* 1 Delay time (Pr1.16, 1.12 and 1.25) will be valid only when returning from 2nd to 1st
gain.
* 2 Hysteresis (Pr1.18, 1.23 and 1.27) is defined as the fig. below shows.
*
3 Designate with either the encoder resolution or the external scale resolution depend -
ing on the control mode.
*
4 When you make it a condition that there
is speed variation of 10r/min in 1s, set
up the value to 1.
* 5 When Pr1.15=10, the meanings of de -
lay time, level and hysteresis are differ -
ent from the normal. (refer to Fig. G)
