6-2 Encoder Dividing Rate for Servo Controllers
Encoder output pulses for OMNUC W-Series AC Servo Drivers can be set within a range
of 16 to 16,384 pulses/revolution by setting the encoder dividing rate. Depending on the
Controller’s encoder input maximum response frequency limits, however, the maximum
numbers of revolutions are limited as shown in the following tables.

Note 1. In this table, the dividing rates are shown in the top line above the multipliers.
Note 2. For example, if operating a CS1W-MC221/421(-V1) at 5,000 r/min., set Pn201 (Encoder di-
vider rate) to 4,096 (pulses/r) maximum.
