4.8.2 Low-speed Integration Function
(1) Overview
To ensure that the motor responds quickly, a small time constant must
be set so that a command enabling quick startup is issued.
If the time constant is too small, vibration or hunting occurs because of
the delayed response of the velocity loop integrator, preventing further
reduction of the time constant.
With the low-speed integration function, velocity loop integrator
calculation is performed in low-speed mode only. This function
ensures quick response and high stability while maintaining the
positioning characteristics in the low-speed and stop states.
