Auto-detection Timing Diagram
 FOCPG/PM Control Mode: In the time setting in Pr.06-47, the drive remains at zero-speed and it is able
to determine the elevator loading without performing forward/reverse run. Then the elevator operates in
the power regeneration direction (the motor is in power generating status). Refer to the diagram below
for the Auto-Detection Timing Graph.
