This parameter executes robust tuning (RT).
• When AT or ST is executed with RT selected, PID constants are automat-
ically set which make it hard for control performance to degenerate even
when control object characteristics are changed.
• Even when hunting occurs for PID constants when AT or ST is executed
in normal mode, it is less likely to occur when AT or ST is executed in RT
mode.
Setting range
on: RT function OFF, off: RT function ON
