Gain switching conditions
*1 Delay time (parameters Pr32) becomes effective when returning from 2nd gain to 1st gain.
*2 For the definitions of hysteresis parameters
(Pr34), see the right figure.
*3 When conditions are that torque fluctuation of
10% was experienced in the 166 É s area, set up
the value 200.
10%/166 É s = Set-up value [200] x (0.05%/166 µs )
*4 Resolution of encoder
· Figures A through E are shown in the next page.
Internal velocity control mode
Gain switching is disabled(fixed to 1 st gain).
