Limitation
- Data update cycle
Position-related data is updated at intervals of 1 ms, and power-related
data is updated at the current cycle. Therefore, even if you specify a
sampling cycle that is shorter than the data update cycle, the displayed
data remains unchanged during the present data update cycle.
- Sampling cycle and the number of channels measured
Regarding the sampling cycle and the number of channels measured,
there are limitations as shown in Table 12.5.1.1(l).
Table 1.9.1.1 (q) Sampling cycle and the number of channels measured

(Channel 3 or later cannot be input.)
The following limitations are imposed on the servo axis and spindle
axis.
Number of channels that can be acquired per servo DSP
• Up to four channels can be acquired when the sampling
cycle is 1 ms or longer, 500 µs, or 250 µs.
• Up to two channels can be acquired when the sampling
cycle is 125 µs.
• Only one channel can be acquired when the sampling cycle
is 62.25 µs.
Number of channels that can be acquired per spindle axis
• Up to two channels can be acquired when the sampling
cycle is1 ms or longer.
• Only one channel can be acquired when the sampling cycle
is 500 ms.
