Process controller switch−off (PCTRL1−OFF)
The process controller output does not send signals as long as this function is active.
Activation
The function must be linked with a digital input signal under C0410/19.
HIGH level at C0410/19 activates the function.
)
Note!
In addition to the free configuration under C0410 you can also use the fixed
assignment under C0007 to combine the function with a digital input.
Process controller stop (PCTRL1−STOP)
The process controller output is frozen on the current value when the function is activated.
The value remains unchanged until the function is deactivated.
Activation
The function must be linked with a digital input signal under C0410/21.
HIGH level at C0410/21 activates the function.
Integral action component switch−off (PCTRL1−I−OFF)
The process controller output provides the difference between setpoint and actual value,
if necessary with gain V
P
.
ƒ Thus overcontrolled starting and stopping can be avoided. When the controller
operates normally, the integral action component K
I
can be connected.
ƒ Application: e.g. dancer position control
