� Function description (defined by standard PLC program)
The control sequence and control logic of the tool change are defined by PLC program.
There
are 4 tool change modes defined as follows by standard PLC program:
1. CHTB (K11.1)=0, CHTA (K11.0)=0: tool change mode B
①During the tool change process, CNC outputs TL+ signal until the tool in-position signal
is
detected, then CNC turns off TL+ signal output and outputs TL- signal after a delay time
specified by data parameter No.082. Then CNC detects TCP signal till it is detected, the
CNC
