Setpoint in process unit that
0.00 1640 can be selected as setpoint
source (parameters).
Setpoint in process unit that
0.00 1641 can be selected as setpoint
source (parameters).
Sometimes we don't want
to make fast step changes
in the
might upset the process.
Then we can set a ramping
time for the setpoint. The
time set with this parameter
0.00 1642
is the time it takes for the set-
point to change from 0% to
100%. NOTICE! When start-
ing the drive the setpoint
will always ramp from the
feedback value to the set-
point.
Select from where we should
take the signal for this set-
1 1643 point.
Notice! ProcessDataIn uses
two decimals as format.

Description
Dead band around the
setpoint. When we are
within this area
the PID
controller output will be
locked. The size of the Dead
Band area around the set-
point is set in process units.
I.e. 2 bar will give us a dead
band of +- 2bar around the
setpoint.
We can also set a delay
