Shell
• It is connected with the earth terminal inside the servo driver.
(Note 1) The feedback scale power output EX0V is connected with the control circuit ground that is connected to
connector X4.
(Note 2) The feedback scale power output EX5V should be 5 V±5% and 250 mA at the maximum.
When using an feedback scale whose consumption current exceeds this value, external power supply
should be prepared by the customer. It may take time to perform initialization after power-on,
depending on feedback scales.
(Note 3) In case an external power supply is used for the feedback scale, make sure that the EX5V pin is open
and no external power is supplied to the EX5V pin.
(Note 4) The maximum input frequency is 4 Mpps (after quad edge evaluation).
However, if the duty ratio of the feedback scale signal input is not 50%, it may not be able to be read
normally.
