Pr.11-14 Motor Current at Acceleration
Press
Press
 The maximum motor current measured when the elevator is tuning in automatic mode.
Pr.11-05 Mechanical Inertial Ratio
Press
Press
 You can calculate the load inertia according to the settings of motor parameters, Pr.11-01 to
Pr.11-04 and Pr.11-14 Motor Current at Acceleration and Pr.11-15 Carriage Acceleration. You
can use this parameter to adjust the mechanical inertia ratio.
