• Equation Format – Specify the equation format of the
controller.
• Derivative Input – Specify the derivative input of the
controller.
• Sampling Period – Specify the sampling period of the
controller. The period must be greater then zero and is the

• Parameter b – Select the value of the parameter b entering
the term of the PIDC equation. The value
of the parameter ranges from 0 to 1.
• Dead Band – Click the check box to activate the dead
band of the controller and specify the dead band radius
and dead band type.
• Dead Band Radius – If the Dead Band check box is
checked, enter the dead band radius of the controller. This
value must be greater then zero.
• Dead Band Type – If the Dead Band check box is
checked, enter the dead band type of the controller.
• Output Limiting with AntiReset WindUp – Click the check
box to enable this function, and specify the upper and
lower limits.
• Minimum – When the Output Limiting check box is
checked, enter the lower saturation limit of the controller
output.
• Maximum – When the Output Limiting check box is
checked, enter the upper saturation limit of the controller
output.
IMPORTANT
The minimum value must be always lower then the maximum
value.
