4.6 Setup Procedure for Elevator Applications
• When the lightest load direction is up, the drive stops after Light Load Direction Search and then accelerates upwards to
the Rescue Operation speed set in parameter d1-25. The output terminals set for "Light Load Direction" (H2-
and "Light Load Direction detection status"(H2-

Light Load Direction Search status
• When the lightest direction is down, then after Light Load Direction Detection is finished the drive immediately
accelerates to the Rescue Operation speed set in d1-25 without stopping. An output terminal set for "Light load
direction" (H2- = 54) will stay open, and an output terminal set for "Light Load Direction detection status"(H2-
= 55) will close.
