Torque Drive

The systems table shows the torque range for the M-Series (hand operated). The RPM is automatically selected in accordance with the torque value you program in the controller.

Each model has the ability to switch to either standard or high speed using the customized software.

If you require any specific RPM for a certain fastening torque, please feel free to contact a customer service representative. We need to know your specific fastening torque in use, so we can determine if the RPM you require can be achieved.

A-Series Drivers
with automatic recognition

The A series driver is intended for application of remote control operation installed in robotics. It is designed to minimize particles, static charge and magnetic noise emission. It is suitable for cleanroom application. Vacuum suction for screw pick-up also collects particles emitted during screw fastening. Optional bit cushion mechanism minimizes shock to delicate work-piece.

Continuous Bit Grounding Mechanism (see ESD solution) is also available optionally for most ESD-sensitive environments.

Two types of bit mount are prepared in standard : 4 mm diameter. D-cut (half-moon) shank bit mount (for M1 to M3 small screws) and 6.35 mm (1/4 inch) HEX shank bit mount (for M4 to M5 screws). Both adopts one-touch quick change chucking mechanism.

The A-Series driver unit's power and direction are controlled by either the PED III or the FED III controller and are used for automatic applications. The FD and FH models are equipped with a bit cushion mechanism. The bit has a moveable range of 10mm in the axis direction and +/- 1 mm (from bit center) in the circumference direction (360°). The driver unit can keep the same bit pressure anywhere within the moveable range.

Model Number Configuration

The product line-up offers several choices to meet your requirements. The following will explain how to specify a model.

System (a controller + a driver unit) =

	Controller Models: PED III and FED III
	Model Series: M, S and A
	Driver Unit Models: 1200, 2200, 3600, 8500, 12K, 15K, 20K and 30K
	Configurations: SD, FD, SH, and FH

Example: PED III-M 8500-SH

Bit Sleeve & Guide
A bit sleeve is unique to the application. In order to complete the order for your system, we require:

• Sample of a fastener or dimensions of fastener
• Specific driver style being used
• Shank diameter
• Special requirements i.e. space restrictions

Custom Options and Settings

User-friendly Windows 95/98/NT^® based software is available to customize the functions and parameters of the PED III or FED III controller.

Custom Functions

• LED (for M and S drivers)
• Screw binding release
• Trigger switch and forward/reverse switch (for M and S drivers)
• Dual torque: Manual or Auto change-over (for PED III)
• Slow start for initial engagement to minimize shock and cross threading of fasteners.

User Parameter Settings

• Changeable unit measure (kgf.cm, N.m, Lbf.in)
• Driver unit LED functions
• Standard speed fastening setting
• High speed fastening setting
• Holding time of peak torque (0-200ms)
• Screw binding release function parameters
• Reversing parameters (FED III only)
• Idle mode parameters (FED III only)
• ATC (Auto Torque Compensation) fine-tuning to adjust the mechanical characteristics of the driver unit.

Multi-Sequence Operation

A programmable multi-sequence operation without a PLC (FED III) is available with the customized software.

1. RELIABLE REPEATABILITY OF TIGHTENING TORQUE
   The tightening torque set on the Technart controller is precisely conveyed to the driver unit, controlled and maintained, regardless of joint characteristics and frictional differences.
2. MINIMUM G-SHOCK
   Shock and impact to the work-piece is minimum, thanks to the unique driver mechanism and tightening process control.
3. SUITABLE FOR USE IN CLEAN ROOM ENVIRONMENTS
   It is designed to minimize particle emission, static charge and noise interference, making it suitable for use in Clean Room environments.
4. TORQUE FAMILY LINEUPS COVERING WIDE RANGE OF TORQUE
   A wide range of torque family models is available in standard, covering 0.03 to 2 Nm..
5. SIMPLE AND COMPACT DESIGN FOR EASY INSTALLATION
   Its simple and compact design makes it convenient and easy to install on robot etc..
6. SIMPLE MAINTENANCE
   Replacement of bit, sleeve etc. and also cleaning is simple and easy to access.
7. RELIABLE VACUUM PICKUP OF ANY SIZE / TYPE SCREW
   Vacuum pickup of screw is effective for any type, size or material of screw.
8. ONE-TOUCH QUICK CHANGE CHUCK FOR INTERNATIONAL INDUSTRY STANDARD BIT SHANK
   International industry standard shank bit can be fitted directly.
9. RELIABLE CONNECTOR AND FLEXIBLE CABLE
   For connection between controller and driver, flexible cable for robotic use fitted with self-lock connector is used.
10. ERROR DETECTION
    Alarm is output by controller when screw tightening has not been completed successfully.
11. OPTIONAL BIT CUSHION
    Optional bit cushion mechanism absorbs and minimises impact and shock to delicate work-piece.
12. OPTIONAL BIT GROUNDING MECHANISM
    A sister model AG is equipped with continuous bit grounding mechanism. It achieves complete grounding even during the bit rotation and is ideal for use in most critical ESD sensitive environments.
