12 Descriptions of Parameter Settings | VFD-ED
When Bit 7 = 1, zero speed position control is enabled (refer to Chapter 12 Parameter Group 02 Elevator
Timing Diagram). Pr.10-22 is valid only when bit 7 is set to 1, and this function only supports PM motors.
When Bit 9 = 1, valid only when Pr.10-00 is set to 3, and the mechanical brake must be in engaged status.

You can calculate the load inertia according to the settings of motor parameters, Pr.11-02 Traction
Sheave Diameter, Pr.11-14 Motor Current at Acceleration and Pr.11-15 Carriage Acceleration. You can
use this parameter to adjust the mechanical inertia ratio.
