Load Selection
Factory Setting: Ready only
Settings 1: Heavy load
 Heavy duty: over load rated output current 200 % in 3 seconds. (150 %,1 minutes) Please refer to
Pr. 00-17 for the setting of carrier wave. Refer to Pr. 00-01 or specification table for the rated
current.
 In Heavy Duty, the default setting of Pr. 06-03 and Pr. 06-04 is 180 %, maximum is 200 %.
However, if DC voltage is higher than 700 VDC (460V series) or 350V (230V series), then the
maximum will be 165 %
Carrier Frequency
Factory Setting: 6
Settings Heavy load: 2~15 KHz
 This parameter determinates the PWM carrier frequency of the AC motor drive.
