CHAPTER 2 DEFINITION & CONNECTION OF INTERFACE SIGNALS
2.1 Connection to Drive Unit
2.1.1 Drive interface definition
2.1.2 Code pulse and direction signals
nCP+, nCP- are code pulse signals, nDIR+, nDIR- are code direction signals. These two group
signals are both differential output (AM26LS31), it is suggested to receive by AM26LS32 externally,
and the interior circuit for them is shown in Fig. 2-2:
Fig. 2-2 Interior circuit of code pulse and direction signals
2.1.3 Drive unit alarm signal nALM
The low or high level of the drive unit alarm is set by the CNC parameter No.009 Bit0, Bit1, Bit2,
Bit3 and Bit4, its interior circuit is shown in Fig. 2-3:
Fig. 2-3 Interior circuit of drive unit alarm signal
This type of input circuit requires that the drive unit transmits signal by the types in Fig. 2-4:
