SINUMERIK 840Di currently supports the following absolute encoders:
S
EQN 1325
Manufacturer of the absolute encoder EQN 1325 is Heidenhain. It is also pos-
sible to use compatible encoders of other manufacturers.
The absolute encoder EQN 1325 has the following properties:
S
Voltage signals sin/cos 1Vpp
S
EnDat interface
S
2,048 pulses/revolution
S
4,096 revolutions.
An absolute encoder can currently exclusively be used as a motor encoder (in-
direct measuring system).
