Note: Read the PID parameter notes in the SV01 manual, section 4.5.4 before attempting to use the drive for PID control.
PID Mode Operation
Normal-acting PID control will command a decrease in motor speed in response to an increasing process variable feedback. An example of normal PID mode is a direct acting system that maintains duct pressure. Duct pressure is the process variable that is monitored by the feedback device. As duct pressure rises, motor speed will decrease to maintain the pressure.
Reverse acting PID control will command an increase in motor speed in response to an increasing process variable feedback. An example of reverse PID mode is a reverse acting system that maintains water temperature in a cooling tank. Water temperature is the process variable that is monitored by the feedback device. As water temperature rises, motor speed needs to be increased to pump more cold water and thereby lowers the temperature in the tank.
