ASR PI controller can be transferred to P controller depending on the status of the multi-function terminal input set
as ’
ASR P/PI transfer
’.

ASR P/PI Sel
To avoid the shock to the control system due to the rapid change P and I gain in case of ASR gain transfer, if the
multi-function terminal input set to ‘
ASR Gain Sel
’ is ‘On’, the transferred P gain changes gradually for the time set at
CON_09. P gain 2 is transferred to P gain 1 at the higher speed than the value set at CON_10. This happens when the
multi-function terminal input set to ‘ASR Gain Sel’ is ‘On’, not ‘Off”
