Pr.06-46 is enabled when the external terminal is detecting for the emergency power.
When Pr.06-46 is set to 1 and a forward/reverse run command is given, the drive will begin to
detect for the elevator loading and operates in the power regeneration direction (the motor is in
power generating status). The drive will use and operate in the direction that was detected as
its power regeneration direction. The drive will not operate in user command direction for
safety purpose, to prevent voltage drop of emergency power.
VF and SVC control mode: within the time setting of Pr.06-47, the drive detects the elevator
loading status by performing forward/reverse run. Then the elevator operates in power
regeneration direction (the motor id in power generating status). Refer to the diagram below for
the Auto-Detection Time Graph.
