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:
•
Rated Volt (509)
•
Rated Mtr FLA (510)
•
Rated Mtr RPM (511)
•
Power Factor (515)
3. Change
519 (Find Mtr Data)
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.

Storing Data and Reflashing Using a Flash Memory Device
You can use a flash memory stick (sometimes called a
jump drive, thumb drive, or flash drive) with the USB port
on the X5. In this way, software, program parameters and
Keeper data can be stored easily. The file type for drive
parameters is the same as used by PDA-trAC Plus with an
extension of
.tps
. When stored, the file is identified with
794
. Keeper data files
have an extension of
.csv
.
5.7.1 Storing Drive Parameters
1. Insert the memory stick in the USB port.
2. Access
799
(Config USB Mode)
in
Level 2 programming.
3. Select
Par. Store
and press the
INC
key.
4. The display indicates the file name that will be
stored and that you should press
SHIFT
to proceed.
5. Follow the prompts on the screen and when the
memory write is complete, the display indicates that you should press the
DEC
key to finish.
