Description
Droop control is invalid
Set the drooping amount at the
rated torque as a percentage with
respect to the rated frequency.
Set the time constant of the pri-
mary delay filter applied to the
torque current.

Pulse train input
Indicates division scaling factor to
the input pulse and the frequency
resolution to the input pulse
changes according to the value.
Set the frequency when the input
pulse is 0 (bias).
Set the frequency when the input
pulse is maximum (gain).
