Sigma II Indexer User’s Manual Using the Encoder Signal Output
5-27
Divided encoder signals are output.
The dividing ratio setting is not related to the gear ratio setting (Pn202 and 203) for
setting reference units.
Note: Dividing means converting an input pulse train from the encoder mounted on the servomotor accord-
ing to the preset pulse density and outputting the converted pulse. The units are pulses per revolution
(ppr).

SG: Connect to 0V on the position counter.
Pulse Divider Setting
Set the pulse dividing ratio in the following parameter.
Set the number of pulses for PG output signals (PAO, /PAO, PBO, /PBO).
Pulses from the servomotor encoder (PG) are divided by the preset number before
being output.
The number of output pulses per revolution is set at this parameter.
