Appendix 4.4 Transmission delay time of dedicated instructions

The following is the formula to calculate the transmission delay time of dedicated instructions
(time after a dedicated instruction is issued until the execution of the instruction is completed).
(1) Between the master station and an intelligent device station/remote

Appendix 4.5 Calculation formula for operation cycle

The following is the formula to calculate the operation cycle.
Note: The calculation result by this formula is a measure value. Check the actual operation
Operation cycle [μsec] = (7 Ns) + (0.50 Sr) + (32 Na) + 600 + αp
Ns
Na
Sr
αp
device station
(a) Master station
TD1: 0.5 + CT
CT: Operation cycle
Rio: Intelligent device station/remote device station processing time
SM: Master station sequence scan time
m: Number of divided sending = Value that "Data length ÷ 480" is
rounded up to the nearest integer
cycle by parameters and control details to be used.
: Number of slave stations excluding servo amplifiers
: Number of servo amplifiers
: Data size that is actually being link-refreshed [byte]
: Positioning operation cycle [μsec]
Intelligent device station/remote device station
12 m + Rio + SM [ms]
