Description
Displays the process control feedback signal value used
for the PI controller.
This parameter is read-only.
PI feedback.
Displays the process control set point reference signal
ramped value used for the PI control.
This parameter is read-only.
PI setpoint.
Displays the process control error which is effectively
the difference between ramped set point reference
and process feedback signal.
This parameter is read-only.
PI error.
Displays the content of the PI output P-term
component.
This parameter is read-only.
P term.
Displays the content of the PI output I-term component.
This parameter is read-only.
I term.
Displays the output of the PI controller in % of the
speed range defined for the automatic process control.
This parameter is read-only.
PI output.
Displays the actual value of the feedback signal selected
for process 1.
This parameter is read-only.
Process 1 feedback signal.
Displays the actual value of the feedback signal selected
for process 2.
This parameter is read-only.
Process 2 feedback signal.
Displays the status word of the functions controlling
ESP control program starting routines, i.e. Starting
speed, Acceleration assistance, Kick-start and Current
pulse-start.
No auto mode process control is active.
Auto mode Process 1 closed loop control is active.
Auto mode Process 2 closed loop control is active.
PI output is at maximum limit.
PI output is at minimum limit.
