我今天看了下
SIMODRIVE 611 digital/
SINUMERIK 840D/810D
Drive Functions
Function Manual
这本英文手册,里面有个2.2 Direct position measuring system,在这节下面有个参数1791是选择直接编码器类型的
1791 ENC_TYPE_DIRECT 默认是0
Table 2-6 Measuring–circuit type of direct measuring system
–1 No measuring system installed
0 IPU (V) unconditioned voltage signals
1 IPU (C) raw current signals (feed drives)
2–15 Reserved
16 EnDat encoder
48 SSI encoder
好象1是电流型的,我明天试下,希望有大虾指教
