4.7. Control Mode Setting
By setting the Pr. 370 "control mode selection" value, you can choose any of PLG feedback control (V/F control,
advanced magnetic flux vector control) and vector control.
Torque control and position control are not performed. (However, torque limit can be done in the vector control
mode.) When holding torque is required during a stop, choose vector control (zero speed control or servo lock).


Note: 1. When a speed control range of 1:1000 is required, choose vector control.
If vector control has been chosen, torque control and position control are not performed. The frequency
response of vector control is 10 to 20rad/s.
2. When Pr. 80 and Pr. 81 = "9999", PLG feedback control (V/F control) is valid if "1" or "2" is set in Pr. 370.
3. The RT terminal may be used to select between V/F control, PLG feedback control + advanced magnetic
flux vector control and vector control during a stop only.
