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) 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
reference unit of the machine or controller to be used.

The setting range varies according to the encoder used.

Transferring Alarm Contents

When an absolute encoder is used, SEN signals can be utilized to transfer the alarm detec-
tion contents from PAO outputs to the host device as serial data.

Refer to 8.2.3 Alarm Display Table for a table of alarm contents.
