Function
Sets S Rate.
Format
Ret = SmcWSetSSpeed( Id, AxisNo, SSpeed )
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 axis number.
SSpeed [ C, C++: double ] [ Python: ctypes.c_double ]
Set S Rate. The unit is [PPS].
Performs motion without
Linear (largest S character motion) when 0 is specified.
The default becomes valid when -1 is specified.
Valid range:-1, 0, setting range of S Rate
Return Value
Ret [ C, C++: long ] [ Python: ctypes.c_long ]
0 |
Terminated normally |
Non-zero |
Terminated abnormally |

Remarks
The default value is 400
pps.
Therefore, S Rate in StartSpeed(100pps) and TargetSpeed(1000pps) of default
parameters : It is 100-500,600-1000 pps.
The value is corrected by
the resolution set with SmcWSetResolveSpeed.
405pps in case of Resolution 15pps
This function is valid when
the S acceleration is set to "1: Used" in SmcWSetSAccelType
function.
When the S acceleration is set to "1: Used" in SmcWSetSAccelType
function and this function is not executed, the default is SSpeed = 0
(motion without Linear).
Example
S Rate of axis number 1
is set.
S Speed section is set to 100PPS.
C, C++
long Ret;
double SSpeed ;
SSpeed = 100;
Ret = SmcWSetSSpeed( Id , 1, SSpeed );
Python
Ret = ctypes.c_long()
SSpeed = ctypes.c_double()
SSpeed.value = 100
Ret.value = csmc.SmcWSetSSpeed( Id , 1, SSpeed )
