10.4.2
Enhanced dividing output resolution
The upper limit of dividing output 16384 [P/R] (equivalent to 16-bit)
is increased to 262144 [P/R] (equivalent to 20-bit).
10.3.2
Reference pulse input multiplication
range switching
The reference pulse multiplication can be selected from 1 to 99.
Use this function if the reference pulse frequency cannot be increased
from the host controller.
The setting cannot be changed during operation.
10.3.3
Second stage notch filter
Changeable Q value
Second stage notch filter is added so that two notch filters, first stage
and second stage notch filters, can be set for two resonance generating
points.
The setting of parameter “Q value” that determines the sharpness of
notching can be changed to suppress the influence on the control loop
and interaction between two notch filters.
10.3.4
Automatic gain switching
The switching between Gain Setting 1 and Gain Setting 2 is automati-
cally carried out according to the conditions of position reference and
position error.

Adaptation to single-turn data abso-
lute encoders
Adapted to single-turn data absolute encoders mounted on direct-
drive motors
