2.4 Functions
• Pressing Function
The following press control methods can be selected for the enFORCE System.
1. Load Control
2. Distance Control
3. Specified Point Load Judgment
4. Load
Rise Detection
5. Specified Range Peak Load Judgment
6. Time Controlled Press
7. Load
Drop Detection
8. Load Drop Detection (Point Stop)
9. Distance Control with Load Limit
Load and Distance can be monitored in any configuration.
• Early Interference Detection
If the parameters are set up for “Interference Check Distance” and “Interference Check Load”,
interferences early in the press cycle can be detected.
Interference Checking is performed during the high speed portion of the press stroke and is
useful for detecting: tooling left in the press path, misfed parts caught in receivers, etc.
• Part Checking – Work level part checks
If the parameters are set up for “Part Check 1 Load”, “Part Check 1 Distance Low” and “Part
Check 1 Distance High”, part checking will be performed.
“Low” Part Checking is useful in detecting: attempting to press completed parts, parts larger
than spec., holes smaller than spec., misaligned parts, etc.
“High” Part Checking is useful in detecting: missing parts, parts smaller than spec., holes larger
than spec., etc.
• Self-Check Function
If the SELF-CHECK OFF signal is HIGH (inactive or unconnected), the home-position (zero)
voltage level and CAL (full scale) voltage level of the load cell are automatically checked before
the cycle starts.
If the automatic system self-check of the load cell is not required, this function can be disabled
by forcing the SELF-CHECK OFF signal LOW before the cycle starts.
When operating with the signal HIGH, the equipment will correct the zero load level so the
equipment can adjust to external load changes, such as vacuum or gravity. The equipment will
use the previous zero load level if the equipment was started with the signal LOW (Active).
• Press Bypass Function (BYPASS)
When the Bypass input signal is activated through a PLC or when the RUN/BYPASS switch on
the front panel is switched to the Bypass position, the Bypass output signal is activated.
In this condition, the controller will not START.
If the unit is put into bypass mode when in cycle, it will stop functioning.
• Reject (NG) / Abnormal Condition Display
If a press reject or a system abnormal occurs, the tool will stop and output the appropriate
signal. It will also display the resultant reject data or abnormal number on the front panel.
When a press reject occurs, the tool will return if programmed.
• Tool Type Check Function
The contents of the ID is read in the following conditions
ƒ When a tool is already connected at the time of powering on.
ƒ When the tool is connected and preset data is downloaded from a users console to the
SAN unit.
The tools have an EEPROM in the preamplifier that contains tool data specific for each tool.
The tool type check function reads the information of the tool EEPROM and compares it to the
information contained in the SAN unit; any mismatch is reported as a Tool Type Error Abnormal.
