SmcWGetStartSpeed


Function

Retrieves the setting of start speed of pulse output.

Format

Ret = SmcWGetStartSpeed( Id, AxisNo, StartSpeed )

Parameters

Id [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
SSpecify the Deice ID retrieved by SmcWInit function.

AxisNo [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify the axis number.

StartSpeed [ VB.NET: Double ] [ C, C++: double * ] [ C#: out 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 [ VB.NET: Integer ] [ C, C++: long ] [ C#: int ] [ Python: ctypes.c_long ]

0

Terminated normally

Non-zero

Terminated abnormally

Remarks

The value is corrected to the multiple of the resolution set with SmcWSetResolve Speed.
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.

VB.NET
Dim Ret As Integer
Dim StartSpeed As Double
Ret = SmcWGetStartSpeed( Id , 1, StartSpeed )

C, C++
long Ret;
double StartSpeed;
Ret = SmcWGetStartSpeed( Id , 1, &StartSpeed );

C#
int Ret;
double StartSpeed;
Ret = Smc.WGetStartSpeed( Id , 1, out StartSpeed );

Python
Ret = ctypes.c_long()
StartSpeed = ctypes.c_double()
Ret.value = csmc.SmcWGetStartSpeed( Id , 1, ctypes.byref(StartSpeed) )
