Speed control under Real sensorless vector control, vector control, PM sensorless vector control
● The torque limit using analog input can be corrected with the calibration parameters C16 (Pr. 919)
to C19 (Pr. 920), and C38 (Pr. 932) to C41 (Pr. 933). (Refer to page 5-426.)

Fig. 5-16:
NOTE When inputting an analog signal to the terminal 1, input a positive voltage (0 V to +10 V (+5 V)).
When a negative voltage (0 V to -10 V (-5 V)) is input, the torque limit value set by the analog signal
becomes "0".
