76 H9 ASD Installation and Operation Manual
Direct Access Parameter Information
The H9 ASD has the ability to allow the user direct access to the motor control functions. There are two
ways in which the motor-control parameters may be accessed for modification: Program ⇒ applicable
menu path or Program ⇒ Direct Access ⇒ applicable parameter number. Both methods access the
parameter via the Program mode. Once accessed, the parameter may be viewed or changed.
The Program mode allows the user to develop an application-specific motor-control profile. Motor
control functions may be set to accommodate specific power and timing requirements for a given
application. The configurable parameters of the Program mode that have user-accessible Parameter
Numbers are listed and described below.
Note: Parameter selections are preceded by the number used to select an item if using communications to
write to a parameter location in memory (i.e., F000
⇒ 0-Manual, 1- No Trip on Acc/Dec, 2-No trip on
Acc Only, etc.).
Note: The setup procedures included within this section may require a Reset before performing the procedure.
Application-specific settings may then be performed. The pre-Reset conditions may be saved (see
F007).
Note: Communications setting changes will require that the power be removed and then re-applied for the
changes to take affect.
Direct Access Parameters/Numbers
