CHAPTER 2 DEFINITION & CONNECTION OF INTERFACE
SIGNALS
2.1 GSKLink Bus Interface
Bus interfaces of GSK980TDi are CN4 and CN5 (GSKLinkB and GSKLinkA), which is connected
with the GSKLink bus communication function, the feedrate servo drive unit, spindle drive unit and
extended I/O communication. GSKLink bus communication uses a loop control, and therefore, CN4
AND CN5 interfaces should be used together.
GSKLINK bus connection is shown below:

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
GSK980TDi 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)
