Connected while using absolute encoder. But never connect backup battery while using encoder cables with battery unit.
*4.
Output signal should be received by linear receiver.
Note: While using 24V braker,DC24V power should be separated from the power for input and output signal (CN1). Please prepare
other power individually,
otherwise, there may be misoperation of input and output signal while power on.
