Operation procedure of automatic tuning
1. Switch to automatic tuning function
Select “A0 to A3” with “P106: PID Control Mode” and press
button to set the data.
2. Enter measurement ready status
Press button to enter measurement ready status.
3. Automatic tuning starts
Turn run command ON, and automatic tuning will start.
(The displaying part will flicker.)
*The inverter will drive the motor automatically.
4. Automatic tuning completes
When automatic tuning completes, “End” will be displayed
after measured data are written to parameter P107 to
P109 automatically, indicating that automatic tuning is
complete.
After that, data of parameter P106 will be automatically
changed to PID operation mode without automatic tuning
function.
(When performed with “A0”, “A1” and “A2”, the data will be
changed to “0”, “1” and “2” respectively.)
5. Enter operation ready status (normal stop status)
Turn stop command ON and enter operation ready status.
After that, normal operation can be performed.
*PID control status can be monitored in control state monitor (n14 to n17).
・
Depending on different processes, automatic tuning may not be performed.
In this case, automatic tuning will stop with “Err” displayed and setting value of
each parameter will remain unchanged. “Err” can be reset after stop
command is turned ON to switch to normal stop status.
・
After multi-speed signal is input, PID control will be terminated to perform
multi-speed operation.
・
After JOG signal is input, PID control will not be performed.
・
After PWM signal is selected, PID control will not be performed.
