• Select the type of the external encoder to be used.
• For the set value, refer to the external encoder specifications.
Explanation of Settings
*1 The supported speed is the internal feedback pulse speed [external encoder pulse/s] of the external encoder
that can be processed by the Servo Drive.
Check the instruction manual of the external encoder for the speed range supported by your external encoder.
For example, the maximum speed of a serial communications external encoder with a resolution of 0.01 µm is
4 m/s.
When a serial communications speed of 5 m/s is required, choose a serial external encoder with a resolution of
0.0125 µm or lower.
*2 These are the directions that the Drive counts a 90° phase difference output.
Precautions for Correct Use Precautions for Correct Use
• If you set this object to 1 or 2 when an external encoder with a 90° phase difference output is
connected, an External Encoder Connection Error (Error No. 50.0) will occur.
• If you set this object to 0 when a serial communications external encoder is connected, a
Phase-A Connection Error (Error No. 55.0), Phase-B Connection Error (Error No. 55.1), or
Phase-Z Connection Error (Error No. 55.2) will occur.
