is lower than thread forming torque
• “SMART SPEED” function: useful for speeding up the production process. It is possible to create a “two-phase” tightening strategy: screwdrivers start with a high-speed rotation until reaching the set angle, then rotate at a pre-defined speed that allows to maintain the accuracy of the result
• “S.R.O. Smart Range Optimizer” function: automatically identifies the most suitable final speed range to ensure the best tightening performance based on the set torque. The unit analyzes the selected torque value and dynamically calculates the optimal speed, which varies depending on the connected screwdriver model.
  The operator can then select, within this range, the speed that best fits the application.
  This prevents over‑torque errors, improves tightening quality, and increases the reliability of the entire tightening cycle.
