oL2@LoSpeed Selection
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 the manufacturer 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.
