FAQ: I want the motor never to run below a certain speed and I am using PID, but there may be times when this low speed will be "too much". Is there a solution for this?

The GPD506/P5 has a feature called the "Sleep" function. This is commonly used when a pump is being utilized that cannot run below a certain speed without incurring damage to itself. Simply enter the desired "minimum" speed into parameter n094 along with the desired delay time (if any) in parameter n095. If the PID loop calls for an output lower than the value in n094, the output will go to zero until the PID loop calls for an output higher than n094. This feature can only be used when PID is enabled.
