Output Phase Loss
Protection Sel
Sets the function to enable and disable output phase loss detection. The drive starts output phase loss
detection when the output current decreases to less than 5% of the drive rated current.
Note:
The drive can incorrectly start output phase loss detection when te motor rated current is very
small compared to the drive rating.
0 : Disabled
1 : Fault when one phase is lost
2 : Fault when two phases are lost

Heatsink Fan Operation
Selection
Sets operation of the heatsink cooling fan.

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

Ambient Temperature
Setting
Sets the ambient temperature of the drive installation area.
Note:
The setting range changes when the L8-35 [Installation Method Selection] setting changes.
• When L8-35 = 0 or 2 [IP20/UL Open Type or IP20/UL Type 1]: -10 °C～+60 °C
• When L8-35 = 1 or 3 [Side-by-Side Mounting or IP55/UL Type 12]: -10 °C～+50 °C
40 °C

(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].
Note:
Contact Yaskawa or your nearest sales representative before disabling this function at low
speeds. If you frequently operate drives with high output current in low speed ranges, it can cause
heat stress and decrease the life span of drive IGBTs.
0 : Disabled (No Additional Derate)
1 : Enabled (Reduced oL2 Level)

Carrier Frequency Reduction Sets the carrier frequency reduction function. The drive decreases the carrier frequency when the
output current is more than a specified level.
