Dynamic Hold Method

Dynamic
Hold Method Submenu Diagram
The hold process related to the servo press is split into two
parts. The dynamic hold is executed before the static hold.
The hold process can include one or both of these methods
and both may be disabled.
The dynamic hold method occurs after the weld method
has completed. The dynamic hold method continues the
movement of the horn until a user-specified distance occurs
or until a user-specified force is achieved. Holding allows
the material to solidify (under pressure) before the press
head retracts. Hold method choices are:
• Until Force Reached,
• Distance,
• Disabled
Until Force Reached -
This setting keeps a user-defined
speed on the part until the force of the press reaches the
specified peak force following the weld process. A user
specified maximum time prevents an infinite hold. This
option is only available when using speed motion control.
A user specified maximum time prevents infinite holding
due to an unreachable distance
.
Distance -
This setting determines the distance the press
travels following the weld process. Depending on the mo-
tion control mode, the user defined force or speed will be
applied to the part. A user specified maximum time prevents
infinite holding due to an unreachable distance.

Hold Distance
- The distance the press head travels
following the weld process.
Dynamic Hold Speed
- The speed at which the press
head travels until the user specified distance is met.
Max Hold Time
- The maximum amount of time the
press will apply pressure to the part during the hold
process.
Disabled -
This setting disables dynamic hold and its op-
tions.
