ACS 502 Installation & Start-up Manual 5-7
Default Drive
Parameters
Now that you have tested and started the drive using the Factory macro
settings, check the Factory macro default drive parameters. Refer to the ACS
500 Adjustable Frequency AC Drives 2 to 350 HP Programming Manual
Including Application Macros for additional information about Factory macro
default settings.
ACS 502 external control wiring schemes vary according to the macro you
choose and the parameter values you change. If you plan to change the ACS
502 macros or parameter values, and if you plan to use an external control
device, refer to the ACS 500 Adjustable Frequency AC Drives 2 to 350 HP
Programming Manual Including Application Macros for information on
control wiring, application macros, and modifying macro parameters.
To complete the start-up, select the appropriate application macro, and make
any necessary parameter changes. Connect all external wiring based on the
configuration selected, and test all external interfacing.
Customizing
Application Macro
Parameters
At some point during the installation of your ACS 502 you may select one of
the pre-set application macros closely suited to your application. You select
application macros from Start-up Data Parameter B (Applications). You also
may need to modify the macro to custom-fit your application. For example, if
you select the Factory macro for your application, the Factory macro default
for Start-up Data Parameter D (Supply Voltage) is 480 V. If your supply
voltage is 460 V, you need to change this parameter in the macro accordingly.
To customize the macro for your application you must change certain
parameter values. In each macro, certain parameters are more likely to be
changed than other parameters, but the application determines which
parameters, and in which macro, changes will be required.
Note: If you plan to use an external control device for your drive, you must
wire the control to the drive according to the wiring scheme of the
macro you select. Refer to the ACS 500 Adjustable Frequency AC
Drives 2 to 350 HP Programming Manual Including Application
Macros for more information on specific macro external control wiring
schemes.
Refer to the ACS 500 Adjustable Frequency AC Drives 2 to 350 HP
Programming Manual Including Application Macros for more information on
accessing and changing parameters.
Note: If you use
RUN ENABLE
Digital Input from the screw terminals, the
keypad’s
START/STOP
function becomes disabled until a run enable
signal is present.
Note: The direction is fixed in
FORWARD
by Parameter 10.1.3 (Loc/Ext
Direction) in the factory default settings for safety purposes. If the
application requires reversing, change Parameter 10.1.3 accordingly.
If reversing is not required, the digital input programmed for Direction
can be reprogrammed for another function.
