(Link scan time/timeout time )
*1 Reference response time refers to the time taken by the servo amplifier to return a response to the master station after receiving a
command from the master station.
*2 Calculate the link scan time as follows. Also, use the reference response time for Ns.
MELSEC iQ-R/MELSEC-Q/L: Ls = Ns + Nm
MELSEC iQ-F: Ls = SM + {(Ns + Nm)/SM}
Ls: Link scan time, Ns: Response time of slave station, Nm: Request time of master station, SM: Sequence scan time
*3 Check the current link scan time (when all the slave stations are in a normal state) using the CC-Link IE Field Network Basic diagnosis
function. Then, set the timeout time approximately 5 times the link scan time (example: 50 ms when the current link scan time is 10 ms).
