Common FANUC servo motor encoders have the following models:
A860-2070-T321 βiA1000 for FANUC βi servo motor absolute (no temperature detection)
A860-2020-T301 βiA128 for FANUCβi servo motor absolute
A860-2005-T301 αiI1000 for FANUCαi servo motor increment
A860-2000-T301 αiA1000 for FANUCαi servo motor absolute
A860-0365-V501 αI64 for FANUCα servo motor increment
A860-0360-V501 αA64 for FANUCα servo motor absolute
Expand your knowledge:
(1) FANUC absolute position encoder can replace incremental encoder, but incremental encoder cannot replace absolute encoder.
(2) All βi servo motor encoders are absolute.
(3) Using an absolute encoder, you can set the machine tool origin through parameter 1815.
The first step is to change the two parameters 1815.4 and 1815.5 to 0.
The second step is to swing the machine tool axis with the handwheel to near the origin of the machine tool.
The third step is to change the 1815 parameters 1815.5APC and 1815.4APZ to 1 at the same time, turn off and on the computer, and the origin is set successfully.
If the setting is unsuccessful, you can move the shaft about 2 cm with the handwheel and repeat steps 123.
(4) Why is the origin lost?
The FANUC absolute position encoder has one more memory chip than the incremental position encoder.
The origin data is recorded in the chip. The absolute position encoder has 2 more wires than the incremental position encoder, 0V and 6V. The battery on our driver supplies power to the memory chip of the encoder through these 2 wires.
As can be seen from the above figure, when the motor encoder plug is unplugged, or the JF1 plug is unplugged, or the battery is unplugged, the encoder origin may be lost. Mori Seiki and Makino machine tools generally provide collective power to the driver through the CXA2A and CXA2B plugs, so it is easy for the origins of all axes to be lost at the same time.
(5) Replace the encoder battery
If the low battery voltage alarm appears and the battery needs to be replaced, the battery must be replaced while the phone is on.
(6) Industrial smart charging box, never need to change batteries
