SmcWSetCounterMode

Function

Sets the counter mode.

Format

Ret = SmcWSetCounterMode( Id, AxisNo, ClearCntLtc, LtcMode, ClearCntClr, ClrMode )

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.

ClearCntLtc [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Set the type of counter you want to clear when the LTC signal changs from OFF to ON.

0	Do not clear the counter
1	Clear the output pulse counter
2	Clear the encoder counter
3	Clear the output pulse counter and encoder counter

LtcMode [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Set the type of counter you want to latch when the LTC signal comes in.

0	Do not use latch function
1	Latch the output pulse counter
2	Latch the encoder counter
3	Latch the output pulse counter and encoder counter

ClearCntClr [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Set the type of counter you want to clear when the CLR signal changes from OFF to ON.

0	Do not clear the counter
1	Clear the output pulse counter
2	Clear the encoder counter
3	Clear the output pulse counter and encoder counter

ClrMode (Reserved) [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
0 fixed.

Return Value

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

0	Terminated normally
Non-zero	Terminated abnormally

Initial Value

ClearCntLtc	0H : Do not clear
LtcMode	0H : Unused
ClearCntClr	0H : Do not clear
ClrMode	0 (Fixed)

Remarks

When the bit4(LTC) of CtrlIn of the SmcWSetCtrlTypeIn function is not ON, it is not recognized as LTC signal.
It is necessary to latch the counter when counter clear is performed by LTC signal. Therefore, the LtcMode bit becomes ON automatically when the ClearCntLtc bit is ON.
The counter can not be selected when it is being latched when use SMC-4/8DF series. Therefore, if latch ON setting is being set by LtcMode, other bits also become ON setting.
Every latched counter value can be read by the function that reads the latch counter.
The CLR signal is valid only for SMC-4/8DF series. Therefore, the ClearCntClr is invalid for SMC-2/4/8DL series.

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

Information on the encoder counter of axis number 1 is set.
When the LTC signal changes into OFF to ON, it doesn't clear.
When the LTC signal is input, the latch function is not used.
When the CLR signal changes into OFF to ON, it doesn't clear.
