Derivative Action Time 2
[0.1 to 999.9 seconds or '
OFF
']
The derivative action time for the slave controller if a cascade template is
selected – see Section 5.2, Control Configuration/ Template Application.
Approach Band 1
[0.1 to 3.0 proportional bands]
This parameter limits when derivative action time 1 is applied. When the
process variable is outside the approach band, derivative action is not applied.
Approach Band 2
[0.1 to 3.0 proportional bands]
This parameter limits when derivative action time 2 is applied to the
slave control loop.
Manual Reset Value 1
The value applied to bring the master control output to the zero error
point under normal load conditions (integral action disabled) or the
offset applied to the control output (integral action enabled).
[0.0 to 100%]
Note. Manual reset is applied whether or not an integral action
time is set.
Manual Reset Value 2
As Manual Reset Value 1, but applied to the slave output.
[0.0 to 100%]
Note. Manual reset is applied whether or not an integral action
time is set.
Feedforward Gain
The feedforward value applied to the control output is:
(disturbance variable x feedforward gain) + bias
[0.1 to 999.9 or '
OFF
']
Note. The feedforward value is normally added to the PID output.
Using the PC Configurator, the value can also be multiplied by the PID output.

Level 2 – Tune
•1
Displayed only if a cascade template is selected – see Section 5.2, Basic Configuration/ Template Application.
•2
Not displayed if the associated derivative action time is set to
OFF
.
•3
If manual control is selected and no integral action time is set, the manual reset value is calculated
automatically to give bumpless transfer into auto control.
•4
Displayed only if a feedforward template is selected – see Section 5.2, Basic Configuration/ Template Application.
