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 preprogrammed 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
saves the result as a user macro.
The ACS350 has seven standard macros and three user macros. The table below
contains a summary of the macros and describes suitable applications.

Suitable applications
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.
Ordinary speed control applications where no, one, two or three constant speeds
are used. The drive is started and stopped with push buttons.
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).
Speed control applications where no or one constant speed is used. The speed is
controlled by two digital inputs (increase / decrease / keep unchanged).
Speed control applications where switching between two control devices is
needed. Some control signal terminals are reserved to one device, the rest for the
other. One digital input selects between the terminals (devices) in use.
Process control applications, e.g. 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.
Torque control applications. It is possible to switch between torque and speed
control: Some control signal terminals are reserved to torque control, others for
speed control. One digital input selects between torque and speed control.
The user can save the customised standard macro, i.e. the parameter settings
including group 99 START-UP
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.
