3-3 Automatic tuning & Test operation
Automatic tuning measures the constants of the connected motor, and automatically adjusts the
parameters so that the system is used to the fullest.
The VT240S automatic tuning function performs different measurements for each of the four control
modes. Carry out automatic tuning each time the motor being used or the applicable control mode is
changed. The automatic tuning mode is set with parameter B19-0 (automatic tuning selection). Refer
detail instruction manual for other control modes.
B19-0 Name
1 Simple adjustment mode for v/f control mode
2 High-function adjustment for v/f control mode
Automatic tuning will automatically change the parameters, so it is recommended to write down
the values set in Table 4-5-2 or Table 4-5-3.
