Sigma II Indexer User’s Manual Absolute Encoders

5-45

Note: 1. The absolute position data within one revolution is the value before dividing.

2. Absolute position data increases during forward rotation. (Not valid in reverse rotation mode).

Incremental Pulses and Origin Pulses

Just as with normal incremental pulses, initial incremental pulses which provide

absolute data are first divided by the frequency divider inside the Servo Amplifier

and then output.

Setting the Pulse Dividing Ratio

Use the following parameter to set the pulse dividing ratio.

This parameter sets the number of output pulses for PG output signals (PAO, /PAO,

PBO, /PBO).

Pulses from the motor encoder (PG) are divided by the preset number before being

output.
