SmcWSetDecelTime


Function

Sets deceleration time.

 

Format

Ret = SmcWSetDecelTime( Id, AxisNo, DecelTime )

 

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.

 

DecelTime [ C, C++: double ] [ Python: ctypes.c_double ]

Set deceleration time. The unit is [ms].
AccelTime is used as deceleration rate when 0 is specified.
However, in the case of PTP, will not attempt to decel. (Deceleration stop command : Except deceleration SmcWMotionDecStop)
The default becomes valid when -1 is specified.
Valid range: -1, 0, Setting range of deceleration time

The setting range of deceleration 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 deceleration time: It is 50 ms.

The value is corrected by SmcWSetStartSpeed and SmcWSetTargetSpeed (SmcWSetSSpeed when S Speed operation is used).

For SMC-2/4/8DL series, the conditions under which the maximum deceleration time of 27303.333333 [ms] can be set are as follows.

ResolveSpeed

600

StartSpeed

600

TargetSpeed

9829800

S rate

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

ResolveSpeed

100

StartSpeed

100

TargetSpeed

6553500

S rate

If the default value is in use, the function need not be performed.

 

Example

The deceleration time of axis number 1 is set.
The deceleration time is set to 90msec.

 

C, C++

long Ret;

double DecelTime ;

DecelTime = 90;

Ret = SmcWSetDecelTime( Id , 1, DecelTime );

 

Python

Ret = ctypes.c_long()

DecelTime = ctypes.c_double()

DecelTime.value = 90

Ret.value = csmc.SmcWSetDecelTime( Id , 1, DecelTime )
