Reference response time
(Link scan time/timeout time
*1 The reference response time is the time it takes for the servo amplifier to receive a command from the master station and respond to the
master station.
*2 The link scan time is calculated by the following formula. Use the reference response time for Ns.
For MELSEC iQ-R/MELSEC-Q/L: Ls = Ns + Nm
For MELSEC iQ-F: Ls = SM + {(Ns + Nm)/SM}
Ls: Link scan time, Ns: Slave station response time, Nm: Master station request time, SM: Sequence scan time
*3 Check the current link scan time (when all slave stations are normal) with CC-Link IE Field Network Basic diagnostics, and set the
timeout time to about 5 times the link scan time (50 ms if the current link scan time is 10 ms).
