* Droop rate changeover speed (i-04) is set as the ratio (%) to the maximum speed (A-00).
Executes various the droop control settings used to, for instance, balance the torque of two motors. If the
machanical loss compensation usage selection is "use (i-19=on)," the torque command used for the droop
control is the one used for the machanical loss compensation.
Droop control usage selection (i-02):
Select whether droop control is enabled or not.
Droop start speed (i-03):
When speed becomes more than or equal to a value of the Droop start speed (i-03), droop control starts.
(When it becomes below a value specified in (i-03) as a result of the droop control, it is limited to the value.)
Note that the droop start speed (i-03) becomes the maximum speed (A-00) at 100%.
Droop rate changeover speed (i-04):
When a speed command becomes more than or equal to a setting of the Droop rate changeover speed (i-04),
a setting of the Speed_command (0.SrEF) becomes a standard amount of droop. When it is lower than or
equal to a setting of the Droop rate changeover speed (i-04), a value specified in (i-04) becomes a standard.
(When all areas are to be drooped at a rate to the Speed_command (0.SrEF), "0.0" should be set to the Droop
rate changeover speed (i-04). Conversely, when they are to be drooped at a rate of the Maximum speed
(A-00), "100.0" should be set to the Droop rate changeover speed (i-04).)
Note that the droop rate changeover speed (i-04) becomes the maximum speed (A-00) at 100%.
Droop rate (i-05):
Sets the amount of droop when the armature current command becomes 100%, at the ratio (%) of the amount
of droop against the reference revolving speed (against the speed command [or setting of the droop rate
changeover speed (i-04)] if the revolving speed is more than or equal to [or is less than or equal to] the droop
rate changeover speed (i-04)).
