10. Results of the reflash are shown in the display, and depending on the results, you will see different
things. If the reflash is successful, the Vacon 500x software will show the normal Vacon 500x display. If
unsuccessful, the following screen appears:
The number after “Request Failed” tells why the failure occurred:
0 = User aborted process
1 = Cannot open file
2 = Corrupted file
11. Press the STOP key to reset the Bootloader.
5.8 Using the Keeper Data Log
The Vacon 500x provides a data collection utility called the “Keeper.” This function accumulates time-
based data during a specific period of time. For example, you might need to determine how many gallons
of liquid have been pumped, how many feet of material have been processed, or how many “widgets” have
been produced in a given time period. The Keeper collects this kind of data for you, in 8-, 12-, or 24-hour
periods of time. The Keeper also logs the kilowatt hours the drive has delivered to the motor during the
recording period, which can help you determine peak energy times for your process.
To use the Keeper, you need to attach a sensor to an analog input or to the encoder feedback signals. The
sensor should provide a signal that represents the rate at which you are performing a task. The signal
should be compatible with the input range of the analog input or encoder. Set up a few parameters that
tell the drive the input scaling of the sensor, the rate information, and the times in which you want to
capture the data, and the Keeper does the rest. The data can be stored and retrieved on a USB flash
memory device, in a .csv file format that makes it possible to import directly into a spreadsheet. See
“Storing Keeper Files” on page 47 for instructions on how to store Keeper data on a USB memory stick.
5.8.1 Keeper Parameters
The following table shows the Keeper parameters and a brief description of their functions. For their
options and defaults, please refer to
page 70 .
The maximum number of records that the Keeper can store before data is overwritten is 128. If you select
“24 Hour” as the rate, you can keep 128 days of information; “12 Hour” allows 64 days; “8 Hour” allows 32
days.
5.8.2 Setting up the Keeper Function
To set up the Keeper function, follow these steps:
Parameter Parameter Name Description
380 Keeper Input Cfg
Configures how the Keeper function gets its input and also enables
the Keeper function.
381 Keeper Max Scale
Configures the value of the Keeper input signal when the analog input
is at its maximum value.
382 Keeper Save Time
Sets the time of each day that the Keeper will save an accumulated
process variable.
384 Keeper Save Rate
Configures whether the Keeper will collect multiple records during a
day.
385 Keeper Input Provides feedback to display the current value of the Keeper input.
386 Keeper Time Rate
Configures the time base of the Keeper accumulation. The setting of
this variable is dependent on the process variable.
387 Keeper Rec. Num Shows how many records have been saved by the Keeper.
388 Active Kpr Rec. Shows the active Keeper record.
389 Keeper Units Configures the units of the Keeper input.
