Appendix 3 Compatible Devices with SSCNETIII(/H)
■Optional data monitor setting
The following table shows data types that can be set.
When FR-A700 series is used, each data is delayed for "update delay time + communication cycle" because of the update
cycle of the inverter. The following table shows the update delay time of each data.
■External input signal
Set as the followings to fetch the external input signal (FLS/RLS/DOG) via FR-A700 series.
• Set "1: External input signal of servo amplifier" in "[Pr.116] FLS signal selection", "[Pr.117] RLS signal selection", or "[Pr.118]
DOG signal selection".
• Set the parameters of the inverter as below. (Otherwise, each signal remains OFF.)
• Set the servo parameter of Simple Motion module "Input filter setting (PD11)" to be the same value as the parameter of the
inverter "[Pr.449] SSCNET input filter setting".
