*2. DC24V power should be prepared by user. And double insulation or reinforced insulation equipment should be used for DC24V power.
*3. 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.

Cautions
！
If the input voltage of the linear drive input port is greater than 12V, please connect the appropriate current
limiting resistor in series in the circuit, otherwise, the linear drive input port may be damaged.
