1)
Please measure an estimated disturbance torque at a low speed(about 10min
-1
). Then
please set the following calculated value to No.2758(FS15
i
), No.2345(FS16
i
).
(In using analog check board)
Setting value=|estimated disturbance torque(V)|/4.4× 7282
(In using digital check board)
Setting value=|estimated disturbance torque(A)|/(maximum amplifier current)× 7282

is set in 10mv unit. Then
proportional value to velocity is compensated as a dynamic friction.
