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 10 r/min in
1s, set up the value to 1.
*
5 When Pr1.15=10, the meanings of
delay time, level and hysteresis are
different from the normal. (refer to Fig. G)
