Function
Retrieves the setting that indicates whether to use the limit signals.
Format
Ret = SmcWGetLimitMask( Id, AxisNo, LimitMask )
Parameters
Id [ C, C++: short ] [ Python: ctypes.c_short ]
Specify the device ID retrieved by SmcWInit function.
AxisNo [ C, C++: short ] [ Python: ctypes.c_short ]
Specify the axis number.
LimitMask [ C, C++: short *] [ Python: ctypes.POINTER(ctypes.c_short) ]
Specify the address of a variable to store the value that indicates whether to use the limit signals
[ 0 | 0 | 0 | 0 | 0 | 0 | ALM | SD ]
Meaning of signals
SD |
Deceleration stop limit |
ALM |
Alarm/urgent stop limit |
Settings
0 |

Remarks
This function can be executed even if the device is in operation.
Example
A setting of the limit signal of axis number 1 effective/invalid is acquired.
C, C++
long Ret;
short LimitMask;
Ret = SmcWGetLimitMask( Id , 1, &LimitMask ) ;
Python
Ret = ctypes.c_long()
LimitMask = ctypes.c_short()
Ret.value = csmc.SmcWGetLimitMask( Id , 1, ctypes.byref(LimitMask) )
