That would still need very accurate homing switches though.
- DannyBee 8y agoYasakawa has some very neat batteryless absolute encoders (so never need rehoming) in the latest sigma 7. http://www.e-mechatronics.com/download/datas/catalog/cheps80000221/cheps80000221a_0_1.pdf http://www.e-mechatronics.com/download/datas/catalog/cheps80... They use the power generated by the motor spinning to store the position.
