This group is used to realize the fixed-length stop function.
The drive inputs counting pulses from the terminal (function 44 for DI4), and obtains
the actual length according to the PPR of the speed measuring shaft (FC.19) and the shaft
circumference (FC.18).
Calculation length = Number of counting pulses/number of pulses per revolution ×
circumference of the measuring shaft.
And correct the calculated length through length ratio (FC.16) and length correction
coefficient (FC.17), to obtain the actual length.
Actual length = calculated length × length ratio ÷ length correction coefficient
When the actual length (FC.15) ≥ the set length (FC.14), the drive will automatically
send a stop command to stop. You need to clear the actual length (FC.15) or modify the
actual length (FC.15) to be < the set length (FC.14) before running again, otherwise it will
not start.
