Analog sine/cosine interfaces
A detailed description of the analog interfaces
can be found in the document Interfaces for the
BML Magnetic Encoder.
8.1 Analog sine/cosine interface (1Vpp) (BML
BM2-N_ _ _-_ _ _-A...)
The outputs +A(+Sin)/-A(-Sin) and +B(+Cos)/-B(-Cos) must
be loaded with 120 Ohm ±10% each.
Pole width/coding Period length p [mm]
2, G, K, P, Q 1.28
5, H, M, R, S 1.50
1, 3, 6, T, U 2.00
Tab. 8-1: 1Vpp-(sin/cos) interface parameters
The maximum travel speed is limited to 20 m/s.
8.2 Analog sine/cosine interface (250mVpk) (BML
BM2-N_ _ _-_ _ _-B...)
The outputs +A(+Sin)/-A(-Sin) and +B(+Cos)/-B(-Cos) are
fed directly from the iC-Mu chip. The signal level is
250 mVpk in each case.
