Absolute Encoder
An absolute encoder can detect the absolute position.
The absolute encoder uses external
battery power to store and remember
the position information of the load
system if the power supply of the servo
drive is cut. The error caused by the
noise during signal transmission is not
accumulated with the absolute encoder.
And it doesn’t require the default
position of the load to be adjusted when
the power supply is cut off, while the
incremental encoder does require it. The
absolute encoder can activate the
equipment with the memory
information. When the power supply is
cut off and the absolute position of the
load system is needed by the absolute
encoder should be used.
Absolute Encoder Wiring
An absolute encoder should be connected to the external battery
power. The battery enables the absolute encoder to remember and
maintain the information of absolute position of the load system when
the power supply of the servo drive is cut off. If the power supply to
the servo drive is cut off and the battery power is discharged below the
standard, the information memorized in the absolute encoder can be
damaged. The drive does not monitor the battery voltage directly, but
checks it indirectly through the encoder. When needed, please get the
low-voltage detection circuit ready.
