Function
Retrieves the setting of start speed of pulse output.
Format
Ret = SmcWGetStartSpeed( Id, AxisNo, StartSpeed )
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.
StartSpeed [ C, C++: double * ] [ Python: ctypes.POINTER(ctypes.c_double) ]
Specify the address of a variable to store the value of start speed. The unit is [pps].
Return Value
Ret [ C, C++: long ] [ Python: ctypes.c_long ]
0 |
Terminated normally |
Non-zero |
Terminated abnormally |

Remarks
The value is corrected to
the multiple of the resolution set with SmcWSetResolveSpeed.
Example: 105pps in case of resolution 15pps
This function cannot be executed when the device is in operation.
Example
The pulse output beginning speed of axis number 1 is acquired.
C, C++
long Ret;
double StartSpeed ;
Ret = SmcWGetStartSpeed( Id , 1, &StartSpeed );
Python
Ret = ctypes.c_long()
StartSpeed = ctypes.c_double()
Ret.value = csmc.SmcWGetStartSpeed( Id , 1, ctypes.byref(StartSpeed) )
