Chapter 2 – Overview of ACH 500 Programming

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.

Macros

Application Macros

Defined

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.
