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 and DEC keys simul-
taneously and then pressing the ENTER key.
To restore ALL parameters to factory settings, or to recall a previously stored parameter set, see param-
eter 801, Program Number (page 83).
5.5.5 Viewing Parameters That Have Changed
The Vacon 50X unit allows you to view only those parameters that have changed. If you press the 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 in either Level 1 or 2, as needed.
5.5.6 Using Macro Mode
A special Macro programming mode is available with the Vacon 50X series of AC drives. The Macro pro-
gramming mode allows you to customize the most common parameters for your application in the Level
1 group. Macro mode provides special parameters for activating modes of operation by macros, program
sequencer, or serial communications.
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 “Using Macro Mode and Getting a Quick Start” on page 49, for detailed information about using mac-
ros to program the Vacon 50X drive.
5.6 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 Vacon 50X keypad by pressing and hold-
ing the PROG key until the parameter “Appl Macro” appears on the keypad. This
takes about two seconds.
3. Scroll through the parameters of the Vacon 50X Macro programming mode and
configure the following parameters to the data provided on the nameplate of the
motor:
• Rated Mtr Volt (509)
• Rated Mtr FLA (510)
• Rated Mtr RPM (511)
• Power Factor (515)
4. Change parameter “Find Mtr Data” (519) 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 fre-
quency. The test lasts about two seconds.
