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
PEDIII (PEDIII-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 joint
characteristics and frictional differences in actual applications.
PEDIII (PEDIII-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 PEDIII (PEDIII-h) can contain three different data of driver torque
family. When, for instance, PEDIII (PEDIII-h) contains torque family data
3600/8500/12K, any of 3600, 8500 or 12K family driver can be connected and
used with it right away, without any manipulation.
SETTING Set a tightening torque digitally, and all the rest are taken care
by PEDIII (PEDIII-h) automatically, for best control of screw tightening at
the torque for most applications.
OVERHEAT PROTECTION PEDIII (PEDIII-h) protects herself from any damage caused by
overheat due to repeated high load operations in too short an interval.
MESSAGES Every part inside the system and every stages of screw tightening
process are under comprehensive monitoring.
INTERFACES Two interfaces are available in standard : a 24-pin photo-coupler
interface and a serial RS-232C modular jack, for control and monitoring 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.
HIGH SPEED TIGHTENING
CONTROL Model PEDIII-h carries High Speed control board (standard
specification for export) and provides high speed screw tightening, effective
for most applications.
