Only displayed if a cascade template is selected – see Section 4.2, Basic Configuration/ Template Application.
•2
Not displayed if the associated derivative action time is set to OFF.

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.

Only displayed if a feedforward template is selected – see Section 4.2, Basic Configuration/ Template Application.
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 4.2, 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.
•2
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 when a cascade template is selected.
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
[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. When set to OFF, feedforward action
is disabled.
[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.
