Application macros 107
Application macros
What this chapter contains
The chapter describes the application macros. For each macro, there is a wiring
diagram showing the default control connections (digital and analog I/O). The chapter
also explains how to save a user macro and how to recall it.
Overview of macros
Application macros are pre-programmed parameter sets. While starting up the drive,
the user typically selects one of the macros - the one that is best suited for the
purpose - with parameter 9902 APPLIC MACRO, makes the essential changes and
saves the result as a user macro.
The ACS355 has eight standard macros and three user macros. The table below
contains a summary of the macros and describes suitable applications.
Macro Suitable applications
ABB standard Ordinary speed control applications where no, one, two or three constant
speeds are used. Start/stop is controlled with one digital input (level start
and stop). It is possible to switch between two acceleration and
deceleration times.
3-wire Ordinary speed control applications where no, one, two or three constant
speeds are used. The drive is started and stopped with push buttons.
Alternate Speed control applications where no, one, two or three constant speeds
are used. Start, stop and direction are controlled by two digital inputs
(combination of the input states determines the operation).
Motor
potentiometer
Speed control applications where no or one constant speed is used. The
speed is controlled by two digital inputs (increase / decrease / keep
unchanged).
