1.2 Outline of Functions
{ The AFC1100 Fastening System is a culmination of over twenty years of electric fastening
expertise integrated with the latest electronic technology. The basic elements of this system
are:
1) A brushless DC permanent magnet motor
2) A combination Controller/Servo Amplifier
{ 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. System
components are mounted on the back panel inside of the NEMA 12 enclosure. All
System connections, controls, and indicators are easily accessed through the door on
the front of the enclosure.
{ Fastening Function
The following fastening control methods can be selected for either Clockwise (CW) or Counter
Clockwise (CCW) opreation:
P Torque control - Angle monitoring - Torque rate monitoring - 1 fastening step.
P Torque control - Angle monitoring - Torque rate monitoring - 2 fastening steps.
P Angle control - Torque monitoring - Torque rate monitoring - 1 fastening step.
P Angle control - Torque monitoring - Torque rate monitoring - 2 fastening steps.
P
The Two fastening steps method can be used by multiple Axis unit systems where the
SYNC signal can control the simultaneous operation of all spindles. Thus, the spindles
start and stop when they have reached the predefined value. They will start again
simultaneously to reach the final torque.
{ Optional Interface
The User Console incorporates the user interface as an integral part of the total System
configuration. On-screen, user-friendly nutrunner programming and data collection can
be performed via the optional user console. Eight different groups of preset data may
be entered using the user console and than downloaded to multiple Axis units where it is
preserved on an EEPROM indefinitely.
{ Communication Interface
External communication is available through the following means:
Standard Discrete I/O User Console Centronics Parallel Port (Optional)
RS422 Port Printer InterFace unit (Optional)
{ Motor
A DC permanent magnet motor provides for improved fastening control. The sealed
design of the motor provides greater protection from contamination without generating
any excess heat.
