TN301 Series is a torque driver system comprised of a versatile controller driven by 32-bit RISC processor and a powerful AC brushless servo motor driver. . The state-of-the-art multiple feedback control technology designed by Technart now meets high speed AC brushless servo motor carrying high resolution encoder. . Its precise and realtime control guarantees reliable, efficient and high speed control of screw tightening and torque, regardless of joint characteristics and frictional differences, for any type of screw and for any type of work. . The TN301 controller is designed for versatile control and monitoring of screw tightening and reversing operation, and can cope with any complicated process requirement. . Many of control parameters and functions can be customized by use of Customizer software (running on Windows 98/2000/XP®), to best suit any specific requirement or application, without any hardware modification.

Main Features

REALTIME FEEDBACK CONTROL

Technart's state-of-the-art multiple feedback control technology makes best use of 32-bit RISC processor for real-time monitoring and control of screw tightening torque and process at possible fastest response. 

DURABLE AC BRUSHLESS SERVO MOTOR

Technart's control combined with long-life and durable AC brushless servo motor realizes reliable screw tightening at very high speed to low.

RELIABLE CONTROL OF SCREW TIGHTENING PROCESS & TORQUE

TN301 controller monitors driver motor current, voltage and rpm. It controls screw tightening process and torque in real-time, for best repeatability of torque applied to the joint, regardless of joint characteristics and frictional differences in actual applications.

DRIVER IDENTIFICATION

TN301 controller, when powered on, automatically recognizes the connected driver model and its particular mechanical characteristics, for output torque adjustment (OTA). A matching of a controller and a driver unit doesn't need to be maintained anymore. The same setting always brings the same result.

EASY UPGRADE BY FLASH ROM

TN301 stores its control program in flash ROM. Most of future implementation of optional functions won’t require hardware modification.

SIMPLE DIGITAL TORQUE SETTING

Set a tightening torque digitally, and all the rest are taken care by TN301 for best repeatability control of screw tightening at the torque for most applications, by optimized control parameter set.

OVERHEAT PROTECTION

TN301 protects itself from any possible damage caused by overheat that may be caused by repeated high load operations in too short an interval.

COMPREHENSIVE ERROR MESSAGES

Every parts inside the system and every stages of screw tightening and reversing process are comprehensively monitored. The error message will help you to pinpoint the cause of the problem.

TWO STANDARD INTERFACES

Two interfaces are equipped in standard - a 24-pin photo-coupler interface and also a serial RS-232C modular jack, for control and monitoring of the system from external PLC or PC.

CUSTOMIZING OF PARAMETERS & FUNCTIONS

Many of parameters and functions can be customized, to best suit your specific application, via RS-232C interface, from Technart Customizer software running on your PC with Windows 98/2000/XP®.

PRESET MEMORY

TN301 offers facility of 8 preset memory area for each of screw tightening and reversing, to house different parameters. 

REVERSING ANGLE CONTROL

TN301 can control reversing by specified angle very precisely, thanks to the high resolution encoder on board the driver.

ULTRA HIGH SPEED SCREW TIGHTENING

TN301 realizes ultra high speed screw tightening, thanks to the AC servo motor of very low inertia. It can meet the fastest cycle time requirement. 

MULTI-SEQUENCE PROGRAM

TN301 provides a program mode, in which you can compose a program comprised of two or more steps.

FRONT PANEL KEY & SWITCH LOCK

Locking of front panel keys from Customizer can prevent unwanted accidental change of settings.

REAL-TIME MONITORING

Comprehensive process data are output via RS-232C, for real-time monitoring and recording of every single operation. Additionally, with Option Pack applied to TN301, Customizer can display Motor Current Curve and Realtime Monitoring Curve as well for visual monitoring and analysis.

SELF DIAGNOSIS

The self diagnosis command will help you to evaluate conditions of driver unit, by rotating it when it is free with no actual load on it and measuring the load of motor shaft.

BREAKAWAY TORQUE & FIRST MOVEMENT TORQUE MEASUREMENT

With Option Pack applied to TN301, a unique command will become available, to measure and evaluate breakaway torque and first movement torque.

MULTI-SPINDLE SYNCHRONIZING CONTROL

With SYNC option applied to TN301, it can become a part of a system controlled by MSTC (multi-spindle synchronized screw tightening & reversing controller), for synchronized screw tightening and reversing by two or more TN301 and drivers.

SP EDIT

The SP EDIT is an add-on facility which becomes available by applying Option Pack #3 to TN301. This is the most powerful customizing facility. You can customize control parameters for each stage of screw tightening process. The fine-tuning and optimizing of screw tightening process control to a specific application, by SP EDIT, will realize the possible fastest cycle time for the application. It is especially effective for tapping screw application, and also for screw tightening against very soft joint.
