-2 Precautions When Using
the Pulse Output U
nit
 When using a G5-series Servo Drive
You can return the feedback signal from the encoder to the CPU Unit if you use a G5-series Servo
Drive with built-in EtherCAT communications.

When Using a Pulse Output Unit
A Pulse Output Unit is the same as a Servo Drive with a pulse string input. The pulses that are out-
put from the Pulse Output Unit are therefore returned to the CPU Unit.

When using a G5-series Servo Drive
You can detect Servo Drive errors in the CPU Unit if you use a G5-series Servo Drive with built-in
EtherCAT communications.
