The MY-TR from Anlidar Industrial (branded as MyTorq) is an economy torque monitoring and control unit designed as the electronic companion to MyTorq's TR-series electric screwdrivers (MY2-TR through MYT-TR). It serves three functions simultaneously: it provides adjustable DC power to the screwdriver motor with programmable slow-start ramping; it monitors the tightening process in real time by analyzing motor current as a proxy for output torque, detecting OK/NG conditions against user-set torque and time windows; and it collects and transmits assembly data — torque value, rundown time, and pass/fail status — through dual RS-232 serial ports for quality traceability systems.

How does the MY-TR prevent assembly errors without a full transducerized torque tool?

Rather than relying on an expensive in-line torque transducer and angle encoder, the MY-TR uses motor current monitoring correlated to output torque — an indirect measurement technique that is less accurate than direct torque sensing but sufficient for error-proofing applications where the primary requirement is detecting gross errors: cross-threaded fasteners, missed screws, stripped threads, or incorrect screw length. The controller compares the peak current during each tightening cycle against a user-programmed torque window (0.0–550.00 kgf·cm) and stop time window (0.00–9.99 seconds). A fastening that exceeds the torque window triggers an NG output; a fastening completed within both time and torque windows triggers an OK output. These discrete signals connect directly to PLC inputs, stack lights, or line-stop relays for immediate error response without requiring a connected PC. For applications demanding high-accuracy torque measurement, MyTorq's higher-tier Sirius series adds a dedicated torque transducer and angle encoder with <1% tolerance.

What does the 99-program sequencing capability enable for mixed-model assembly lines?

The MY-TR can store 99 distinct tightening programs, each with its own torque window, slow-start ramp, speed setting, and batch count. Up to 8 programs can be chained in a single sequence — for example, an engine assembly station tightening 8 different fasteners to 8 different torque specifications in a defined order. The controller advances through the sequence automatically as each batch count is satisfied, and a sequence-cleared external input allows the PLC or operator to reset the sequence for the next workpiece. This program-chaining capability enables a single MY-TR to manage complex multi-fastener assembly stations without an external PLC orchestrating program changes — the controller handles the sequencing internally based on batch completion signals. Barcode reader integration adds traceability: scanning a workpiece serial number links the assembly data record to that specific unit for downstream quality audit and warranty claim investigation.
