Position Watch n Detect Input
Provides position feedback source for the position watch function. The position watch
function is enabled and configured by the position control configuration P721 [Position
Control]. The position watch function compares this value to the position watch set
point P747 [PsnWatch1 Stpt], P750 [PsnWatch2 Stpt] when this parameter P746, P749
is selected by the position watch select P745 [PsnWatch1 Select], P748 [PsnWatch2
Select]. The position detect bit P724 [Psn Reg Status] Bit 9 “PsnW1Detect”, Bit 10
“PsnW2Detect” is set when the appropriate condition is satisfied.

Position Watch n Setpoint
Provides set point for the position watch function. The position watch function is
enabled and configured by P721 [Position Control]. The position watch function
compares this value to the position feedback source selected by the position watch
select P745 [PsnWatch1 Select], P748 [PsnWatch2 Select]. The position detect bit P724
