Standard function blocks

What this chapter contains

This chapter describes the standard function blocks. The blocks are grouped
according to the grouping in the DriveSPC tool.
The number in brackets in the standard block heading is the block number.
Note: The given execution times may vary depending on the drive application used.
The block execution time describes how much CPU load
block reserves. For example, if a block with the execution time of 2.33 µs is set to a
1 ms time level, the increase in the CPU load will be 0.23%.
