Note<br />
Note<br />
1. Obtain PID parameter values from the above method, set the PID parameters, and<br />
tune in the PID parameter values exactly.<br />
2. PID parameter values obtained from the above method may not be optimum values if<br />
the friction factor of the mechanical system is large.<br />

Manual Adjustments<br />
Take the following steps to adjust the PID parameter values of the Inverter<br />
performing PID control by measuring the response waveform.<br />
Set n084 to 2 or 1 so that the Inverter will perform PID control.<br />
Increase the proportional gain with n086 within a range causing no vibration.<br />
Increase the integral time with n087 within a range causing no vibration.<br />
Increase the differential time with n088 within a range causing no vibration.
