6. Carrier Frequency and Rated Current Derating
The settings of A1-02 [Control Method Selection], C6-01 [Normal / Heavy Duty Selection], and C6-02 [Carrier Frequency
Selection] determine the rated current derating. Also, it may be different between the V1000 and GA500 depending on the
capacity.
If the capacity is such that the rated current is lower with the GA500 than with the V1000 (hatched in the table below), the
carrier frequency should be lowered or the GA500 capacity should be increased.
Comparison of rated output current (A): V1000 versus GA500
V1000: A1-02=0, 2, 5
GA500: A1-02=0, 2, 5
