2.8 - The PID Tuning Utility

This function is accessible from the terminal window by pressing ALT+C for the Configure pull-down menu and T for

tuning. The Autotuning feature allows finding the PID parameters with virtually no-effort from the user. The parameters are,

in most cases, very close to optimal and in some cases require further fine-tuning by the user.

In this screen press the Page-Up or Page-Down keys on the keyboard to select the motor number.

1) Select the Auto Tune feature. This is the first interaction to find a starting bandwidth parameter.

a) Make sure you read the PEWIN manual section related to the safety issues of this procedure.

b) Perform a DAC calibration if necessary.

c) Select the type of amplifier you are trying to tune.

d) Let the Auto Tune select the bandwidth by checking “Auto Select bandwidth”

e) Do not activate any feed forward parameters in this first pass.

f) Do not activate the integral action component in this first pass.

g) Start the first Auto Tuning interaction. Most likely the motor WILL move after Begin is pressed.
