Function
Sets acceleration time.
Format
Ret = SmcWSetAccelTime( Id, AxisNo, AccelTime )
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.
AccelTime [ C, C++: double ] [ Python: ctypes.c_double ]
Set acceleration time. The
unit is [ms].
It is set to target speed instantly without accelerating when 0 is specified.
The default value becomes valid when -1 is specified.
Valid range: -1, 0, Setting range of acceleration time
The setting range of acceleration
time is as follows.
For SMC-2/4/8DL series: 0 to 27303.333333
For SMC-4/8DF series: 0 to 873786.666667
Return Value
Ret [ C, C++: long ] [ Python: ctypes.c_long ]
0 |
Terminated normally |
Non-zero |
Terminated abnormally |

Remarks
The default value is acceleration time: It is 50 ms.
The value is corrected by SmcWSetStartSpeed and SmcWSetTargetSpeed (SmcWSetSSpeed when S Rate operation is used).
For SMC-2/4/8DL series, the conditions under which the maximum acceleration time of 27303.333333 [ms] can be set are as follows.

For SMC-4/8DF series, the conditions under which the maximum acceleration time of 873786.666667 [ms] can be set are as follows.
ResolveSpeed |
100 |
StartSpeed |

If the default value is in use, the function need not be performed.
Example
The acceleration time of
axis number 1 is set.
The acceleration time is set to 45msec.
C, C++
long Ret;
double AccelTime ;
AccelTime = 45;
Ret = SmcWSetAccelTime( Id , 1, AccelTime );
Python
Ret = ctypes.c_long()
AccelTime = ctypes.c_double()
AccelTime.value = 45
Ret.value = csmc.SmcWSetAccelTime( Id , 1, AccelTime )
