3.1.1 Steps for Programming the Drive for PID

Please read the PID Parameter notes in the manual Section 4.5.4.
1. To activate PID mode, one of the TB-13x inputs (controlled with parameters 121 thru 124) must be used to select
the "Auto reference" that will become your desired set point reference. For example to have TB13A select the
keypad as the reference set P121 to 06. The setpoint reference can be anything from keypad, 0-10V, 4-20mA
or a preset speed. However, it cannot be the same source as the feed-back itself.
2. Set P200 to 1 for normal acting or 2 for reverse acting.
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.
3. Set P201 to 0 to select the 4-20 mA feed-back source or 1 to select 0-10vdc.
4. Set P204 and P205 to transducer's minimum and maximum feedback values.
Example: Transducer rating = 0-300PSI; P204 = 0.0, P205 = 300

Speed at maximum signal sets the speed the drive
will run the motor when it sees 10VDC from the pot.
Speed at minimum signal sets the speed the drive
will run the motor when it sees 0VDC from the pot.
