5.2.2.2. Customized digital incremental encoder
In the encoder configuration page, besides encoder parameters for HIWIN motor with
common resolution can be chosen, parameters for various encoder brands can also be typed
in the customized setting area. Opening “Rotary” and choosing “Customized Rotary Digital”,
the resolution parameter could be entered according to the encoder specification. In the
“Encoder Resolutions” field, enter the total number of position signal for the encoder output as
the motor rotating one revolution, where the unit is counts/rev. Based on the screw pitch and
encoder resolution, the software automatically calculates the linear resolution and gives it in
the “Linear Resolution” field. The unit is um/counts. After this setting is completed, the save
function can be used to create encoder parameters. Users can load the created file for
encoder parameters (*.enc) at any time.

5.2.2.3. Encoder output setting
D2 drive sends out the encoder signal with the AqB square wave via CN2. It can be connected
to the host controller if needed. Checking “Use buffered encoder” or “Use emulated encoder”
in the “Encoder output” area, as shown in Fig. 5-22, the value in the “Output Resolution” field
will be updated according to the selected output mode.
Note. For AC servo motor with the 17-bit encoder, the Z-phase signal can be sent out to the
host controller by using the emulated encoder, as shown in Fig. 5-25.
(1) Buffered encoder output
When this option is selected, the drive will forward the signal from the motor’s encoder to
the host controller. Moreover, the “Invert” function can be checked if needed. It allows the
drive to inverse the received signal and then send out it. The resolution of output signal is
also displayed on the page for reference.
