Load measurement
During each travel operation, the E300 Advanced Elevator drive can measure the load in the Elevator car and provide an output to the Elevator
controller to indicate the direction of least load. This output can be used during emergency back-up operation for example, where a low voltage back-
up power supply becomes active to indicate the direction in which to travel with the least load.
