Drive oL2 @ Low Speed Protection
|
    
Sets the function to decrease the drive overload level at which the drive will trigger oL2 [Drive Overload] during low speed operation (6 Hz or slower) to prevent damage to the main circuit transistors.

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)
-
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%.
