SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
0 : During Run, w/ L8-11 Off-Delay
The drive turns on the fan when a Run command is active.
1 : Always On
The fan turns on when you supply power to the drive. When you release the Run command and the delay time set in
L8-11 [HeatsinkCoolingFan Off DelayTime]
is expired, the fan stops. his setting extends the fan lifetime.
2 : On when Drive Temp Reaches L8-64
The fan turns on when the drive detects that the main circuit is overheating.

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 Fan Operation Selection = During Run, w/ L8-11 Off-Delay]

Ambient Temperature
Setting
Sets the ambient temperature of the drive installation area.
40 °C
(Determined by L8-35)
The drive automatically adjusts the drive rated current to the best value as specified by the set temperature. Set the
ambient temperature of the area where you install the drive to a value that is more than the drive rating.
Refer to
Derating Depending on Ambient Temperature on page 544

ambient temperature.

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
(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.
