■Optional data monitor setting
The following table shows data types that can be set.
Data type
Effective load ratio
Load inertia moment ratio
Model control gain
Bus voltage
Encoder multiple revolution counter
Position feedback
Encoder single revolution position
Precautions
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.
Data type
Effective load ratio
Load inertia moment ratio
Model control gain
Bus voltage
Encoder multiple revolution counter
Position feedback
Encoder single revolution position
■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.)
Setting item
[Pr.178] STF terminal function selection
[Pr.179] STR terminal function selection
[Pr.185] JOG terminal function selection
[Pr.449] SSCNET input filter setting
• 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".
Setting item
PD11 Input filter setting
