5.5.6 Using Macro Mode
A special Macro programming mode is available with the Vacon 500x 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 53
, for detailed information about
using macros to program the Vacon 500x 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 500x 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 Vacon 500x Macro programming mode and configure the following
parameters to the data provided on the nameplate of the motor:
•
ated Volt (509)
•
ated Mtr FLA (510)
•
ated Mtr RPM (511)
•
ower 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.
9. If the test was successful, the drive will stop and return to the configured control path. The “Motor RS”
parameter will contain a new value that is the calculated resistance of the motor.
10. If the test was not successful, the drive will fault with a “RS Meas. Fail” message (Fault 34). If the test
fails, you may want to try the test again with a different “Rated Mtr FLA” or different Current Limit
percentage.
5.6.2 Activating Automatic RS Measurement via Serial Link (Modbus)
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. Configure the following parameters to the data provided on the nameplate of the motor:
•
ated Volt (509)
•
Rated Mtr FLA (510)
•
ated Mtr RPM (511)
•
ower Factor (515)
3. Change
to a value of “Motor RS.” At this point, the RS Measurement will
be armed.
4. Start the RS Measurement by writing a value of 0x0007 to parameter
5. The measurement begins as the drive injects voltage to the motor at zero frequency. The test lasts about
two seconds.
6. If the test was successful, the drive will stop and return to the configured control path. The “Motor RS”
parameter will contain a new value that is the calculated resistance of the motor.
7. If the test was not successful, the drive will fault with a “RS Meas. Fail” message (Fault 34). If the test fails,
you may want to try the test again with a different “Rated Mtr FLA” or different Current Limit percentage.
