L8-11
(04B7)
Heatsink Fan Off-Delay
Time
Sets the length of time that the drive will wait before it stops the cooling fan after it cancels the Run
command when
L8-10 = 0 [Heatsink Cooling Fan Ope Select = Dur Run (OffDly)]
.

Ambient Temperature
Setting
Sets the ambient temperature of the drive installation area.
40 °C
(-10 - +50 °C)
The
drive
automatically
adjusts
the
drive
rated
current
to
the
best
value
as
specified
by
the
set
temperature.
Set
the

where
you
install
the
drive
to
a
value
that
is
more
than
the
drive
rating.

L8-15: Drive oL2 @ Low Speed Protection
No.
(Hex.)
Name
Description
Default
(Range)
L8-15
(04BB)
Drive oL2 @ Low Speed
Protection
Sets the function to decrease drive overload at low speeds to prevent damage to the main circuit
transistor during low speed operation (at 6 Hz or slower) to prevent
oL2 [Drive Overloaded]
.
1
(0, 1)
Note:
Contact Yaskawa or your nearest sales representative for consultation before disabling this function at low speeds. Frequent operation of
drives under conditions of high output current in low speed ranges may shorten the service life of the drive IGBT due to heat stress.
0 : Disabled (No Additional Derate)
The drive does not decrease the overload protection level.
1 : Enabled (Reduced oL2 Level)
When the drive detects
oL2
during low speed operation, it automatically decreases the overload detection level.
At zero speed, the drive derates the overload by 50%.
■
L8-18: Software Current Limit Selection
No.
(Hex.)
Name
Description
Default
(Range)
L8-18
(04BE)
Software Current Limit
Selection
Set the software current limit selection function to prevent damage to the main circuit transistor
caused by too much current.
0
(0, 1)
0 : Disabled
When the output current is at the software current limit value, the drive does not restrict the output voltage.
Note:
The drive may detect an
oC [Overcurrent]
when loads are particularly heavy or the acceleration time is particularly short.
1 : Enabled
When the output current is at the software current limit value, the drive decreases output voltage to decrease output
current.
When the output current decreases to the software current limit level, the drive starts usual operation.

L8-19
(04BF)
Freq Reduction @ oH Pre-
Alarm
Sets the ratio at which the drive derates the frequency reference during an
oH
alarm.
