SmcWSetEncType


Function

Sets the type of encoder input.

Format

Ret = SmcWSetEncType( Id, AxisNo, EncType )

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.

EncType [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Set the type of encoder input.

0

A/B (*1) 1x

1

A/B (*1) 2x

2

A/B (*1) 4x

3

U/D (*2)

4

Unused

 (*1) Multiply a 90 phase difference.
 (*2) Count up when the A signal rises, count down when the B signal falls.

Return Value

Ret [ VB.NET: Integer ] [ C, C++: long ] [ C#: int ] [ Python: ctypes.c_long ]

0

Terminated normally

Non-zero

Terminated abnormally

Initial Value

0 : A/B 1x

Remarks

The encoder counter is treated as preset value when "4 : Unused" is been set to EncType.

This function cannot be executed when the device is in operation.

After "Initial Setting function" is executed, it is necessary to execute SmcWSetInitParam.
Refer to "About Initial Setting function".

Example

The encoder input form of axis number 1 is set.

VB.NET
Dim Ret As Integer
Dim EncType As Short
Ret = SmcWSetEncType( Id , 1, EncType )

C, C++
long Ret;
short EncType;
Ret = SmcWSetEncType( Id , 1, EncType );

C#
int Ret;
short EncType;
Ret = Smc.WSetEncType( Id , 1, EncType );

Python
Ret = ctypes.c_long()
EncType = ctypes.c_short()
Ret.value = csmc.SmcWSetEncType( Id , 1, EncType )
