ACS 501 Installation & Start-up Manual
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.
A Main is the first of four display levels in the ACS 501 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 501.
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 501 must not be subjected to testing of this type as
damage could result. Any wires connected to the ACS 501 MUST be
disconnected from the ACS 501 before being subjected to this type of test.
The ACS 501 memory provides computer storage for program data and
instructions.
A multimeter measures electric component functions and values such as
voltage (volts), resistance (ohms), and current (amperes). Some multimeters
also test the condition of diodes.
Operating Data defines ACS 501 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.
A Parameter is the last of four display levels in the ACS 501 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 501.
