Data
Even parity
Start bit
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 abso-
lute data are first divided by the frequency divider inside the Servopack and then output.

Setting the Pulse Dividing Ratio
Use the following user constant to set the pulse dividing ratio.
Pn201
PG Divider
This user constant sets the number of output pulses for PG output signals (PAO, /PAO, PBO,
/PBO) sent externally.
Pulses from the motor encoder (PG) are divided by the number of pulses set here before being
output.
The set value is the number of output pulses per revolution. Set this value according to the refer-
ence unit of the machine or controller to be used.
The setting range varies according to the encoder used.
