5.5.4 Restoring Factory Settings
Whenever a parameter’s value is being changed (noted by the P indicator flashing), the original
factory setting for that parameter may be restored by pressing and releasing both the INC or DEC
keys simultaneously and then pressing the ENTER key.
To restore ALL parameters to factory settings, or to recall a previously stored parameter set, see
parameter 801, Program Number (page 99)
.
5.5.5 Viewing Parameters That Have Changed
The X5 unit allows you to view only those parameters that have changed. If you press ENTER and
PROG keys simultaneously, only those parameters that have been changed from the factory defaults
will be shown. Note that all parameters, regardless of Level 1 or 2 default location, will be shown.
If other parameters need to be changed, press the PROG key to exit this mode.
5.5.6 Using Macro Mode
A special Macro programming mode is available with the X5 series of AC drives. The Macro
programming mode allows you to customize the most common parameters for your application in
the Level 1 group. Macro mode provides parameters for activating special features like the program
sequencer or serial communications, plus a means of easily entering important motor parameters.
Parameters that are important to the drive’s operation are also included in the Macro mode. Although
these parameters are also available with standard programming, the Macro mode allows you to
quickly and easily configure the drive with essential parameters.
See
“Chapter 6: Using Macro Mode and Getting a Quick Start” on page 60
, for detailed information
about using macros to program the X5 drive.

Measuring Stator Resistance (RS Measurement)
5.6.1 Activating Automatic RS Measurement via Keypad
1. Make sure there is no load applied to the motor and that the motor shaft is free to spin without
damage or injury.
2. Enter the Macro programming mode of the X5 keypad by pressing and holding the PROG
key until the parameter “Appl Macro” appears on the keypad. This takes about two seconds.
3. Scroll through the parameters of the X5 Macro programming mode and configure the
following parameters to the data provided on the nameplate of the motor:
•
Rated Volt (509)
•
Rated Mtr FLA (510)
•
Rated Mtr RPM (511)
•
Power Factor (515)
4. Change
parameter 519 (Find Mtr Data)
to a value of “Motor RS.” At this point, the RS
Measurement will be armed.
5. Exit the Macro programming mode by pressing the PROG key.
6. The Operate screen shows in two ways that an RS Measurement is ready to be made. First,
the Control path status field displays “MEA.” Second, a “Mtr Measure” warning flashes,
both of these signifying that a measurement is about to be taken.
7. Start the RS Measurement by pressing the FWD key. The measurement can only be made
with the FWD key. The FWD / REV terminals and the REV key will not work.
8. The measurement will begin as the drive injects voltage to the motor at zero frequency. The
test lasts about two seconds.
