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 Off-Delay
Time
Sets the length of time that the drive will wait before it stops the cooling fan after it cancels

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.
