6.7.1.1 Software limitation
Software limitation is finished by setting working range of machine tool , also set related
parameters in CNC system.
In Axis Parameter : P13: bit parameter, software-limitation of each axis is set alone.
Bit_P11 D7 D6 D5 D4 D3 D2 D1 D0
Axis B A Z Y X
Default set 0 0 0 0 0 0 0 1
1: it is invalid of software-limitation,0: valid of software-limitation.
P3: Max Range in X-Negative Direction
P4: Max Range in X-Positive Direction
P5: Max Range in Y-Negative Direction
P6: Max Range in Y-Positive Direction
P7: Max Range in Z-Negative Direction
P8: Max Range in Z-Positive Direction
P9: Max Range in A-Negative Direction
P10: Max Range in A-Positive Direction
Warning: when shift Metric/Inch, unit is changed(mm/inch), data for limitation don’t change.
6.7.1.2 External Switch for limitation
Input Point of Limitation
Mark Port Explanation
-L PIN15_CN3 Plug Limitation in negative direction
+L PIN16 _CN3 Plug Limitation in positive direction
Type of Limitation Switch
In Axis parameter:
P21, Type of switch in Positive direction [0: NO type, 1: NC Type]
P22, Type of switch in Negative direction [0: NO type, 1: NC Type]
Wiring of Limitation
NPN Type Proximity Switch General Switch
6.7.1.3 Suggestion Usage
Fix hardware limitation switch within the range of sets by software-limitation, P11=00000001;
even if hardware switches don’t work, software-limit also will work, double safe for limitation,
Note: 1. When limitation switch is NO type(normal open type) switch,use parallel connection; when limitation
switch is NC type(normal close type) switch, use series connection.
2. CNC system could define X0&Z0 as limitation of X/Z axis. X0 signal as limitation and home of X axis,
controlled by one switch. Z0 signal as the limitation and home of Z axis, also controlled by one switch.It needs
