763 [PID Feedback]
Analog input feedback value received from the transducer position (dancer) or
tension (load cell).
Default:
Min/Max:
0
–/+10000
16-bit
Int
772 [PID Output Sign]
Determines whether the output of the PID regulator is bipolar or positive (clamp of
the negative side).
Default:
Options:
1 =
0 =
1 =
“Bipolar”
“Positive”
“Bipolar”
16-bit
Int
773 [PID Output Scale]
Scale factor for Par 774 [PID Output]. The value of this parameter depends on to
which parameter you want to send the PID regulator output.
Default:
Min/Max:
1.00
–/+100.00
Real 774
774 [PID Output]
Displays the PID regulator output.
Note: This parameter can be assigned to an analog output in order to provide a
cascaded reference in multi-drive systems.
Default:
Min/Max:
Read Only
