Defines the target value for
the control.
Note:The range is subject to
the restrictions imposed
by setting the
measurement range lower
and upper limits of the
parameter.
See PG10 on page 79.
Sets the soft start time so
that a new setting is
implemented gradually.
* A value of 0.00 sets the soft
start to OFF.
* This item is shown when
SSL=0 in PG10.
Places restrictions on the
amount of change for each
unit of time when settings
are changed.
* A value of 0 sets the setting
change rate limiter to OFF.
* This item is displayed when
SSL=1 in PG10.
Sets an alarm value.
* The type of alarm is selected
by the parameter settings.
See PG04 on page73.
Sets proportional band for
the control output.
* A value of 0.0 sets On and
Off actions.
* In the heating, cooling PID
operation, a value of 0.0 sets
On and Off actions for both
heating and cooling.
