8.2 Data Sampling
The NC internal data (speed output from NC to amplifier, or feedback data from amplifier, etc.) can be
sampled and output serially.
(Setup parameter "#1224 aux08/bit0" must be set to "1" to use this function.)
8.2.1 Specifications
• Sampling cycle : 3.5ms ∗ scale
• Number of sampled axes : 1 to 18 axes (Servo axes ∗ 14 + spindle ∗ 4)
• Number of sampled points : 1 to 8 points
• Number of sampled data items : With no memory cassette ... Max. 3,072
When using HR412/HR452 (512KB) ... Max. 131,072
When using HR422/HR462 (1MB) ... Max. 262,144
When using HR432/HR472 (2MB) ... Max. 524,288
(Note 1) The memory cassette is mounted in CBUS#1.
(Note 2) The maximum number of sampled data items is the number of all sampled points. When the data
to be sampled increases, the number of sampled points will drop per data item.
[Restrictions]
(1) When using this function, do not use the input/output functions (PLC, APLC, MELDASNET or
anshin-net) or the onboard.
(2) If the machining program is longer than 1280m or if APLC is added, the memory cassette cannot be
designated.
(3) If a memory cassette is mounted in CBUS#1 for a purpose other than data sampling (to run APLC on
the SRAM, etc.), the expansion memory cannot be used to sample the data.
(4) The data set with this function is not output to the parameters.
(5) When the power is turned ON, "#0 Sampling start" will be set to "0" (sampling stop).
(The data set in #1 to #27 will be held.)
