Setting or Selection
L8-17 IGBT Protection
Selection at Low
Frequency 0: Conventional
1: Lower fc
Carrier frequency is decreased
when fout 10Hz and the
load is > 100% iac.
2: Short term OL2
OL occurs after 2 seconds
during low speed
[fout 6Hz] current limit.
3: I-Limit=150%
Current limit is set to 150% of
the inverter rated current. Deleted in G7
