Data Storage
Each SAN3 unit stores approximately the last 12,300 fastening results in memory as well as
the last 256 Abnormal conditions. (SAN2 units DO NOT support data storage). Data is erased as a
result of FIFO (First In First Out) or via the AFC user console. Date stamping of data does not take
place in the Stand alone SAN units unless new SAN-DP1 display is connected (DP1 which supports
the clock function) or when stored data is collected via a Multi Unit configured system. The data list
that is stored in a Stand-alone SAN3 –xxx unit is as
follows;
1. Cycle Count 9. Final Torque
2. Date (only with new SAN-DP1 display connected) 10. Final Angle
3. Time (only with new SAN-DP1 display connected) 11. Cycle Time
4. Fastening Method
12. 1 st Rate
5. Fastening Steps 13. 2 nd Rate
6. Judgment 14. 3 rd Rate
7. Parameter Number 15. Snug Torque
8. Peak Torque

Preamplifier
Quality control of the tool torque transducer is accomplished electronically (digitally) through
the EEPROM (Electrically Erasable Programmable Read Only Memory) in the preamplifier. During
factory setup of the torque transducer, the unit is Dead Weight and dynamically tested against Stan-
dards that are certified and traceable to the National Institute of Standards and Technology. The re-
sultant data is then programmed into the preamplifier where it is stored on non volatile EEPROM.
• Servo Amplifier (Servo Drive)
Reduced equipment size with improved drive circuit strength is the result of incorporating In-
sulated Gate Bipolar Transistor (IGBT) technology into the drive System. SAN units are available in
several models. The Servo Amplifier housed in each SAN unit determines the model type. The Ser-
vo Amplifier also dictates the nutrunner (tool) models that can be supported by the SAN unit.
• Plug-In Firmware Update System
The SAN Firmware is stored in Flash ROM and can be rewritten with future Firmware up-
dates via a plug-in connector located on each unit. There is no need to remove the unit or disassem-
ble the unit for any Firmware upgrades.
• Motor and Resolver Combined Cable
A combined motor and resolver cable reduces the number of cables in the system. The torque
signal cable is separate for better torque signal management.
•
Multi Unit Connectivity
A main controller or Multi Unit can be connected to a single spindle or group of up to 31 spin-
dles to control all spindle(s) from a single point of I/O. The Multi Unit assumes all fastening sequenc-
ing, fastening data monitoring / analysis and all data communication. Without the use of the Multi
Unit, individual spindle sequencing is limited to basic multi step operations.
•
Network Connectivity
Connection to an Ethernet network can be accomplished via the addition of the Multi Unit. For
specific capabilities related to Ethernet protocols, please contact FEC Inc.
