Patch AMP
Use of the Patch AMP utility requires access to the highest user level, plus
a special second password.
ATTENTION: Altering AMP through the Patch AMP utility
bypasses the system software that checks AMP parameters. You
can enter illegal and/or dangerous values that will not generate
an error. Illegal or dangerous values can cause negative
changes to a machine responding to motion commands. This
can result in damage to the part or the machine, or injury to
an operator.
The Patch AMP utility is softkey selectable; but due to the danger
associated with changing AMP data without any cross-reference checking,
the utility is “double” password protected. Only the highest level user will
see the {PATCH AMP} softkey, and another password must be entered before
that softkey will function.
Important: AMP is typically entered by the system installer and should
not require changes once the control is installed and the machine is
running. Most users should not be permitted access to AMP parameters.
The Patch AMP utility is used to modify the Adjustable Machine
Parameters (AMP) directly on the control. This gives the machine tool
builder the flexibility to change AMP without connecting an ODS
workstation (personal computer) to the control.
Important: For Dual Process controls, Patch AMP is independent of the
selected process. It shows parameters for both processes at the same time.
