Frame ground
Note 1) EX5V of external scale power supply output is 5 V ± 5%, 250 mA MAX.
If you are using an external scale with more current consumption,
please prepare the external power supply by the customer.
Also, some external scale may take time to initialize after turning on the power.
In that case, it is possible to adjust by adjusting the power-on wait time which is the function
of the servo driver.For details, refer to "Technical
Note 2) If the external scale is driven by an external power supply, leave the EX 5 V pin open so that no voltage is
supplied to this pin from the outside.
Note 3) The EX0V of the external scale power supply output is connected to the control circuit ground connected to the
connector X5
Note 4) Up to 4 Mpps can be received with A / B phase multiplied by 4. However, please note that if the duty ratio of
the scale input signal waveform is not 50%, it may not be able to be read normally.

• The power necessary to store multi-turn data is supplied to the absolute
encoder via BTP-0 (pin 3) and BTN-0 (pin 4) of encoder connector
X6 .
• The battery for the absolute encoder should be connected using any of
the following methods.
(1) Directly connected to the motor side.
BTN-I 15
(2) Connection to the encoder cable.
(3) Connection to this connector.
Pin No.
• Do not connect anything to this connector.
