If the value of the parameter is set
to 100% a change of 10% in the
error value causes the controller
output to change by 10%.

If this parameter is set to 1,00s a
change of 10% in the error value
causes the controller output to
change by 10.00%/s.

If this parameter is set to 1,00s a
change of 10% in the error value
during 1.00 s causes the controller
output to change by 10.00%.

Value in Process units at 0% feed-

This scaling is done for monitoring
purpose only. The PID controller
still uses the percentage internally
for feedbacks and setpoints.

put is locked if the feedback stays
within the deadband area for a
predefined time.

If the feedback stays within the
dead band area for a predefined
time, the output is locked.
