Temperature controllers incorporating full PID control loops allow great flexibility in optimizing the instrument for widely varying operating conditions. This flexibility comes at the price of time required for setup. Typically, several minutes to several hours are required to determine the PID constants needed for optimum system operation. Even with an auto-tune feature, 45 minutes or more may be needed to complete the auto-tune process for a single temperature setpoint. The purpose of this tech note is to provide the LDT-5900 user a collection of Proportional, Integral, and Derivative (PID) values that may be used with standard ILX Lightwave laser diode mounting fixtures. These values will allow the user to begin testing almost immediately upon connecting the equipment together and applying power.
