Application macros 10710Application macrosWhat this chapter containsThe chapter describes the application macros. For each macro, there is a wiringdiagram showing the default control connections (digital and analog I/O). The chapteralso explains how to save a user macro and how to recall it.Overview of macrosApplication 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 thepurpose - with parameter 9902 APPLIC MACRO, makes the essential changes andsaves the result as a user macro.The ACS355 has eight standard macros and three user macros. The table belowcontains a summary of the macros and describes suitable applications.Macro Suitable applicationsABB standard Ordinary speed control applications where no, one, two or three constantspeeds are used. Start/stop is controlled with one digital input (level startand stop). It is possible to switch between two acceleration anddeceleration times.3-wire Ordinary speed control applications where no, one, two or three constantspeeds are used. The drive is started and stopped with push buttons.Alternate Speed control applications where no, one, two or three constant speedsare used. Start, stop and direction are controlled by two digital inputs(combination of the input states determines the operation).MotorpotentiometerSpeed control applications where no or one constant speed is used. Thespeed is controlled by two digital inputs (increase / decrease / keepunchanged).
