Chapter 6: System Operation enFORCE SAN Unit Operation Manual ¾ Data Number 61 - Load Hold Time The press will hold the [13: Target Load] or [22: Target Distance] for the amount of time set. If 999.9 (1 figure below the decimal) or 9999 (no decimal point) is set, Load Hold Time is set to no limitation. It finishes operating when the START signal goes OFF. If using the “Advanced” signal, a time must be set. The “Advanced” signal will stay on for this set time.
Chapter 6: System Operation enFORCE SAN Unit Operation Manual Distance Offset Setup Example This example describes how the system should be set up when using a 250mm stroke press and pressing to a Target Distance of 200.00mm (2 decimal place accuracy). 1.
Chapter 6: System Operation enFORCE SAN Unit Operation Manual Step Press Operation using the Time Controlled Press Method A Step Press is a press operation that is done in multiple phases using multiple parameters. This operation works best when used in conjunction with the “Keep Load” Return Operation. For best results set up as follows: For a smooth curve, set [18: Time Start Load] equal to the previous step’s [13: Target Load]. Turn On the Self Check Off signal before starting each cycle.
Chapter 6: System Operation enFORCE SAN Unit Operation Manual 6.5 Setting Up a Parameter for Returning It is recommended that, if the return of the press is done with a parameter, use Distance Control. However, if Target Distance is set to 0 without a return operation, the press will reject because the Distance Low value is zero (a value less than zero is not possible). Refer to the following for setting up a Return Parameter. Adjustments can be made according to the individual application.
Chapter 6: System Operation enFORCE SAN Unit Operation Manual 6.5 External LVDT Sensor In applications which require the use of an external sensor to measure when actual part contact is made and THEN determine what the final press distance would be, the use of an external LVDT is required. The enFORCE System allows external distance data to be input from an LVDT controller via an RS232 connection.
