1.1 Functions Outline
w General
The AFC1200 ISA Fastening System is a culmination of over twenty (20) years of
electric fastening expertise integrated with the latest electronics technology. The basic
elements of this system are:
P Brushless DC permanent-magnet motor
P Combined Axis Controller/Servo Amplifier
P IBM-compatible 486 DX4 Central Processing Unit (CPU)
w Compact Design
As the result of miniaturization technology, the compact Axis Controller Unit maintains
a width of 100 mm in spite of the built-in power source and Servo Amplifier. The back
panel method of mounting provides easy access through the front of the enclosure to
all System connections, controls and indicators.
w Program Capabilities
The System software allows the use of all FEC fastening strategies and techniques,
which can be tailored by the end user to adapt to a variety of fastening applications.
Some of these features include:
torque control torque rate monitoring
angle control help mode
adaptive yield control sequence presetting mode
Speed Control
w Operational Interface
The ISA Main Controller Unit incorporates the user interface as an integral part of the
total System configuration. Pulldown menus display on the system monitor for
user-friendly nutrunner sequence programming. Eight different groups of preset data
may also be entered using the keypad provided as a system component. Preset data
and nutrunner sequences are preserved in non-volatile EEPROM.
w Communication Interface
External communication is available through the following means:
Standard Discrete I/O Centronics Parallel Port
Output RS232C Port RS422 Port (Option)
Input RS232C Port
w Motor
A DC permanent-magnet motor provides improved fastening control. The sealed
design of the motor provides greater protection from contamination without
generating any excessive heat.
w Preamplifier
Quality control of the tool torque transducer is accomplished electrically (digitally)
through the EEPROM in the preamplifier. During factory setup of the torque
transducer, the unit is dead-weight and dynamically tested against standards that are
certified and traceable to the National Institute of Standards and Technology. The
resultant data is then programmed into the preamplifier. The AFC1200 System
compares the programmed data with the actual measured data from the transducer,
and then compensates for minor discrepancies. If the variance exceeds the limits
