ACH 500 Programming Manual
This chapter defines Application macros in terms of parameter settings and
describes how to use the menu system of parameters to select and modify the
macros.
Application macros are pre-programmed parameter sets. You'll use them to
start the ACH 500 quickly and easily.
Application macros minimize the number of different parameters to be set
during start-up. All parameters have factory-set default values. The HVAC
macro program is the factory-set default macro.
While starting up the ACH 500, you can specify a macro as the base setting
for a drive. You can select any one of the following macros from Start-up Data
Parameter B (Applications):
• HVAC
• FLOAT PT.
• HVAC – PI
• Pump and Fan
In addition to these application macros, there is a User macro. The User
macro allows the user to save the existing parameter settings for recall at a
later time.
Macro programs do not usually set all parameter values exactly as needed for
a special application. Check frequency limits and acceleration/deceleration
times and modify as required for your application.
You may need to modify digital and analog inputs and/or outputs. The
Parameter Settings tables in Chapter 5 – Standard Application Macro
Programs indicate parameters you may have to modify. These parameters are
indicated in the tables with an arrow ( ) symbol.
