RAMP Function Block does not work when I use Time parameter

Hi Folks

I am using the RAMP function to close my PID controller to 0% in 20 seconds

The RAMP output is connected to Track_Val of PID controller.

See the attached configuration. When I am using the time function, the ramp function does not work and the controller does not go to 0%.

When I am using the rate function and set a particular Rate of closing in the RAMP function block, the controller does go to 0%

I am attaching my Module configuration.

Has anyone faced a similar issue before wherein the RAMP function works by selecting the Rate parameter but not with Time parameter?
