3.The high-speed analog sampling function stops when the specified num- ber of high-speed analog input data samples have been collected.

The following diagram shows how this method can be used to collect dis- placement data from a particular workpiece position.

The sampled data can be processed to calculate and store the average, max- imum, and minimum values in multiple ranges specified. A judgement output can also be generated.

7-10-2	Outline

The FQM1-MMA21 Motion Control Module can generate analog output sig- nals for two ports. Each output can be set independently to one of four signal types: −10 to +10 V, 0 to 10 V, 0 to 5 V, or 1 to 5 V.

Normally, the analog values stored in A560 and A561 are output cyclically during END refreshing, but the outputs values can also be immediately refreshed with the SPED(885) instruction for step-pattern outputs or the ACC(888) instruction for sloped outputs.
