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 selects the macro best suited for the purpose with parameter
9902 APPLIC
MACRO, makes the essential changes and saves the result as a user macro.
The ACS150 has six 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).
Hand/Auto
Speed control applications where switching between two control devices is
needed. Some control signal terminals are reserved for one device, the rest for
the other. One digital input selects between the terminals (devices) in use.
PID control Process control applications, for example, different closed loop control systems
such as pressure control, level control and flow control. It is possible to switch
between process and speed control: Some control signal terminals are reserved
for process control, others for speed control. One digital input selects between
process and speed control.
User The user can save the customised standard macro, that is the parameter settings,
including group
99 START-UP DATA , into the permanent memory, and recall the
data at a later time.
For example, three user macros can be used when switching between three
different motors is required.
