The data log function saves drive status information as a CSV file in the microSD memory card in the keypad. Monitors Ux-xx are the source of data log information.
There are two types of data log functions:
-
Long-term data log: Saves data continuously over an extended time period.
-
Short-term data log: Saves data over a set length of time before and after the drive detects a trigger event with a short sampling cycle.
You can record a maximum of 10 monitors for long-term data logs and a maximum of four monitors for short-term data logs.
Table 1 shows the keypads that support the short-term data log function.
Note:
-
The short-term data log function is available in drive software versions PRG: 01034 and later.
-
The “PRG” column on the nameplate on the right side of the drive identifies the software version. You can also use U1-25 [SoftwareNumber Flash] to identify the software version.
