* Initial value is dependent on VFD size, which is determined by O02-04 (kVA selection)
** Initial value is dependent on carrier. 2kHz = 0, else 1

L08-19 Fc Red dur OHAlm Specifies the frequency reference reduction gain
at overheat pre-alarm when L08-03 = 4.

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 tripping.

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
Sets the 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 A01-02
L08-41 High Cur Alm Sel Triggers a high current alarm (HCA) when the
output current rises exceeds 150% of the VFD
rated current.

L08-55 DB Tr protection Internal Braking Transistor Protection 0, 1 0*
0 Disabled Disable braking transistor protection when not
using the internal braking transistor.
1 Enabled Enable when connecting a braking resistor to built-
in braking transistor.
