*1: Braking torque is set as 76%.
*2: Braking torque is set as 80%.
*3: Braking torque is set as 74%.
*4: Above examples are based on rotating condition with Hitachi three phase induction motors (4poles) under frequency condition of 60Hz.
%ED = T1/T0 T1: Breaking time, T0: Repeating time.
*5: The above table is a selection example for the case of heavy duty (CT) model.
