The total number of points available for data recording is given by the Data Recorder Max Points
parameter, ID 0x16000200. The controller allocates these points in equal shares to the available
tables (i.e. to the number of tables given in the TNR? answer). For the E-727, the total number of
points is 262144. If, for example, TNR? replies 8, each table is comprised of 32768 points.
The data recorder sampling period can be read with the RTR? command. The answer gives the
value of the Data Recorder Table Rate parameter (ID 0x16000000) whose default value is one
servo cycle. You can cover longer periods by increasing this value. Use the RTR command or change
the parameter value directly in volatile memory.
