2.2 Being Connected with Spindle Encoder
2.2.1 Spindle encoder interface definition
2.2.2 Signal explanation
*PCS/PCS,*PBS/PBS,*PAS/PAS are the encoder C, B, A phases differential input signals
respectively, which are received by 26LS32; *PAS/PAS,*PBS/PBS are orthogonal square
wave with
phase shift 90°and their maximum signal frequency is less than 1MHz; the encoder pulses
for
TAC-100XT are set at will by parameter, the setting range is from 100 to 5000.
Its interior circuit is shown in Fig. 2-13: (n=A, B, C)

2.2.3 Being connected with spindle encoder interface
TAC-100XT/TAC-100XT-V is connected with spindle encoder shown in Fig. 2-14, and it
uses
twisted pair cables. (exemplified by CHANGCHUN YIGUANG ZLF-12-102.4BM-C05D
