Function
Sets the type of encoder input.
Format
Ret = SmcWSetEncType( Id, AxisNo, EncType )
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 the axis number.
EncType [ C, 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 [ C, C++: long ] [ 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.
C, C++
long Ret;
short EncType;
Ret = SmcWSetEncType( Id , 1, EncType );
Python
Ret = ctypes.c_long()
EncType = ctypes.c_short()
Ret.value = csmc.SmcWSetEncType( Id , 1, EncType )
