 TQC Sensorless (Pr. 00-13=2) control diagram is shown in the following:
Load Selection
Settings
 Normal duty: over-load rated output current 160% in 3 seconds (120%, 1 minute). Refer to Pr.
00-17 for the setting for the carrier wave. Refer to Pr. 00-01 or the specification table in Chapter
09 for the rated current.
 In Normal Duty, the default setting of Pr. 06-03 and Pr. 06-04 is 120%, and the maximum setting
range is 160%. However, if DC voltage is higher than 700V
145%.
Carrier Frequency
Settings
 This parameter determinates the PWM carrier frequency for the AC motor drive.

 From the table, you see that the PWM carrier frequency has significant influences on the
electromagnetic noise, the AC motor drive heat dissipation, and the motor acoustic noise.
