They are comprised
of a 32-bit RISC processor. Both controllers adopt the same fastening process
control technology. An optical encoder inside each screwdriver monitors the
rotation of the driver motor from the initial rotation until the completion of
the fastening cycle. The torque coefficient or factors which influence the
torque, is calculated by the controllers software from the continuously
monitored electric current to the screwdriver motor and the time factor. The
electric current from the controller to the screwdriver motor is based on that
continuous analysis, controlled instant by instant. The screwdrivers torque
output is in proportion to the controllers electric current output to the
screwdrivers motor. The screwdrivers torque curve takes 0.1 seconds and is
calculated by a functional circuit until it reaches the target torque. Once the
target torque has been reached, it holds that torque for 0.2 seconds to
stabilize the torque output.
controller has one channel for setting the torque output as a standard (two
channel controller optional).
Suitable for control of driver unit in manual operation. It is also applicable
for robotics auto application of simple screw tightening.
installed on a robot can catch and loosen an already seated (fastened) screw,
and has a memory for 8 preset fastening torque settings and 8 preset angle
settings. Suitable for robotics auto
applications. It is also applicable for control of driver unit in manual
operation, utilizing memory facility and/or with remote control combined.
Facilities available in FED III are :
Reversing parameter setting and
Idle mode (low torque & slow
speed) to engage with already seated screw
Multi-sequence program mode
can be used for manual and automatic application

MULTIPLE FEEDBACK CONTROL
Technart’s state-of-the-art multiple feed back control technology makes best
use of 32 bits RISC processor for real-time monitoring and control of screw
tightening torque and process.
RELIABLE CONTROL OF
TIGHTENING TORQUE AND PROCESS
FEDIII (FEDIII-h) monitors and controls motor current, motor voltage and motor
rpm, to control screw tightening torque and process. It guarantees reliable
repeatability of torque applied to screws, regardless of joint characteristics
and frictional differences in actual applications.
FEDIII (FEDIII-h), when powered on, automatically recognizes the connected
driver and its individual mechanical characteristics. A particular matching of
a controller and a driver does not need to be maintained.
MEMORY FOR DRIVER
TORQUE FAMILY DATA
FEDIII (FEDIII-h) can contain three different data of driver torque family.
When, for instance, FEDIII (FEDIII-h) contains torque family data of
3600/8500/12K, any of 3600, 8500 or 12K family driver can be connected and
used with it right away, without any manipulation.
Set a tightening torque digitally, and all the rest are taken care by FEDIII (FEDIII-h)
automatically, for best control of screw tightening at the torque for most
FEDIII (FEDIII-h) protects herself from any damage caused by overheat due to
repeated high load operations in too short an interval.
Every part inside the system and every stages of screw tightening and
reversing process are under comprehensive monitoring.
Two interfaces are available in standard : a 24-pin photo-coupler interface
and a serial RS-232C modular jack, for control and monitoring of the system
from external PLC or PC.
FUNCTIONS AND PARAMETERS
Many of functions and parameters can be customized, to best suit your specific
applications, via RS-232C interface from Technart Customizer software running
on your PC.
FEDIII (FEDIII-h) carries memory area for 8 different settings for each of
screw tightening and reversing.
FEDIII (FEDIII-h) provides facility of reversing screw by specified angle.
HIGH SPEED TIGHTENING
Model FEDIII-h carries High Speed control board (standard specification for
export) and provides high speed screw tightening and reversing, effective for
