Absolute Encoder<br />

An absolute encoder can detect the absolute position.<br />

The absolute encoder uses external<br />

battery power to store and remember<br />

the position information of the load<br />

system if the power supply of the servo<br />

drive is cut. The error caused by the<br />

noise during signal transmission is not<br />

accumulated with the absolute encoder.<br />

And it doesn’t require the default<br />

position of the load to be adjusted when<br />

the power supply is cut off, while the<br />

incremental encoder does require it. The<br />

absolute encoder can activate the<br />

equipment with the memory<br />

information. When the power supply is<br />

cut off and the absolute position of the<br />

load system is needed by the absolute<br />

encoder should be used.<br />

Absolute Encoder Wiring<br />

An absolute encoder should be connected to the external battery<br />

power. The battery enables the absolute encoder to remember and<br />

maintain the information of absolute position of the load system when<br />

the power supply of the servo drive is cut off. If the power supply to<br />

the servo drive is cut off and the battery power is discharged below the<br />

standard, the information memorized in the absolute encoder can be<br />

damaged. The drive does not monitor the battery voltage directly, but<br />

checks it indirectly through the encoder. When needed, please get the<br />

low-voltage detection circuit ready.<br />
