• Be sure to use the load side encoder cables specified in this section. Using products other than those
specified may cause a malfunction.
• Contact the manufacturer of the load-side encoder being used for information on specifications,
performance, and guarantees.
Encoder cable configuration diagram
Configuration diagrams of the servo amplifier and load-side encoder are shown below. The cable to be used differs depending
on the load-side encoder.
Encoder cable configuration diagram for linear encoders
For encoder cables for linear encoders, refer to the following manual.
