ACS 502 Installation & Start-up Manual G-3
Macro A macro is a pre-programmed set of defaults for all of the parameters, which
are typical for the specified application. When you select a macro from Start-
up Data Parameter B (Applications), you select the macro that most closely
defines the drive functions necessary for your particular application. After
selecting the macro, you can modify or customize the macro to specifically
conform to your application.
Refer to the ACS 500 Adjustable Frequency AC Drives 2 to 350 HP
Programming Manual Including Application Macros for information on
macro applications, functions, and parameter values.
Main A Main is the first of four display levels in the ACS 502/504 programming.
Mains provide access to Groups in the same way that Groups provide access
to Parameters. For example, to access Main 10 while viewing any of the 28
Operating Data Parameters, press [Right Arrow] on the Control Panel
Keypad. From the Main 10 display, press [Up Arrow] to access Main 20,
Main 30, and Main 40. Refer to Chapter 2 – Overview of the ACS 502/504.
Meggar Test A Meggar Test measures an insulation system's resistance. This test passes a
low current, high voltage through a capacitor and measures the resistance of
the insulation system. Meggar test results are usually expressed in megohms.
CAUTION: The ACS 502/504 must not be subjected to testing of this type as
damage could result. Any wires connected to the ACS 502/504 MUST be
disconnected from the ACS 502/504 before being subjected to this type of
test.
Memory The ACS 502/504 memory provides computer storage for program data and
instructions.
Multimeter A multimeter measures electric component functions and values such as
voltage (volts), resistance (ohms), and current (amperes). Some multimeters
also test diodes.
Operating Data Operating Data defines ACS 502/504 Parameters 1 (Output Frequency)
through 28 (Act Value 2 (PFC)) located at the first of four display levels.
Many Operating Data parameters simply display information such as drive
temperature and motor speed, and some parameter values can be changed
according to drive application needs.
Parameter A Parameter is the last of four display levels in the ACS 502/504
programming. In most cases, Groups provide access to Parameters, and
Parameters allow you to modify macros, change start-up settings, and monitor
drive and motor functions. Refer to Chapter 2 – Overview of the ACS 502/
504.
