Parameterization of absolute measuring systems
Encoder types
The following encoder types are currently supported:
●
Single-turn absolute value encoder
●
Multi-turn absolute value encoder
with EnDat protocol and incremental sinusoidal encoder signals A and B, e.g. Haidenhain
EQN 1325.
EQN 1325
The absolute value encoder EQN 1325 from Heidenhain has the following properties:
●
EnDat protocol
●
PPR count: 2048 = 2

●
Positions/revolution: 8192 (13 bits)
●
Differentiable revolutions: 4096 (12 bits)
●
