发格绝对光栅尺在西门子系统中的参数设置SAS/GAS/LAS

1.配置 SAS/GAS系列光栅尺

数控 CNC中的设置

MD 30200 NUM_ENCS = 2

MD 30240 ENC_TYPE = 4

MD 31000 ENC_IS_LINEAR = 1

MD 31010 ENC_GRID_POINT_DIST = 0.02 ( look  P 407= 20000 )

MD 31040 ENC_IS_DIRECT = 1

MD 34200 ENC_REFP_MODE = 0

Encoder type = linear ( Abs SSI protocol & sin/cos )

Power supply = 5V

Encoder connect = X520

SSI Protocol

Gray code

Res/bit / 100nm

Baurate = 100 kHz

Pos. Length in bits = 25 bits

Bits in fr. of pos. = 0 bits

Bits behins pos. = 1 bit

Parity bit position = yes
