L08-38
Fc Reduct dur OL
Temporarily reduces the carrier frequency when
the VFD exceeds a certain level. This temporarily
increases the overload capability (OL2 detection)
allowing the VFD to run through transient load
peaks without faulting.
0–2

0 Disabled
1 Active below 6Hz
Enabled below 6 Hz
Carrier Frequency is reduced when: < 6Hz and
current > 100% of VFD Rated Current, returns to
normal carrier frequency when output current falls
below 88% of VFD rated current or frequency >
7Hz
2 Active @ any Spd
Enabled for the entire speed range
< 6Hz when current > 100% of VFD Rated Current
7Hz when current > 112% of VFD Rated Current
L08-40
FC Reduct Time
Time that the VFD continues running with reduced
carrier frequency after the carrier reduction
condition is gone. Setting L08-40 to 0.00 disables
the carrier frequency reduction time.
0.00–2.00 sec

High Cur Alm Sel
Triggers a high current alarm (HCA) when the
output current rises exceeds 150% of the VFD
rated current.
