Normal duty: overload rated output current 150% in 3 seconds. (120%, 1 minute). See Pr.00-17 for the setting for
the carrier frequency. Refer to Chapter 9 Specifications or Pr.00-01 for the rated current.
Heavy duty: overload rated output current 200% in 3 seconds. (150%,1 minute) See Pr.00-17 for the setting for the
carrier frequency. See Chapter 9 Specifications or Pr. 00-01 for the rated current.
Pr.00-01 varies with the setting value of Pr.00-16. The default value and maximum of Pr.06-03 and Pr.06-04 also
vary with the setting value of Pr.00-16.
In normal duty, the default setting of Pr.06-03 and Pr.06-04 is 120%, and the maximum is 150%.
In heavy duty, the default setting of Pr.06-03 and Pr.06-04 is 180%, and the maximum is 200%.
