Function
Sets start speed for pulse
output.
When the default value is used, this function need not be executed.
Format
Ret = SmcWSetStartSpeed( 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 axis number.
StartSpeed [ C, C++: double ] [ Python: ctypes.c_double ]
Set start speed. The unit
is [PPS].
The default value becomes valid when -1 is specified.
Valid range: -1, Setting range of motion speed
Setting
range of motion speed
SMC-2/4/8DL series : 0.29296875-9829800
SMC-4/8DF series : 0.0732421875-6553500
Return Value
Ret [ C, C++: long ] [ Python: ctypes.c_long ]
0 |
Terminated normally |
Non-zero |
Terminated abnormally |

Remarks
The default value is 100 pps.
The value that can be the
setting by the default resolution (1pps) it is from 1 to 16383 for SMC-2/4/8DL
series.
Please change the speed resolution by the SmcWSetResolveSpeed
function when you set the speed of 16383[pps] or more.
The value that can be the
setting by the default resolution (1pps) it is from 1 to 65535 for SMC-4/8DF
series.
Please change the speed resolution by the SmcWSetResolveSpeed
function when you set the speed of 65535[pps] or more.
The value is corrected by the resolution set with SmcWSetResolveSpeed.
Example: 105pps in case of 15pps Resolution.
Example
The pulse output beginning speed of axis number 1 is set.
C, C++
long Ret;
double StartSpeed ;
StartSpeed = 200;
Ret = SmcWSetStartSpeed( Id , 1, StartSpeed );
Python
Ret = ctypes.c_long()
StartSpeed = ctypes.c_double()
StartSpeed.value = 200
Ret.value = csmc.SmcWSetStartSpeed( Id , 1, StartSpeed )
