*1 Delay time (Pr32) will be validated upon return from second gain to first gain.
*2 Definition of hysteresis (Pr34) is as illustrated in the figure below:
*3 If the condition that there is torque variation of 10% during 166 µs is included, setting should be
200.
10% / 166 µs = setting 200 x (0.05% / 166 µs)
*4 Resolution of the encoder
*5 When Pr31=10, delay time, level and hysteresis mean differently from usual cases (See Figure G).

<Caution>
Any lag in gain switching timing due to hysteresis (Pr34) is not reflected in the above figure.
