specified in Sections 9.4.1 and 9.4.2, an Abnormal output will be generated and the
fastening process will be interrupted.
wSelf-check Function
The AFC1200 System is designed to perform several self-checks. Each time the
system is powered on, it completes a Power On Self-Test (POST) to verify the
compatibility and connection of all equipment. Refer to Chapter 9 -Troubleshooting-
for details of all system self-checks.
wServo Amplifier (Servo Drive)
Reduced equipment size with improved drive circuit strength is the result of
incorporating Isolated Gate Bipolar Transistor (IGBT) technology into the system. Axis
Controller Units are available in several models, and the Servo Amplifier housed in
each Axis Unit determines the model type. The Servo Amplifier also dictates the
nutrunner (tool) models that can be supported by the Axis Unit. The AFC1100 and
AFC1200 Systems incorporate the same Servo Amplifier and nutrunner components.
wAbnormal Condition Display
The System will output an ABNORMAL signal when it detects there is a problem
(Zero Check out of limits, incorrect component connection, etc.) within the system
itself. Dependent upon the type of Abnormal, the output may display as a code on an
Axis Unit, and/or as text on the system monitor. If the [HLP] key on the keypad is
depressed during an Abnormal output, the monitor will display additional information
for use in correcting the Abnormal condition. Refer to Chapter 9 Troubleshooting for
more details.
wCurrent Monitoring
The Servo output current provided to the motor is monitored and controlled through
the setting of warning and current control limits. The system can generate output
signals when the current is out of the warning or current control limits, allowing the
system to operate with a redundancy feature for the torque transducer operation.
